Quantum spin liquids bootstrapped from Ising criticality in Rydberg arrays
Kevin Slagle, Yue Liu, David Aasen +5
Arrays of Rydberg atoms constitute a highly tunable, strongly interacting venue for the pursuit of exotic states of matter. We develop a new strategy for accessing a family of frac…
Microscopic characterization of Ising conformal field theory in Rydberg chains
Kevin Slagle, David Aasen, Hannes Pichler +5
Rydberg chains provide an appealing platform for probing conformal field theories (CFTs) that capture universal behavior in a myriad of physical settings. Focusing on a Rydberg cha…
Complex density wave orders and quantum phase transitions in a model of square-lattice Rydberg atom arrays
Rhine Samajdar, Wen Wei Ho, Hannes Pichler +2
We describe the zero-temperature phase diagram of a model of a two-dimensional square-lattice array of neutral atoms, excited into Rydberg states and interacting via strong van der…
Numerical study of the chiral quantum phase transition in one spatial dimension
Rhine Samajdar, Soonwon Choi, Hannes Pichler +2
Recent experiments on a one-dimensional chain of trapped alkali atoms [arXiv:1707.04344] have observed a quantum transition associated with the onset of period-3 ordering of pumped…
An entropy perspective on the thermal crossover in a fermionic Hubbard chain
Lars Bonnes, Hannes Pichler, Andreas M. Läuchli
We study the Renyi entropy in the finite temperature crossover regime of a Hubbard chain using quantum Monte Carlo. The ground state entropy has characteristic features such as a l…
