Two-body repulsive bound pairs in multi-body interacting Bose-Hubbard model
Suman Mondal, Augustine Kshetrimayum, Tapan Mishra
We study the system of multi-body interacting bosons on a two dimensional optical lattice and analyze the formation of bound bosonic pairs in the context of the Bose-Hubbard model.…

Simulation methods for open quantum many-body systems
Hendrik Weimer, Augustine Kshetrimayum, Román Orús
Coupling a quantum many-body system to an external environment dramatically changes its dynamics and offers novel possibilities not found in closed systems. Of special interest are…
