Realization of a Synthetic Hall Torus with a Spinor Bose-Einstein Condensate

T. -H. Chien, S. -C. Wu, Y. -H. Su +5

We report the first experimental realization of a synthetic Hall torus using a spinor Bose-Einstein condensate confined in a ring-shaped trap with in situ imaging. By cyclically co…

Harmonic Control of Dynamical Freezing in Programmable Rydberg Atom Arrays

Madhumita Sarkar, Ben Zindorf, Bhaskar Mukherjee +2

Periodic driving enables the engineering of complex quantum matter, yet in interacting systems it generically leads to energy absorption, which limits the lifetime of the engineere…

Doublon-Holon Pairing State in Photodoped Mott Insulators

Ryota Ueda, Madhumita Sarkar, Zala Lenarčič +3

We demonstrate the existence of an unconventional pairing state in photodoped Mott insulators on ladder and quasi-two-dimensional geometries, characterized by quasi-long-range doub…

Re-entrant localization induced by short-range hopping in the fractal Rosenzweig-Porter Model

Roopayan Ghosh, Madhumita Sarkar, Ivan M. Khaymovich

Typically, metallic systems localized under strong disorder exhibit a transition to \imk{delocalization} %finite conduction as kinetic terms increase. In this work, we reveal the o…

Scar-induced imbalance in staggered Rydberg ladders

Mainak Pal, Madhumita Sarkar, K. Sengupta +1

We demonstrate that the kinematically-constrained model of Rydberg atoms on a two-leg ladder with staggered detuning, , has quantum many-body scars (QMBS) in its spectr…
