Abstract

We propose and investigate a generalized Schrödinger equation by introducing a fractional Riesz derivative to account for anomalous transport and a memory kernel to describe temporal nonlocal effects. Additionally, we include a long-range interactions term, modeled by an integral operator, which captures spatially extended interactions. Using the Green function approach, we derive analytical solutions and explore their implications in the time-space domain. Our findings reveal novel quantum phenomena arising from the interplay of fractional dynamics, nonlocal potentials, and memory effects, including the emergence of new local maxima in the evolution of Green's functions and distinct localization behaviors.

Quantum Dynamics in a Comb Geometry: Green Function Solutions with Nonlocal and Fractional Potentials

Enrique Chipicoski Gabrick, Ervin Kaminski Lenzi, Antonio S. M. de Castro +2 more

We investigate a generalized quantum Schrödinger equation in a comb-like structure that imposes geometric constraints on spatial variables. The model is extended by the introduction of nonlocal and fractional potentials to capture memory effects in both space and time. We consider four distinct scenarios: (i) a time-dependent nonlocal potential, (ii) a spatially nonlocal potential, (iii) a combined space–time nonlocal interaction with memory kernels, and (iv) a fractional spatial derivative, which is related to distributions asymptotically governed by power laws and to a position-dependent effective mass. For each scenario, we propose solutions based on the Green’s function for arbitrary initial conditions and analyze the resulting quantum dynamics. Our results reveal distinct spreading regimes, depending on the type of non-locality and the fractional operator applied to the spatial variable. These findings contribute to the broader generalization of comb models and open new questions for exploring quantum dynamics in backbone-like structures.

Stability and Simulation of Fractional Dynamics in Nonhomogeneous Media via Generalized Quantum-Hadamard Operators

Rabha Waell Ibrahim

In this study, we extend the concept of the quantum Gamma function (q-Gamma) by introducing a new (q,\tau)-deformed Gamma function. This generalization allows us to construct an enriched family of Hadamard-type fractional operators, which we then apply to the analysis of memory and decoherence in open quantum systems. The inclusion of the deformation parameter q together with the delay-like scaling parameter \tau makes the proposed (q,\tau)-Hadamard framework particularly suited to capture nonlocal and non-Markovian effects, thereby offering a flexible tool for describing structured reservoirs and anomalous dissipation. To investigate the analytical consequences, we employ a (q,\tau)-Mittag-Leffler function, through which explicit solutions are obtained for a class of fractional differential equations, with particular emphasis on population dynamics models. These solutions reveal a variety of memory-driven features, including sub-exponential decay of coherence and the occurrence of revival phenomena. Both the fractional order alpha and the deformation parameters play a decisive role in shaping the temporal behavior. Beyond population models, the framework also provides insights into fractional quantum master equations, quantum walks with fractional memory, and noise effects in quantum information processing.

Nonlocal quantum mechanics: fractional calculus approach

Nick Laskin

We show that a quantum system with long-range interparticle interaction can be described by invoking fractional calculus tools. The system under consideration is nonlocal exciton-phonon quantum dynamics on a 1D lattice. It has been shown that long-range power-law exciton-exciton interaction leads to a nonlocal integral term in the motion equation of an exciton subsystem if we go from discrete to continuous space. In some particular cases for power-law interaction with noninteger power, the nonlocal integral term can be expressed through a spatial derivative of fractional order. Considering exciton-phonon dynamics with long-range exciton-exciton interaction, we have obtained the system of two coupled equations, where one is the quantum fractional differential equation for the exciton subsystem while the other is a standard differential equation for the phonon subsystem. It has been found that the system of two coupled equations can be further simplified to come up with the following fractional nonlinear equations of motion: nonlinear fractional Schrödinger equation, nonlinear Hilbert-Schrödinger equation, fractional generalization of Zakharov system, and fractional Ginzburg-Landau equation. The appearance of fractional differential equations in the continuum limit of lattice dynamics allows us to apply powerful tools of fractional calculus to study nonlocal quantum phenomena.

Fractional nonlocal Maxwell–Bloch dynamics: Soliton propagation, optical memory effects, and chaotic electromagnetic interactions in photonic media

Kolade Matthew Owolabi, Sonal Jain, Eben Maré

Classical Maxwell–Bloch models are often inadequate for describing electromagnetic wave propagation in complex optical media where memory effects, anomalous relaxation processes, and long-range electromagnetic interactions are important. To address these limitations, this work develops a fractional nonlocal Maxwell–Bloch framework that simultaneously incorporates Caputo fractional temporal memory and nonlocal electromagnetic coupling. The principal novelty lies in the unified treatment of temporal memory and spatial nonlocality within the Maxwell–Bloch framework, together with the corresponding analysis of their effects on optical-wave dynamics. The proposed model captures hereditary polarization dynamics and spatially distributed electromagnetic interactions that are not represented in the standard local integer-order formulation. The analytical part establishes the well-posedness structure of the governing system, including existence, boundedness, and stability properties of solutions in appropriate functional spaces. A spectral stability analysis is further employed to characterize fractional instability thresholds and transitions in the resulting wave propagation. Numerical simulations demonstrate the emergence of localized fractional optical structures, memory-dependent pulse propagation, nonlinear wave interactions, and complex dynamical regimes. A systematic parametric study further shows that variations in the fractional order significantly modify the electric-field profile, energy evolution, and pulse amplitude. The results demonstrate that the combined effects of fractional temporal memory and spatial nonlocality can substantially alter the propagation and stability of electromagnetic waves compared with the classical Maxwell–Bloch limit. The framework therefore provides a unified mathematical and computational basis for investigating memory-dependent and spatially nonlocal optical dynamics.

From degenerate solution spaces to unique states: exploring fractional operators’ impact on fractional Schrödinger equation in linear potential

Xueling Duan, Ke Deng

Abstract This study systematically investigates the physical significance and advantages of infinite-memory fractional operators in the fractional Schrödinger equation for a linear potential. We derive and compare analytical solutions for both infinite-memory and finite-memory fractional operators, highlighting their distinct mathematical structures and physical implications. For infinite-memory operators, we identify a rich degeneracy in the solution space due to non-local historical dependence, whereas finite-memory operators yield unique solutions. Furthermore, we demonstrate that the unique solutions generated by finite-memory operators represent a certain degenerate form of the solutions produced by infinite-memory operators. Additionally, we analyze their convergence and physical admissibility. Our results indicate that the choice of fractional operator significantly influences quantum behavior, which holds important implications for the development and application of fractional quantum mechanics.

Anomalous transport in long-ranged open quantum systems

Abhinav Dhawan, Katha Ganguly, Manas Kulkarni +1 more

We consider a one-dimensional fermionic lattice system with long-ranged power-law decaying hopping with exponent $\ensuremath{\alpha}$. The system is further subjected to dephasing noise in the bulk. We investigate two variants of the problem: (i) an open quantum system where the setup is further subjected to boundary reservoirs enabling the scenario of a nonequilibrium steady-state charge transport, and (ii) time dynamics of an initially localized single-particle excitation in the absence of boundary reservoirs. In both variants, anomalous superdiffusive behavior is observed for $1<\ensuremath{\alpha}<1.5$, and for $\ensuremath{\alpha}>1.5$ the setup is effectively short ranged and exhibits conventional diffusive transport. Our findings are supported by analytical calculations based on the multiple scale analysis technique that leads to the emergence of a fractional diffusion equation for the density profile. Our study unravels an interesting interplay between long-range interaction and dephasing mechanism that could result in the emergence of unconventional behavior in open quantum systems.
