Biot-Savart correlations in layered superconductors
K. S. Raman, V. Oganesyan, S. L. Sondhi
We discuss the superconductor to normal phase transition in an infinite-layered type-II superconductor in the limit where the Josephson coupling between layers is negligible. We mo…
Dzyaloshinskii-Moriya interactions in valence bond systems
Mayra Tovar, Kumar S. Raman, Kirill Shtengel
We investigate the effect of Dzyaloshinskii-Moriya interactions on the low temperature magnetic susceptibility for a system whose low energy physics is dominated by short-range val…
Quantum dimer models
R. Moessner, K. S. Raman
These lecture notes aim to provide a self-contained, pedagogical introduction to the physics of local constraints, fractionalisation and topological liquids organised around the Ro…
Quantum dimer models and exotic orders
K. S. Raman, E. Fradkin, R. Moessner +2
We discuss how quantum dimer models may be used to provide "proofs of principle" for the existence of exotic magnetic phases in quantum spin systems.
Topological phases and topological entropy of two-dimensional systems with finite correlation length
Stefanos Papanikolaou, Kumar S. Raman, Eduardo Fradkin
We elucidate the topological features of the entanglement entropy of a region in two dimensional quantum systems in a topological phase with a finite correlation length . Firstl…
Devil's staircases, quantum dimer models, and stripe formation in strong coupling models of quantum frustration
S. Papanikolaou, K. S. Raman, E. Fradkin
We construct a two-dimensional microscopic model of interacting quantum dimers that displays an infinite number of periodic striped phases in its T=0 phase diagram. The phases form…
