Field theory for generalized Shastry-Sutherland models
David Carpentier, Leon Balents
We consider the bosonic dimer representation for Generalized Shastry-Sutherland models that have the same symmetries as the original Shastry-Sutherland model and preserve the exact…
Nonequilibrium Steady States of Driven Periodic Media
Leon Balents, M. Cristina Marchetti, Leo Radzihovsky
We study a periodic medium driven over a random or periodic substrate. Our work is based on nonequilibrium continuum hydrodynamic equations of motion, which we derive microscopical…
Chiral Metal as a Ferromagnetic Super Spin Chain
Leon Balents, Matthew P. A. Fisher, Martin R. Zirnbauer
The electrons on the surface of a disordered multi-layer integer quantum Hall system constitute an unusual chiral metal with ballistic motion transverse to the field, and diffusive…
Critical Behavior of the Supersolid transition in Bose-Hubbard Models
Erwin Frey, Leon Balents
We study the phase transitions of interacting bosons at zero temperature between superfluid (SF) and supersolid (SS) states. The latter are characterized by simultaneous off-diagon…
Comment on "Moving Glass Phase of Driven Lattices"
Leon Balents, M. Cristina Marchetti, Leo Radzihovsky
We consider a periodic lattice rapidly driven through a quenched random potential as a model of a moving Abrikosov lattice. In addition to the transverse phonon displacements …
Dynamical Transition in Sliding Charge-density Waves with Quenched Disorder
Lee-Wen Chen, Leon Balents, Matthew P. A. Fisher +1
We have studied numerically the dynamics of sliding charge-density waves (CDWs) in the presence of impurities in d=1,2. The model considered exhibits a first order dynamical transi…
