Quantum Annealing in Sherrington-Kirkpatrick Spin Glass in Presence of Time-Dependent Longitudinal Field
Atanu Rajak, Bikas K Chakrabarti
Motivated by the recent development of quantum technology using quantum annealing technique and the recent works on the static properties of the Sherrington-Kirkpatrick (SK) spin g…

Possible Ergodic-nonergodic regions in the quantum Sherrington-Kirkpatrick spin glass model and quantum annealing
Sudip Mukherjee, Atanu Rajak, Bikas K Chakrabarti
We explore the behavior of order parameter distribution of quantum Sherrington-Kirkpatrick model in the spin glass phase using Monte Carlo technique for the effective Suzuki-Trotte…

Study of Loschmidt Echo for two-dimensional Kitaev model
Shraddha Sharma, Atanu Rajak
In this paper, we study the Loschmidt Echo (LE) of a two-dimensional Kitaev model residing on a honeycomb lattice which is chosen to be an environment that is coupled globally to a…
