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…

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…

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.…
