Quantum criticality beyond the Landau-Ginzburg-Wilson paradigm
T. Senthil, Leon Balents, Subir Sachdev +2
We present the critical theory of a number of zero temperature phase transitions of quantum antiferromagnets and interacting boson systems in two dimensions. The most important exa…
Broad relaxation spectrum and the field theory of glassy dynamics for pinned elastic systems
Leon Balents, Pierre Le Doussal
We study thermally activated, low temperature equilibrium dynamics of elastic systems pinned by disorder using one loop functional renormalization group (FRG). Through a series of…
Charge accumulation on a Luttinger liquid
Jason Alicea, Leon Balents, Cristina Bena +1
The average charge Q on a quantum wire, modeled as a single-channel Luttinger liquid, connected to metallic leads and coupled to a gate is studied theoretically. We find that the b…
"Deconfined" quantum critical points
T. Senthil, Ashvin Vishwanath, Leon Balents +2
The theory of second order phase transitions is one of the foundations of modern statistical mechanics and condensed matter theory. A central concept is the observable `order param…
Quantum Criticality and Deconfinement in Phase Transitions Between Valence Bond Solids
Ashvin Vishwanath, L. Balents, T. Senthil
We consider spin-half quantum antiferromagnets in two spatial dimensions in the quantum limit, where the spins are in a valence bond solid (VBS) phase. The transitions between two…
The Roton Fermi Liquid
Leon Balents, Matthew P. A. Fisher
We introduce and analyze a novel metallic phase of two-dimensional (2d) electrons, the Roton Fermi Liquid (RFL), which, in contrast to the Landau Fermi liquid, supports both gaples…
