Realizing the Frenkel-Kontorova model with Rydberg-dressed atoms

We propose a method to realize the Frenkel-Kontorova model using an array of Rydberg-dressed atoms. Our platform can be used to study this model with a range of realistic interatomic potentials. In particular, we concentrate on two types of interaction potentials: A springlike potential and a repulsive long-range potential. We numerically calculate the phase diagram for such systems and characterize the Aubry-type and commensurate-incommensurate phase transitions. Experimental realizations of this system are also discussed.
