Quantum order-by-disorder induced phase transition in Rydberg ladders with staggered detuning

Madhumita Sarkar, Mainak Pal, Arnab Sen +1

${}^{87}\mathrm{Rb}$ atoms are known to have long-lived Rydberg excited states with controllable excitation amplitude (detuning) and strong repulsive van der Waals interaction $V_{{\bf…
