Order parameters and ground-state phase diagram of the interacting topological Su-Schrieffer-Heeger model with extended-range hoppings
Tsz Hin Hui, Pedro D. Sacramento, Wing Chi Yu
Topological insulators have attracted numerous attentions recent years, where the Su-Schrieffer-Heeger (SSH) model is one of the most studied models. While the interacting version…
Competition and coexistence of superconducting symmetries in -wave magnets
J. E. C. Carmelo, I. R. Pimentel, P. D. Sacramento
We investigate the interplay between unconventional magnetism and superconductivity in a model of a -wave magnet on a square lattice. Using a self-consistent Bogoliubov-de-Genne…
Multifractality and pre-thermalization in the quasi-periodically kicked Aubry-André-Harper model
Wen Chen, Pedro D. Sacramento, Rubem Mondaini
In a class of periodically driven systems, multifractal states in non-equilibrium conditions and robustness of dynamical localization when the driving is made aperiodic have receiv…
Zigzag materials: selective interchain couplings control the coexistence of one-dimensional physics and deviations from it
J. M. P. Carmelo, P. D. Sacramento, T. Stauber +1
The coexistence in the low-temperature spin-conducting phases of the zigzag materials BaCo2V2O8 and SrCo2V2O8 of one-dimensional (1D) physics with important deviations from it is n…
Quasidisorder Induced Topology
M. F. Madeira, P. D. Sacramento
We study the effects of quasidisorder and Anderson disorder on a two dimensional topological superconductor with an applied external magnetic field. The cases of a -wave superco…
Topological states in chiral electronic chains
P. D. Sacramento, M. F. Madeira
We consider the influence of topological phases, or their vicinity, on the spin density and spin polarization through a chiral chain. We show the quantization of the Berry phase in…
