Probing quantum scars and weak ergodicity breaking through quantum complexity

B Bhattacharjee, S Sur, P Nandy - Physical Review B, 2022 - APS
Scar states are special many-body eigenstates that weakly violate the eigenstate
thermalization hypothesis (ETH). Using the explicit formalism of the Lanczos algorithm …

Self-localized solitons of a q-deformed quantum system

C Bayındır, AA Altintas, F Ozaydin - Communications in Nonlinear Science …, 2021 - Elsevier
Beyond a pure mathematical interest, q-deformation is promising for the modeling and
interpretation of various physical phenomena. In this paper, we numerically investigate the …

Intermediate statistics: Addressing the thermoelectric properties of solids

AA Marinho, FA Brito, GM Viswanathan, CG Bezerra - Physical Review E, 2024 - APS
We study the thermodynamics of a crystalline solid by applying intermediate statistics
obtained by deforming known solid state models using the mathematics of q analogs. We …

q-Deformed three-level quantum logic

AA Altintas, F Ozaydin, C Bayındır - Quantum Information Processing, 2020 - Springer
Three-level information plays an important role in the quantum domain. However, q-
deformed three-level quantum logic is missing. Here, we address this problem and following …

Squeezing and nonclassicality of q-deformed superposition states

S Kannan, C Sudheesh - The European Physical Journal D, 2022 - Springer
We inquire into the nonclassical properties of the superposition of squeezed vacuum and
that of squeezed coherent states of a math-type q-deformed harmonic oscillator. The …

Dynamical Manifestation of Chaotic Behaviour in a q-Tsallis Harmonic Oscillator

R Boudjema - International Journal of Theoretical Physics, 2022 - Springer
Recently, the q-deformed coherent states based on the non-extensive thermodynamics
approach have been constructed (Chung et al.; Jagannathan and Khan; Bendjeffal et al.). In …

Wave packet dynamics of entangled q-deformed states

M Rohith, S Anupama… - Physica …, 2024 - xn--www-vt23b.iopscience.iop.org
This paper explores the wave packet dynamics of a math-type q-deformed field interacting
with atoms in a Kerr-type nonlinear medium. The primary focus is on the generation and …

Nonlinear dynamics of superposition of wavepackets

S Kannan, M Rohith, C Sudheesh - The European Physical Journal Plus, 2022 - Springer
We study nonlinear dynamics of superposition of quantum wavepackets in various systems
such as Kerr medium, Morse oscillator, and bosonic Josephson junction. The prime reason …

Quadrature operator eigenstates and energy eigenfunctions of f-deformed oscillators

S Anupama, A Pradeep, A Pal, S Chethil - Indian Journal of Physics, 2022 - Springer
