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…
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…
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…
Critical Dynamics of Superconductors in the Charged Regime
Courtney Lannert, Smitha Vishveshwara, Matthew P. A. Fisher
We investigate the finite temperature critical dynamics of three-dimensional superconductors in the charged regime, described by a transverse gauge field coupling to the supercondu…
Pyrochlore Photons: The U(1) Spin Liquid in a S=1/2 Three-Dimensional Frustrated Magnet
Michael Hermele, Matthew P. A. Fisher, Leon Balents
We study the S=1/2 Heisenberg antiferromagnet on the pyrochlore lattice in the limit of strong easy-axis exchange anisotropy. We find, using only standard techniques of degenerate…
