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…
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…
Solitons in a discrete model of chiral liquid crystals with competing interactions
Alain M. Dikandé, Bernard Y. Nyanga, S. E. Mkam Tchouobiap
Chiral liquid crystals exhibit in-plane spontaneous polarizations, however in their smectic phase the primary order parameter is a tilt vector associated with molecular rotations a…
Finite-size and Fluctuation Effects on Phase Transition and Critical Phenomena using Mean-Field Approach Based on Renormalized Model: I. Theory
R. M. Keumo Tsiaze, S. E. Mkam Tchouobiap, A. J. Fotué +4
An investigation of the spatial fluctuations and their manifestations in the vicinity of the quantum critical point within the framework of the renormalized theory is propo…
