Advaita Chakra Theory — Emergent Relativistic Quantum Field Theory from a Locked Chakra Lattice

Abstract

This work presents a rigorous derivation of a relativistic quantum field theory (QFT) as the long-wavelength, low-energy limit of a microscopic quantum many-body system defined by the Advaita Chakra Theory (ACT). The ACT model consists of a lattice of quantum rotors with compact angular variables (“chakras”) interacting via local, translation-invariant couplings. In the fully locked phase, the Goldstone sector of ACT gives rise to a massless scalar field theory on an emergent Lorentzian spacetime. Using tools from lattice field theory, Lieb–Robinson bounds, and constructive QFT, we establish convergence of correlation functions, microcausality, and Lorentz invariance in the scaling limit. The resulting field satisfies the Wightman axioms and supports a local effective field theory at low energies. This result provides a concrete example of how relativistic QFT can emerge from a discrete, nonrelativistic quantum system via continuum scaling and coarse-graining.

The Emergence of Relativistic Quantum Field Theory from the Admissibility Conditions for Coherent Projection

Marcus Schmieke

The Quantum Blueprint Formalism (QBF) has derived nonrelativistic quantum mechanics — the Schrödinger equation — as the circulation-dominated limit of the Mother Equation on the pre-coherent possibility space M_s (Schmieke, 2026r). That derivation operates in a finite-dimensional phase space and therefore yields quantum mechanics for a fixed number of particles. However, the Standard Model is a relativistic quantum field theory (QFT), requiring: (i) infinitely many degrees of freedom, (ii) creation and annihilation of particles, (iii) Lorentz invariance, (iv) the spin-statistics theorem, and (v) ultraviolet regulation. This paper extends the derivation to the full infinite-dimensional structure of M_s and shows how these five features arise from the same admissibility conditions (A1)–(A3) and the same Mother Equation, given the additional assumption that M_s is an infinite-dimensional separable Hilbert manifold (Assumption 2.1). Second quantization, the Klein–Gordon equation, Fock space, and Lorentz invariance are derived. The Dirac equation is constrained (it follows if the circulation field carries spinor structure). The spin-statistics connection is derived for free fields and constrained for interacting fields (requiring perturbative microcausality). A natural ultraviolet cutoff follows qualitatively from (A3); the specific scaling is motivated but not yet rigorously proven.

Minimal Proper Time and Deterministic Microstates: Emergent Quantum Fields and Relativistic Spacetime

Alessio Maiezza

We develop a top-down counterpart of the minimal proper-time formulation of quantum field theory previously introduced as an effective bottom-up framework. Starting from a deterministic pre-geometric substrate of causally ordered events, we show how coarse-graining over microscopic histories leads, at low energies, to an effective Nambu-like quantum dynamics. The elementary deterministic update is identified with the minimal proper-time step, while the growth of coarse-grained equivalence classes controls both the ultraviolet dissipative correction and the scale dependence of the effective quantization strength, encoded in a running Planck constant. In this way, the proper-time cutoff kernel of the bottom-up formulation acquires a microscopic interpretation as the inverse growth of unresolved deterministic histories. In the infrared limit, the dissipative term vanishes and standard unitary quantum field theory is recovered. The same coarse-grained structure also provides a natural setting for an emergent relativistic spacetime geometry, compatible in the macroscopic limit with Einstein gravity. The resulting picture suggests a common deterministic origin for minimal-scale structure, quantum behavior, and relativistic spacetime.

The Ultraviolet Structure of Quantum Field Theories. Part 2: What is Quantum Field Theory?

Djordje Radicevic

This paper proposes a general framework for nonperturbatively defining continuum quantum field theories. Unlike most such frameworks, the one offered here is finitary: continuum theories are defined by reducing large but finite quantum systems to subsystems with conserved entanglement patterns at short distances. This makes it possible to start from a lattice theory and use rather elementary mathematics to isolate the entire algebraic structure of the corresponding low-energy continuum theory. The first half of this paper illustrates this approach through a persnickety study of (1 + 1)D continuum theories that emerge from the $\mathbb{Z}_K$ clock model at large $K$. This leads to a direct lattice derivation of many known continuum results, such as the operator product expansion of vertex operators in the free scalar CFT. Many new results are obtained too. For example, self-consistency of the lattice-continuum correspondence leads to a rich, novel proposal for the symmetry breaking structure of the clock model at weak coupling, deep in the BKT regime. This also makes precise what one means by "continuous" when saying that continuous symmetries cannot be broken in (1+1)D. The second half of this paper is devoted to path integrals for continuum theories of bosons and fermions defined in this finitary formalism. The path integrals constructed here have both nonperturbative lattice definitions and manifest continuum properties, such as symmetries under infinitesimal rotations or dilatations. Remarkably, this setup also makes it possible to generalize Noether's theorem to discrete symmetries.

QM I: Phase Differential Theory and the Emergence of Quantum Mechanics

Graham Fincham, Daniel John Hilton

Phase Differential Theory (PDT) proposes that quantum mechanics emerges as an effective description of a deeper dynamical phase manifold. In this framework, four scalar phase fields define a locked background whose long‑wavelength envelope dynamics reproduce the Schrödinger equation. The Born rule arises as the natural conserved probability density compatible with locality and continuity of phase flow, and measurement is interpreted as phase synchronisation between subsystems rather than wavefunction collapse. This paper develops a controlled derivation of the Schrödinger equation as an envelope approximation, identifies the conserved probability current associated with phase flow, and shows that |ψ|² is the natural density selected by locality, positivity, and conservation. Measurement is modelled as a dynamical locking of relative phase between system and apparatus, yielding discrete outcomes without introducing non‑unitary dynamics at the fundamental level. All results are obtained within a low‑energy, long‑wavelength effective regime. The microscopic equations of motion for the phase manifold are intentionally deferred, as the effective envelope theory presented here is self‑contained and does not require explicit microscopic specification.

Generalized Foldy-Wouthuysen approach for the derivation of non-relativistic effective field theories

Tobias Asano, Fabio Di Pumpo, Enno Giese +1 more

Effective field theories (EFTs) are a powerful framework for performing high-precision calculations at reduced complexity compared to their fundamental counterparts. A particularly important class of EFTs arises in the non-relativistic (NR) regime. Their construction relies on a different realization of the underlying symmetries, since Lorentz invariance is no longer manifest in covariant form in the NR regime. This behavior imposes a link between certain matching coefficients, and therefore additional constraints, commonly referred to as hidden Lorentz invariance. These constraints are established in quantum field theories on inertial flat spacetime, such as NR quantum electrodynamics. However, deriving these constraints becomes considerably more involved for theories involving physics beyond the Standard Model or formulated in non-inertial spacetime backgrounds, where the hidden symmetry structure is less transparent. In this work, we present an approach to obtain the NR EFT by first constructing a relativistic EFT and then performing a generalized NR reduction based on an extended Foldy-Wouthuysen transformation. We illustrate this method by a quantum chromo-electrodynamics EFT for inertial flat spacetime, describing both electromagnetic and strong interactions, and show how it reduces to the established Lagrangian of NR quantum chromodynamics and electrodynamics. The hidden Lorentz invariance emerges as a direct consequence of the construction. This approach provides a route to obtain the NR limits of more complex theories, \eg Dirac fields in non-inertial spacetime or extensions involving physics beyond the Standard Model. As an example, we apply the method to add the coupling of a pseudoscalar axion field in a simplified model and derive its NR limit.

2000]: ‘Entanglement and Open Systems in Algebraic Quantum Field Theory

Rob Clifton, Hans Halvorson

Entanglement has long been the subject of discussion by philosophers of quantum theory, and has recently come to play an essential role for physicists in their development of quantum information theory. In this paper we show how the formalism of algebraic quantum field theory (AQFT) provides a rigorous framework within which to analyze entanglement in the context of a fully relativistic formulation of quantum theory. What emerges from the analysis are new practical and theoretical limitations on an experimenter’s ability to perform operations on a field in one spacetime region that can disentangle its state from the state of the field in other spacelike-separated regions. These limitations show just how deeply entrenched entanglement is in relativistic quantum field theory, and yield a fresh perspective on the ways in which the theory differs conceptually from both standard nonrelativistic quantum theory and classical relativistic field theory. “...despite its conservative way of dealing with physical principles, algebraic QFT leads to a radical change of paradigm. Instead of the Newtonian view of a space-time filled with a material content one enters the reality of Leibniz created by relation (in particular inclusions) between ‘monads ’ (∼ the hyperfinite type III1 local von Neumann factors A(O) which as single algebras are nearly void of physical meaning) ” Schroer (1998, p. 302).
