Majorana zero modes in a magnetic and superconducting hybrid vortex
Vedangi Pathak, Sayak Dasgupta, Marcel Franz
We propose and investigate a new platform for the realization of Majorana zero modes in a thin-film heterostructure composed of an easy-plane ferromagnet and a superconductor with…
Strain tuning the magnetic and transport properties of MnGe
Sayak Dasgupta
The kagome lattice antiferromagnet MnGe has a local hexagonal symmetry with a 120 ordered ground state. This non-colinear ground state engenders a strong anomalous Hall…
Tuning the Hall response of a noncollinear antiferromagnet via spin-transfer torques and oscillating magnetic fields
Sayak Dasgupta, Oleg A. Tretiakov
The kagome lattice antiferromagnets MnX(= Sn, Ge) have a noncollinear 120 ordered ground state, which engenders a strong anomalous Hall response. It has been shown that…
Zeeman term for the Néel vector in a two sublattice antiferromagnet using Dzyaloshinsky-Moriya interaction and magnetic field
Sayak Dasgupta, Ji Zou
We theoretically investigate the dynamics of solitons in two sublattice antiferromagnets under external perturbations, focusing on the effect of Dzyaloshinsky-Moriya (DM) interacti…
Realizing Su-Schrieffer-Heeger topological edge states in Rydberg-atom synthetic dimensions
S. K. Kanungo, J. D. Whalen, Y. Lu +5
We demonstrate a platform for synthetic dimensions based on coupled Rydberg levels in ultracold atoms, and we implement the single-particle Su-Schrieffer-Heeger (SSH) Hamiltonian.…
Ambipolar magneto-optical response of ultra-low carrier density topological insulators
Dipanjan Chaudhuri, Maryam Salehi, Sayak Dasgupta +5
We have investigated the THz range magneto-optical response of ultralow carrier density films of SbTe using time-domain THz polarimetry. Undoped SbTe has a chemical…
