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…
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…
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…
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…
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…
Dynamics of decoherence in a noisy driven environment
R. Jafari, A. Asadian, M. Abdi +1
We analyze the decoherence dynamics of a central spin coupled to a spin chain with a time-dependent noisy magnetic field, focusing on how noise influences the system's decoherence.…
Competition of long-range interactions and noise at ramped quench dynamical quantum phase transition: The case of the long-range pairing Kitaev chain
R. Baghran, R. Jafari, A. Langari
The nonequilibrium dynamics of long-range pairing Kitaev model with noiseless/noisy linear time dependent chemical potential, is investigated in the frame work of dynamical quantum…
Scaling and Universality at Ramped Quench Dynamical Quantum Phase Transition
Sara Zamani, J. Naji, R. Jafari +1
The nonequilibrium dynamics of a periodically driven extended XY model, in the presence of linear time dependent magnetic filed, is investigated using the notion of dynamical quant…
Geometrically Frustrated Anisotropic Four-Leg Spin- Nanotube
R. Jafari, Saeed Mahdavifar, Alireza Akbari
We develop a real space quantum renormalization group (QRG) to explore a frustrated anisotropic four-leg spin-1/2 nanotube in the thermodynamic limit. We obtain the phase diagram,…
