Floquet Gauge Pumps as Sensors for Spectral Degeneracies Protected by Symmetry or Topology
Abhishek Kumar, Gerardo Ortiz, Philip Richerme +1
We introduce the concept of a Floquet gauge pump whereby a dynamically engineered Floquet Hamiltonian is employed to reveal the inherent degeneracy of the ground state in interacti…
A thermodynamic probe of the topological phase transition in epitaxial graphene based Floquet topological insulator
Abhishek Kumar, Colin Benjamin
One can use light to tune certain materials, from a trivial to a topological phase. A prime example of such materials, classified as Floquet topological insulators (FTI), is epitax…
Quasiparticle and Nonquasiparticle Transport in Doped Quantum Paraelectrics
Abhishek Kumar, Vladimir I. Yudson, Dmitrii L. Maslov
Charge transport in doped quantum paralectrics (QPs) presents a number of puzzles, including a pronounced regime in the resistivity. We analyze charge transport in a QP withi…
Non-Markovian resonance fluorescence
Abhishek Kumar
We derive a general formula for the non-Markovian fluorescence spectrum of a multi-level system interacting with a bosonic environment. To this end, we apply linear-response theory…
