Discrete-time quantum walks with energy-dependent coins
Alana Spak dos Santos, Thiago T. Tsutsui, Fabiano M. Andrade
In this work, we extend the scattering quantum walk (SQW) framework to a lattice of energy-dependent point interactions. This yields, within the coined quantum walk (CQW) formalism…
Continuous limit of the square well problem in quantum mechanics
Matheus D. Moro, Thiago T. Tsutsui, Antonio S. M. de Castro +1
The free-particle and square-well potentials are two of the most emblematic problems in quantum mechanics, illustrating essential concepts such as matter waves, energy quantization…
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…
Optical perspective on the time-dependent Dirac oscillator
Thiago T. Tsutsui, Alison A. Silva, Antonio S. M. de Castro +1
The Dirac oscillator is a relativistic quantum system, characterized by its linearity in both position and momentum. Moreover, considering and dimensions, the s…
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…
The Dirac equation: historical context, comparisons with the Schrödinger and Klein-Gordon equations, and elementary consequences
Thiago T. Tsutsui, Edilberto O. Silva, Antonio S. M. de Castro +1
This paper offers educational insight into the Dirac equation, examining its historical context and contrasting it with the earlier Schrödinger and Klein-Gordon (KG) equations. The…
Reproducing the effects of quantum deformation in the undeformed Jaynes-Cummings model
Thiago T. Tsutsui, Antonio S. M. de Castro, Fabiano M. Andrade
In the Jaynes-Cummings (JC) model, the time dependence in the coupling parameter allows changes in the forms of the Rabi oscillations. In the inverse problem approach (IPA), the ti…
