The foundations of modern theoretical physics rest on the interplay between quantum dynamics, thermodynamics, and spacetime geometry. While quantum mechanics describes microscopic dynamics through unitary time evolution, thermodynamic phenomena introduce irreversibility and entropy production. In this work we propose a unified framework in which quantum evolution is formulated on a complex-time manifold that naturally incorporates both dynamical and thermodynamic structures. We introduce a complex-time coordinate combining physical time and thermal flow and derive a generalized evolution equation from a variational principle defined on a complex-time geometric manifold. The resulting equation contains both Hamiltonian dynamics and geometric diffusion terms governed by the Laplace–Beltrami operator. This formulation provides a geometric interpretation of thermodynamic irreversibility within quantum theory and establishes connections with Euclidean quantum field theory, geometric quantum mechanics, and thermal time hypotheses. Possible implications for quantum statistical mechanics and information flow in gravitational systems are discussed.

Modern theoretical physics rests on the interplay between quantum dynamics, thermodynamics, and spacetime geometry.Quantum mechanics describes microscopic evolution through unitary time dynamics, while thermodynamic systems exhibit irreversible entropy production. Meanwhile, geometric formulations of quantum mechanics and statistical physics suggest that physical laws may possess an underlying geometric structure. In this work we introduce a unified framework in which quantum evolution occurs on a complex-time manifold that incorporates both dynamical time and thermodynamic flow. We construct a geometric variational principle on this extended temporal manifold and derive a generalized quantum evolution equation that contains both Hamiltonian dynamics and geometric diffusion terms. The resulting theory provides a natural bridge between quantum mechanics, statistical mechanics, and informationgeometry. We explore the implications of the framework for quantum statistical systems, quantum field theory, and information flow in gravitational systems.
We introduce the \textbf{Complex-Time Quantum-Thermal-Geometric (CTQTG) Equation}, a novel framework unifying quantum dynamics, thermal diffusion, and information-geometric feedback within a single complex-time formalism. By defining the complex-time coordinate θ=τ+it/ℏ, where τ represents imaginary (thermal) time and t real (unitary) time, we derive the governing equation for the quantum-thermal-geometric state Ψ(θ): \begin{equation}\partial_\theta \Psi(\theta) = - H(\theta) \Psi(\theta) - \alpha \, \Delta_\theta \Psi(\theta),\end{equation} where H(θ) is the (possibly complex-time dependent) Hamiltonian, Δθ is the Laplace-Beltrami operator on the complex-time manifold, and α is a coupling constant controlling the strength of quantum-thermal-geometric interaction. The CTQTG Equation generalizes standard Schr\"odinger and heat equations, naturally incorporates unitary evolution and thermalization, and predicts novel phenomena such as oscillatory entanglement-wave modes driven by geometric feedback. We present explicit analytic solutions for constant and perturbed Hamiltonians, discuss limiting behaviors, and highlight potential experimental and theoretical implications for emergent spacetime, entanglement dynamics, and black hole microstate fluctuations. This work establishes a new class of dynamical equations in which quantum, thermal, and geometric effects are inseparable, providing a foundational framework for future research in complex-time physics.

We introduce an extension of the Complex-Time Quantum-Thermal-Geometric (CTQTG) framework to \textit{curved complex-time manifolds}, unifying quantum evolution, thermal effects, and entanglement-driven geometric dynamics. The evolution of the complex-time wavefunction Ψ(θ,x) is governed by the generalized CTQTG equation:\begin{equation}\boxed{\partial_\theta \Psi(\theta,x) = - H(\theta,x) \Psi(\theta,x) - \alpha \Delta_\theta^{(g)} \Psi(\theta,x)}\end{equation}where θ=τ+it/ℏ combines imaginary time τ (inverse temperature) and real time t, Δθ(g) is the Laplace-Beltrami operator on the curved complex-time manifold, and α quantifies the quantum-thermal-geometric coupling. Analytical solutions reveal entanglement wave propagation modulated by manifold curvature, and in the strong-coupling limit (α≫1) the system exhibits emergent spacetime structures. This framework provides a unified approach to explore holographic correspondences, thermally-modulated quantum interference, and the dynamical generation of spacetime geometry from entanglement patterns.
We introduce a unifying theoretical framework based on \emph{complex time} defined on a K\"ahler manifold,which coherently integrates quantum unitary evolution, thermodynamic relaxation, and Riemannian geometric dynamicswithin a single dynamical system. By elevating time from a real parameter to a fundamental complex variableθ=τ+iℏt,we demonstrate that quantum mechanics, statistical thermodynamics, and gravitational geometryarise as distinct real-sector projections of an underlying holomorphic structure.A fundamental complex-time evolution equation is derived, which admits consistent Hilbert-space inner products,strict probability conservation, and natural coupling to the spacetime metric gμν.We prove that the theory reduces exactly to the Schrödinger equation, imaginary-time thermal dynamics,and geometric diffusion in their respective physical limits, while yielding testable predictionsconcerning wave-packet broadening, energy-level renormalization by geometry, and complex causal structure.This framework suggests that observed real spacetime is merely the \emph{real slice} of a fundamental complex manifold,providing a mathematically consistent route toward quantum-gravity unification.
We present a first-principles derivation of a master equation that unifies quantum dynamics, thermal effects, and Riemannian geometry within a holomorphic framework based on complex time. Starting from five fundamental axioms—complex-time holomorphy, geometric consistency, probability conservation, dimensional completeness, and spectral stability—we derive the Complex Time Quantum Thermal Geometric (CTQTG) equation: \begin{equation}\frac{\partial \Psi}{\partial \theta} = -\frac{i}{\hbar}H\Psi - i\lambda \frac{\hbar G}{c^2} \Delta_g \Psi, \qquad \theta = t + i\frac{\hbar}{2k_B T},\end{equation} where Ψ is a temperature-dependent effective wave function in the sense of thermal field theory, H is the Hamiltonian, Δg is the Laplace-Beltrami operator on a Riemannian manifold, and λ is an order-one dimensionless constant uniquely fixed by the Planck scale. The complex time variable θ unifies real-time unitary evolution with imaginary-time thermal relaxation, reflecting the KMS condition of thermal field theory. We prove that the equation preserves a conserved norm, reduces to the Schr\"odinger equation in the flat-space zero-temperature limit, and is globally well-posed on compact manifolds. Exact analytic solutions are constructed, including plane waves and Gaussian wave packets, revealing gravity-induced modifications to quantum dynamics such as temperature-dependent wave-packet broadening and thermal suppression of high-momentum modes. The equation contains no free parameters beyond λ and offers a mathematically consistent framework for exploring the interface between quantum mechanics, general relativity, and thermodynamics. We discuss testable predictions in matter-wave interferometry and ultra-cold atom systems.
