Exactly Solvable 1D Quantum Models with Gamma Matrices
Yash Chugh, Kusum Dhochak, Uma Divakaran +2
In this paper, we write exactly solvable generalizations of 1-dimensional quantum XY and Ising-like models by using -dimensional Gamma () matrices as the degrees of freedom…
Adiabatic dynamics of quasiperiodic transverse Ising model
Revathy B. S., Uma Divakaran
We study the non-equilibrium dynamics due to slowly taking a quasiperiodic Hamiltonian across its quantum critical point. The special quasiperiodic Hamiltonian that we study here h…
Sudden quenches in quasiperiodic Ising model
Uma Divakaran
We present here the non-equilibrium dynamics of the recently studied quasiperiodic Ising model. The zero temperature phase diagram of this model mainly consists of three phases, wh…
Tuning the presence of dynamical phase transitions in a generalized spin chain
Uma Divakaran, Shraddha Sharma, Amit Dutta
We study an integrable spin chain with three spin interactions and the staggered field () while the latter is quenched either slowly (in a linear fashion in time () as …
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, ) of a one-dimensional transverse Ising chain with nearest neighbor ferromagentic interactions acros…
Effect of double local quenches on Loschmidt echo and entanglement entropy of a one-dimensional quantum system
Atanu Rajak, Uma Divakaran
We study the effect of two simultaneous local quenches on the evolution of Loschmidt echo and entanglement entropy of a one dimensional transverse Ising model. In this work, one of…
