Majorana Flat Bands in s-Wave Gapless Topological Superconductors
Shusa Deng, Gerardo Ortiz, Amrit Poudel +1
We demonstrate how the non-trivial interplay between spin-orbit coupling and nodeless -wave superconductivity can drive a fully gapped two-band topological insulator into a time…
Multiband s-wave topological superconductors: role of dimensionality and magnetic field response
Shusa Deng, Gerardo Ortiz, Lorenza Viola
We further investigate a class of time-reversal-invariant two-band s-wave topological superconductors introduced in Phys. Rev. Lett. 108, 036803 (2012). We show how, in the presenc…
Majorana modes in time-reversal invariant s-wave topological superconductors
Shusa Deng, Lorenza Viola, Gerardo Ortiz
We present a time-reversal invariant s-wave superconductor supporting Majorana edge modes. The multi-band character of the model together with spin-orbit coupling are key to realiz…
Dynamical critical scaling and effective thermalization in quantum quenches: the role of the initial state
Shusa Deng, Gerardo Ortiz, Lorenza Viola
We explore the robustness of universal dynamical scaling behavior in a quantum system near criticality with respect to initialization in a large class of states with finite energy.…
Anomalous non-ergodic scaling in adiabatic multicritical quantum quenches
Shusa Deng, Gerardo Ortiz, Lorenza Viola
We investigate non-equilibrium dynamical scaling in adiabatic quench processes across quantum multicritical points. Our analysis shows that the resulting power-law scaling depends…
Dynamical non-ergodic scaling in continuous finite-order quantum phase transitions
Shusa Deng, Gerardo Ortiz, Lorenza Viola
We investigate the emergence of universal dynamical scaling in quantum critical spin systems adiabatically driven out of equilibrium, with emphasis on quench dynamics which involve…
