- Abstract: The Landau-Ginzburg-Wilson theory of phase transitions precludes a continuous
transition between two phases that spontaneously break distinct symmetries.
However, quantum mechanical effects can intertwine the symmetries, giving rise
to an exotic phenomenon called deconfined quantum criticality (DQC). In this
work, we study the ground state phase diagram of a one-dimensional array of
individually trapped neutral atoms interacting strongly via Rydberg states, and
demonstrate through extensive numerical simulations that it hosts a variety of
symmetry-breaking phases and their transitions including DQC. We show how an
enlarged, emergent continuous symmetry arises at the DQCs, which can be
experimentally observed in the joint distribution of two distinct order
parameters, obtained within measurement snapshots in the standard computational
basis. Our findings highlight quantum simulators of Rydberg atoms not only as
promising platforms to experimentally realize such exotic phenomena, but also
as unique ones allowing access to physical properties not obtainable in
traditional experiments.
