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…
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…
Noise-Affected Dynamical Quantum Phase Transitions
R. Jafari, Alireza Akbari, Mehdi Biderang +1
We investigate the effects of uncorrelated noise on dynamical quantum phase transitions (DQPTs) in fermionic two-band models following a quantum ramp across critical points. We con…
Scaling and Universality at Noisy Quench Dynamical Quantum Phase Transitions
Saeid Ansari, R. Jafari, Alireza Akbari +1
Dynamical quantum phase transitions (DQPTs) have been studied in the extended XY model under both noiseless and noisy linear driven staggered field cases. In the time-independent s…
Dynamical Phase diagram of the Quantum Ising model with Cluster Interaction Under Noisy and Noiseless Driven field
Sasan Kheiri, R. Jafari, S. Mahdavifar +2
In most lattice models, gap closing typically occurs at high-symmetry points in the Brillouin zone. In the transverse field Ising model with cluster interaction, besides the gap cl…
