Non-linear dynamical response of interacting bosons to synthetic electric field
Arko Roy, Soumya Bera, Kush Saha
We theoretically study the non-linear response of interacting neutral bosonic gas in a synthetically driven one-dimensional optical lattice. In particular, we examine the bosonic a…
Interacting bosons in two-dimensional lattices with localized dissipation
Arko Roy, Kush Saha
Motivated by the recent experiment [Takafumi Tomita \emph{et al.}, Sci. Adv. {\bf 3}, (2017)], we study the dynamics of interacting bosons in a two-dimensional optical lattice with…
Fibonacci optical lattices for tunable quantum quasicrystals
Kevin Singh, Kush Saha, Siddharth A. Parameswaran +1
We describe a quasiperiodic optical lattice, created by a physical realization of the abstract cut-and-project construction underlying all quasicrystals. The resulting potential is…
Quantum phase transition of ultracold bosons in the presence of a non-Abelian synthetic gauge field
T. Grass, K. Saha, K. Sengupta +1
We study the Mott phases and the superfluid-insulator transition of two-component ultracold bosons on a square optical lattice in the presence of a non-Abelian synthetic gauge fiel…
