Amplified Memory and Finite-Time Regularity in Driven Non-Hermitian Systems
H. Yavartanoo, R. Jafari, Alireza Akbari
We study the roles of broken spectra and exceptional points in finite-time driven non-Hermitian fermionic dynamics. We compute the Nambu biorthogonal correlation matrix for this pu…
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…
Dynamical Quantum Phase Transitions in a Pseudo-Hermitian Hamiltonian: The Imbalanced-Pairing Kitaev Model
R. Jafari, Alireza Akbari, Shukhrat Mardonov +1
Although parity-time (PT)-symmetric Hamiltonians are often associated with real energy spectra, PT symmetry is neither a sufficient nor a necessary condition for a real spectrum. M…
Reply to Comment on "Scaling and universality at noisy quench dynamical quantum phase transitions"
S. Ansari, R. Jafari, A. Akbari +1
The Comment by J. Sirker [arXiv:2511.16509] raises an important issue concerning dynamical quantum phase transitions (DQPTs) in noisy and mixed-state dynamics, namely that the exte…
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…
Scaling and Universality at Noise-Affected Non-Equilibrium Spin Correlation Functions
R. Jafari, Alireza Akbari
We investigate scaling and universality in nonequilibrium spin correlation functions in the presence of uncorrelated noise. In the absence of noise, spin correlation functions exhi…
Quantum Correlation Dynamics Subjected to Quantum Reset-Driven Environment
R. Jafari, Ali Asadian, Mehdi Biderang +1
We study two central qubits interacting with a transverse-field Ising chain that serves as their environment. The environment is driven linearly in time across its quantum critical…
