Dynamical generation of Floquet Majorana flat bands in s-wave superconductors
Amrit Poudel, Gerardo Ortiz, Lorenza Viola
We present quantum control techniques to engineer flat bands of symmetry-protected Majorana edge modes in s-wave superconductors. Specifically, we show how periodic control may be…
Nonadiabatic Dynamics of a Dissipative Two-level System
Canran Xu, Amrit Poudel, Maxim G. Vavilov
We study the dynamics of a two-level system described by a slowly varying Hamiltonian and weakly coupled to the Ohmic environment. We follow the Bloch--Redfield perturbative approa…
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…
