Abstract of the talk:
In this talk, we are going to provide a pedagogical introduction to the physics of a chain of ultracold Rydberg atoms. This will be followed by a discussion of their dynamical properties and the role played by a special class of states, quantum scars, in shaping their details. Finally, we shall discuss such systems in the presence of a periodic drive and show that the drive frequency can be used to tune their ergodicity property. In addition, the driven systems show several phenomena such as dynamical freezing and sub-thermal steady states. We shall discuss this and chart out experiments which can test these theoretical predictions.
