Periodically driven integrable systems with long-range pair potentials
Sourav Nandy, K. Sengupta, Arnab Sen
We study periodically driven closed systems with a long-ranged Hamiltonian by considering a generalized Kitaev chain with pairing terms which decay with distance as a power law cha…
Ramp and periodic dynamics across non-Ising critical points
Roopayan Ghosh, Arnab Sen, K. Sengupta
We study ramp and periodic dynamics of ultracold bosons in an one-dimensional (1D) optical lattice which supports quantum critical points separating a uniform and a or …
Duality between the deconfined quantum-critical point and the bosonic topological transition
Yan Qi Qin, Yuan-Yao He, Yi-Zhuang You +5
Recently significant progress has been made in -dimensional conformal field theories without supersymmetry. In particular, it was realized that different Lagrangians may be…
Aperiodically driven integrable systems and their emergent steady states
Sourav Nandy, Arnab Sen, Diptiman Sen
Does a closed quantum many-body system that is continually driven with a time-dependent Hamiltonian finally reach a steady state? This question has only recently been answered for…
