Confinement and lack of thermalization after quenches in the bosonic Schwinger model
Titas Chanda, Jakub Zakrzewski, Maciej Lewenstein +1
We excite the vacuum of a relativistic theory of bosons coupled to a gauge field in 1+1 dimensions (bosonic Schwinger model) out of equilibrium by creating a spatially separ…
Time dynamics with matrix product states: Many-body localization transition of large systems revisited
Titas Chanda, Piotr Sierant, Jakub Zakrzewski
We compare accuracy of two prime time evolution algorithms involving Matrix Product States - tDMRG (time-dependent density matrix renormalization group) and TDVP (time-dependent va…
Response of macroscopic and microscopic dynamical quantifiers to the quantum critical region
Stav Haldar, Saptarshi Roy, Titas Chanda +1
At finite temperatures, the quantum critical region (QCR) emerges as a consequence of the interplay between thermal and quantum fluctuations. We seek for suitable physical quantiti…
Enhancement in performance of quantum battery by ordered and disordered interactions
Srijon Ghosh, Titas Chanda, Aditi Sen De
Considering ground state of a quantum spin model as the initial state of the quantum battery, we show that both ordered and disordered interaction strengths play a crucial role to…
