One-dimensional quantum many body systems with long-range interactions
Somnath Maity, Utso Bhattacharya, Amit Dutta
The presence of algebraically decaying long-range interactions may alter the critical as well as topological behaviour of a quantum many-body systems. However, when the interaction…
Temporal variation in the winding number due to dynamical symmetry breaking and associated transport in a driven SSH chain
Souvik Bandyopadhyay, Utso Bhattacharya, Amit Dutta
Considering a BDI symmetric one-dimensional SSH model, we explore the fate of the bulk topological invariant, namely, the winding number under a generic time dependent perturbation…
Fibonacci steady states in a driven integrable quantum system
Somnath Maity, Utso Bhattacharya, Amit Dutta +1
We study an integrable system that is reducible to free fermions by a Jordan-Wigner transformation which is subjected to a Fibonacci driving protocol based on two non-commuting Ham…
Dynamical Quantum Phase Transitions in Extended Toric-Code Models
Vatshal Srivastav, Utso Bhattacharya, Amit Dutta
We study the nonequilibrium dynamics of the extended toric code model (both ordered and disordered) to probe the existence of the dynamical quantum phase transitions (DQPTs). We sh…
The fate of current, residual energy and entanglement entropy in aperiodic driving of one dimensional Jordan Wigner integrable models
Somnath Maity, Utso Bhattacharya, Amit Dutta
We investigate the dynamics of two Jordan Wigner solvable models, namely, the one dimensional chain of hard-core bosons (HCB) and the one-dimensional transverse field Ising model u…
Exploring the possibilities of dynamical quantum phase transitions in the presence of a Markovian bath
Souvik Bandyopadhyay, Sudarshana Laha, Utso Bhattacharya +1
We explore the possibility of dynamical quantum phase transitions (DQPTs) occurring during the temporal evolution of a quenched transverse field Ising chain coupled to a particle l…
