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…
Critical phase boundaries of static and periodically kicked long-range Kitaev chain
Utso Bhattacharya, Somnath Maity, Amit Dutta +1
We study the static and dynamical properties of a long-range Kitaev chain, i.e., a -wave superconducting chain in which the superconducting pairing decays algebraically as $1/l^…
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…
Role of topology on the work distribution function of a quenched Haldane model of graphene
Sourav Bhattacharjee, Utso Bhattacharya, Amit Dutta
We investigate the effect of equilibrium topology on the statistics of non-equilibrium work performed during the subsequent unitary evolution, following a sudden quench of the Seme…
