Effects of surface potentials on Goos-Haenchen and Imbert-Fedorov shifts in Weyl semimetals
Ninad Kailas Dongre, Krishanu Roychowdhury
Weyl semimetals exhibit exotic transport responses, among which, recently Goos-Haenchen (GH) and Imbert-Fedorov (IF) effects have received a revived attention, which are, otherwise…
Topology in non-linear mechanical systems
Po-Wei Lo, Krishanu Roychowdhury, Bryan Gin-ge Chen +3
Many advancements have been made in the field of topological mechanics. The majority of the works, however, concerns the topological invariant in a linear theory. We, in this work,…
Spin-polarized voltage probes for helical edge state: a model study
Vivekananda Adak, Krishanu Roychowdhury, Sourin Das
Theoretical models of a spin-polarized voltage probe (SPVP) tunnel-coupled to the helical edge states (HES) of a quantum spin Hall system (QSHS) are studied. Our first model of the…
Entanglement dualities in supersymmetry
Robert H. Jonsson, Lucas Hackl, Krishanu Roychowdhury
We derive a general relation between the bosonic and fermionic entanglement in the ground states of supersymmetric quadratic Hamiltonians. For this, we construct canonical identifi…
