Ramp and periodic dynamics across non-Ising critical points
Roopayan Ghosh, Arnab Sen, K. Sengupta
We study ramp and periodic dynamics of ultracold bosons in an one-dimensional (1D) optical lattice which supports quantum critical points separating a uniform and a or …

Magnetization induced dynamics of a Josephson junction coupled to a nanomagnet
Roopayan Ghosh, Moitri Maiti, Yury M. Shukrinov +1
We study the superconducting current of a Josephson junction (JJ) coupled to an external nanomagnet driven by a time dependent magnetic field both without and in the presence of an…
