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…
Dynamics of quantum Fisher and Wigner-Yanase skew information following a noisy quench
J. Naji, R. Jafari, Alireza Akbari +1
We study the effect of noise on the dynamics of the transverse-field Ising model quenched across a quantum critical point. To quantify two-spin correlations, we employ the quantum…
Anti Kibble-Zurek behavior in the quantum XY spin-1/2 chain driven by correlated noisy magnetic field and anisotropy
S. Sadeghizade, R. Jafari, A. Langari
In the non-adiabatic dynamics across a quantum phase transition, the Kibble-Zurek paradigm describes that the average number of topological defects is suppressed as a universal pow…
Entanglement generation and scaling from noisy quenches across a quantum critical point
R. Jafari, J. Naji, A. Langari +2
We study the impact of noise on the dynamics of entanglement in the transverse-field Ising chain, with the field quenched linearly across one or both of the quantum critical points…
Dynamics of Steered Quantum Coherence and Magic Resource under Sudden Quench
Saeid Ansari, Alireza Akbari, R. Jafari
We explore the dynamics of l_1-norm of steered quantum coherence (SQC), steered quantum relative entropy (SQRE), and magic resource quantifier (QRM) in the one-dimensional XY spin…
