Dynamical phase transitions at finite temperature from fidelity and interferometric Loschmidt echo induced metrics
Bruno Mera, Chrysoula Vlachou, Nikola Paunković +2
We study finite-temperature Dynamical Quantum Phase Transitions (DQPTs) by means of the fidelity and the interferometric Loschmidt Echo (LE) induced metrics. We analyse the associa…
Localization and oscillations of Majorana fermions in a two-dimensional electron gas coupled with -wave superconductors
Laura Ortiz, Santiago Varona, Oscar Viyuela +1
We study the localization and oscillation properties of the Majorana fermions that arise in a two-dimensional electron gas (2DEG) with spin-orbit coupling (SOC) and a Zeeman field…
Linked cluster expansions for open quantum systems on a lattice
Alberto Biella, Jiasen Jin, Oscar Viyuela +3
We propose a generalization of the linked-cluster expansions to study driven-dissipative quantum lattice models, directly accessing the thermodynamic limit of the system. Our metho…
Chiral Topological Superconductors Enhanced by Long-Range Interactions
Oscar Viyuela, Liang Fu, Miguel Angel Martin-Delgado
We study the phase diagram and edge states of a two-dimensional p-wave superconductor with long-range hopping and pairing amplitudes. New topological phases and quasiparticles diff…
