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…
Anderson localization via Peierls phase modulation
Arpita Goswami, Pallabi Chatterjee, Ranjan Modak +1
We investigate a two leg ladder system subjected to an external magnetic field. In the absence of a magnetic field, the system is described by a clean tight binding model, with no…
Subsystem localization in a two-leg ladder system
Arpita Goswami, Pallabi Chatterjee, Ranjan Modak +1
We consider a ladder system where one leg, referred to as the ``bath", is governed by an Aubry-André (AA) type Hamiltonian, while the other leg, termed the ``subsystem", follows a…
Measurement-induced phase transition in periodically driven free-fermionic systems
Pallabi Chatterjee, Ranjan Modak
It is well known that unitary evolution tends to increase entanglement, whereas continuous monitoring counteracts this growth by pinning the wavefunction trajectories to the eigens…
