Phases and collective modes of Rydberg atoms in an optical lattice
K. Saha, S. Sinha, K. Sengupta
We chart out the possible phases of laser driven Rydberg atoms in the presence of a hypercubic optical lattice. We define a pseudospin degree of freedom whose up(down) components c…

Bethe ansatz description of edge-localization in the open-boundary XXZ spin chain
Vincenzo Alba, Kush Saha, Masudul Haque
At large values of the anisotropy Δ, the open-boundary Heisenberg spin-1/2 chain has eigenstates displaying localization at the edges. We present a Bethe ansatz description of this…
