Fractional-Time Jaynes-Cummings Model: Unitary Description of its Quantum Dynamics, Inverse Problem and Photon Statistics
Thiago T. Tsutsui, Danilo Cius, Antonio S. M. de Castro +1
We analyze the quantum dynamics of the fractional-time Jaynes-Cummings model using a recent unitary framework for the fractional-time Schrödinger equation. We examine how the fract…
k-Uniform complete hypergraph states stabilizers in terms of local operators
Gabriel M. Arantes, Vinícius Salem, Danilo Cius +1
In this work, we present a novel method to express the stabilizer of a k-uniform complete hypergraph state as a linear combination of local operators. Quantum hypergraph states gen…
Canonical quantization for Equilibrium Thermodynamics
Luis F. Santos, Victor Hugo M. Ramos, Danilo Cius +2
We formulate a canonical quantization of Equilibrium Thermodynamics by applying Dirac's theory of constrained systems. Thermodynamic variables are treated as conjugate pairs of coo…
Revisiting the Jaynes-Cummings model with time-dependent coupling
Thiago T. Tsutsui, Danilo Cius, Antonio Vidiella-Barranco +2
The Jaynes-Cummings (JC) model stands as a fully quantized, fundamental framework for exploring light-matter interactions, a timely reflection on a century of quantum theory. The t…
Non-Markovian Light-Matter Dynamics in the Time Fractional Jaynes-Cummings Model with Modulated Coupling
Enrique C. Gabrick, Thiago T. Tsutsui, Danilo Cius +3
We investigate the fractional time description of a generalized quantum light-matter system modeled by a time-dependent Jaynes-Cummings (JC) interaction, with different coupling ty…
Unitary description of the Jaynes-Cummings model under fractional-time dynamics
Danilo Cius
The time-evolution operator corresponding to the fractional-time Schrödinger equation is nonunitary because it fails to preserve the norm of the vector state in the course of its e…
Contextuality in anomalous heat flow
Naim Elias Comar, Danilo Cius, Luis Felipe Santos +2
In classical thermodynamics, heat must spontaneously flow from hot to cold systems. In quantum thermodynamics, the same law applies when considering multipartite product thermal st…
Entanglement dynamics of two modes coupled through a dissipative movable mirror in an optomechanical system
Bruno P. Schnepper, Danilo Cius, Fabiano M. Andrade
Nonclassical states are an important class of states in quantum mechanics, particularly for applications in quantum information theory. Optomechanical systems are invaluable platfo…
Unitary evolution for a two-level quantum system in fractional-time scenario
D. Cius, L. Menon, M. A. F. dos Santos +2
The time-evolution operator obtained from the fractional-time Schrödinger equation (FTSE) is said to be non-unitary since it does not preserve the norm of the vector state in time.…
Entanglement between uncoupled modes with time-dependent complex frequencies
D. Cius, G. M. Uhdre, A. S. M. de Castro +1
In this work we present the general unified description for the unitary time-evolution generated by time-dependent non-Hermitian Hamiltonians embedding the bosonic representations…
Superstatistical approach of the anomalous exponent for scaled Brownian motion
M. A. F. dos Santos, L. Menon Junior, D. Cius
Anomalous diffusion phenomenon is an intriguing process that tracer diffusion presents in numerous complex systems. Current experimental and theoretical investigations have reporte…
Mixed states driven by Non-Hermitian Hamiltonians of a nuclear spin ensemble
D. Cius, A. Consuelo-Leal, A. G. Araujo-Ferreira +1
We study the quantum dynamics of a non-interacting spin ensemble under the effect of a reservoir by applying the framework of the non-Hermitian Hamiltonian operators. Theoretically…
Enhancement of photon creation through the pseudo-Hermitian dynamical Casimir effect
D. Cius, F. M. Andrade, A. S. M. de Castro +1
We analyse here the pseudo-Hermitian Dynamical Casimir effect, proposing a non-Hermitian version of the effective Law's Hamiltonian used to describe the phenomenon. We verify that…
Effects of quantum deformation on the Jaynes-Cummings and anti-Jaynes-Cummings models
Gustavo M. Uhdre, Danilo Cius, Fabiano M. Andrade
The theory of non-Hermitian systems and the theory of quantum deformations have attracted a great deal of attention in the past decades. In general, non-Hermitian Hamiltonians are…
