Ising models of quantum frustration
R. Moessner, S. L. Sondhi
We report on a systematic study of two dimensional, periodic, frustrated Ising models with a quantum dynamics introduced via a transverse magnetic field. The systems studied are th…
Breakdown of Conformal Invariance at Strongly Random Critical Points
M. B. Hastings, S. L. Sondhi
We consider the breakdown of conformal and scale invariance in random systems with strongly random critical points. Extending previous results on one-dimensional systems, we provid…
An RVB phase in the triangular lattice quantum dimer model
R. Moessner, S. L. Sondhi
We study the quantum dimer model on the triangular lattice, which is expected to describe the singlet dynamics of frustrated Heisenberg models in phases where valence bond configur…
Sliding Phases via Magnetic Fields
S. L. Sondhi, Kun Yang
We show that three dimensional "sliding" analogs of the Kosterlitz-Thouless phase, in stacked classical two-dimensional XY models and quantum systems of coupled Luttinger Liquids,…
The fractional quantum Hall effect in infinite layer systems
J. D. Naud, Leonid P. Pryadko, S. L. Sondhi
Stacked two dimensional electron systems in transverse magnetic fields exhibit three dimensional fractional quantum Hall phases. We analyze the simplest such phases and find novel…
Notes on Infinite Layer Quantum Hall Systems
J. D. Naud, Leonid P. Pryadko, S. L. Sondhi
We study the fractional quantum Hall effect in three dimensional systems consisting of infinitely many stacked two dimensional electron gases placed in transverse magnetic fields.…
