Generation of renormalized quadratic coefficient in Landau theory: Implications for specific-heat jump calculations in high-temperature superconductors

Feulefack Ornela Claire, Tsague Fotio Carlos, Keumo Tsiaze Roger Magloire +4

In this work, Landau's theory is revisited by renormalizing quadratic coefficients derived from nonlinear polynomial equations to account for system dimensionality. In this respect…

Constructing Barut-Girardello coherent states for the isotonic oscillator in the DOOT approach

Messan Médard Akouetegan, Isiaka Aremua, Mahouton Norbert Hounkonnou

In this work, we study the quantum system of the isotonic oscillator from the perspective of the diagonal operator ordering technique (DOOT). Within this framework, we construct th…

Confinement-Tunable Synthetic Gauge Fields and Floquet Topological Phenomena in a Driven Quantum Wire Qubit

Feulefack Ornela Claire, Dongmo Tedo Lynsia Saychele, Danga Jeremie Edmond +6

Theoretical analysis demonstrates that a spin qubit in a parabolic quantum wire, when driven by a bichromatic field, exhibits a confinement-tunable synthetic gauge field leading to…

Induced phase transitions and spontaneous symmetry breaking based on the renormalized Ginzburg-Landau theory

Feulefack Ornela Claire, Tsague Fotio Carlos, Keumo Tsiaze Roger Magloire +2

In this study, we present theoretical investigations of phase transitions and critical phenomena in materials through the lens of second-order Ginzburg-Landau theory, in conjunctio…
