Tuning the presence of dynamical phase transitions in a generalized $X Y$ spin chain

Uma Divakaran, Shraddha Sharma, Amit Dutta

We study an integrable spin chain with three spin interactions and the staggered field ( $λ$ ) while the latter is quenched either slowly (in a linear fashion in time ( $t$ ) as $t / τ$ …

Slow quenches in a quantum Ising chain; dynamical phase transitions and topology

Shraddha Sharma, Uma Divakaran, Anatoli Polkovnikov +1

We study the slow quenching dynamics (characterized by an inverse rate, $τ^{- 1}$ ) of a one-dimensional transverse Ising chain with nearest neighbor ferromagentic interactions acros…
