Quantum sensing with discrete time crystals in the Lipkin-Meshkov-Glick Model
Rahul Ghosh, Bandita Das, Victor Mukherjee
Quantum phase transitions have been shown to be highly beneficial for quantum sensing, owing to diverging quantum Fisher information close to criticality. In this work we consider…
Stabilizing boundary time crystals through Non-markovian dynamics
Bandita Das, Rahul Ghosh, Victor Mukherjee
We study Boundary time crystals (BTCs) in the presence of non-Markovian dynamics. In contrast to BTCs observed in earlier works in the Markovian regime, we show that non-Markovian…
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…
Discrete time crystals in the presence of non-Markovian dynamics
Bandita Das, Noufal Jaseem, Victor Mukherjee
We study discrete time crystals (DTCs) in periodically driven quantum systems, in the presence of non-Markovian dissipation. In contrast to DTCs observed in earlier works in the pr…
