Light-induced fractional quantum Hall phases in graphene
Areg Ghazaryan, Tobias Graß, Michael J. Gullans +2
We show how to realize two-component fractional quantum Hall phases in monolayer graphene by optically driving the system. A laser is tuned into resonance between two Landau levels…
Hybrid annealing using a quantum simulator coupled to a classical computer
Tobias Graß, Maciej Lewenstein
Finding the global minimum in a rugged potential landscape is a computationally hard task, often equivalent to relevant optimization problems. Simulated annealing is a computationa…
Proximity effects in cold atom artificial graphene
Tobias Grass, Ravindra W. Chhajlany, Leticia Tarruell +2
Cold atoms in an optical lattice with brick-wall geometry have been used to mimic graphene, a two-dimensional material with characteristic Dirac excitations. Here we propose to bri…
Modified spin-wave theory and spin liquid behavior of cold bosons on an inhomogeneous triangular lattice
Alessio Celi, Tobias Grass, Andrew J. Ferris +5
Ultracold bosons in a triangular lattice are a promising candidate for observing quantum spin liquid behavior. Here we investigate, for such system, the role of a harmonic trap giv…
