Generating discrete time crystals through optimal control
Mrutyunjaya Sahoo, Rahul Ghosh, Bandita Das +3
In this work we use optimal control to generate Discrete Time Crystals (DTC) in generic many-body quantum systems. We define appropriate cost functions, which, when optimized, resu…

Spin-imbalance induced buried topological edge currents in Mott \& topological insulator heterostructures
Rahul Ghosh, Subhajyoti Pal, Kush Saha +1
We theoretically investigate the heterostructure between a ferrimagnetic Mott insulator and a time-reversal invariant topological band insulator on the two-dimensional Lieb lattice…
