Diverse tunable dynamics of two quantum random walkers
Shrabanti Dhar, Abdul Khaleque, Tushar Kanti Bose
Quantum walk research has mainly focused on evolutions due to repeated applications of time-independent unitary coin operators. However, the idea of controlling the single particle…
Measurement-Induced Phase Transition in a Quantum Spin System
Shrabanti Dhar, Subinay Dasgupta
Suppose a quantum system starts to evolve under a Hamiltonian from some initial state. When for the first time, will an observable attain a preassigned value? To answer this questi…
Detection of a quantum particle on a lattice under repeated projective measurements
Shrabanti Dhar, Subinay Dasgupta, Abhishek Dhar +1
We consider a quantum particle, moving on a lattice with a tight-binding Hamiltonian, which is subjected to measurements to detect it's arrival at a particular chosen set of sites.…
Quantum time of arrival distribution in a simple lattice model
Shrabanti Dhar, Subinay Dasgupta, Abhishek Dhar
Imagine an experiment where a quantum particle inside a box is released at some time in some initial state. A detector is placed at a fixed location inside the box and its clicking…
