Quantum-to-semiclassical Husimi dynamics of non-Hermitian localization transitions
Pallabi Chatterjee, Bhabani Prasad Mandal, Ranjan Modak
The localization transition in the Hermitian Aubry-André model is known to have a clear classical origin, with the critical point being exactly predictable from an analysis of cla…
Entanglement structure for finite system under dual-unitary dynamics
Gaurav Rudra Malik, Rohit Kumar Shukla, Sudhanva Joshi +2
The dynamics of quantum many-body systems in the chaotic regime are of particular interest due to the associated phenomena of information scrambling and entanglement generation wit…
Quantum memory and scrambling from the perspective of a classical neural network
Dimitrios Maroulakos, Andrzej Wal, Marcin Kowalik +4
Entropic uncertainty relations are universal quantifiers of fundamental uncertainties of quantum measurements and are widely discussed in the quantum metrology literature. Quantum…
Scaling of entanglement entropy and correlations in the variable-range extended Ising model
Harikrishnan K J, Debasis Sadhukhan, Amit Kumar Pal
We study the two-point correlation functions and the bipartite entanglement in the ground state of the exactly-solvable variable-range extended Ising model of qubits in the presenc…
Quantum phase transitions and entanglement entropy in a non-Hermitian Jaynes-Cummings model
Gargi Das, Aritra Ghosh, Bhabani Prasad Mandal
In this paper, we describe some interesting properties of a non-Hermitian Jaynes-Cummings model. For this particular model, it is known that the Hilbert space can be described by i…
Emergence of Hermitian topology from non-Hermitian knots
Gaurav Hajong, Ranjan Modak, Bhabani Prasad Mandal
The non-Hermiticity of the system gives rise to a distinct knot topology in the complex eigenvalue spectrum, which has no counterpart in Hermitian systems. In contrast, the singula…
