Kibble--Zurek Mechanism and Defect Freezing in Imbalanced-Pairing Kitaev Models
R. Jafari, Alireza Akbari, Shukhrat Mardonov +1
We investigate driven dynamics across critical and exceptional points in the one- and two-dimensional imbalanced-pairing Kitaev models using both the wave-function normalization ap…
Dissipation-Induced Deviations from Kibble-Zurek Scaling in Non-Hermitian Quantum Annealing
H. Najafzadeh, S. Sadeghizade, R. Jafari +1
We revisit the quantum annealing problem in the non-Hermitian transverse-field Ising model. We determine, both analytically and numerically, the intrinsic transition probabilities…
Separation of the Kibble-Zurek Mechanism from Quantum Criticality
R. Jafari, Alireza Akbari
When a system is swept through a quantum critical point (QCP), the Kibble-Zurek mechanism predicts that the average number of topological defects follows a universal power-law scal…
Topological Defects from Quantum Reset Dynamics
R. Jafari, Henrik Johannesson, Sebastian Eggert
We analyze mechanisms for universal out-of-equilibrium dynamics near criticality by exploring the effect of randomized quantum resetting (QR) under a finite-time quench across a qu…
