Chiral Gravitons on the Lattice
Hernan B. Xavier, Zeno Bacciconi, Titas Chanda +2
Chiral graviton modes are elusive excitations arising from the hidden quantum geometry of fractional quantum Hall states. It remains unclear, however, whether this picture extends…
Nonlinear Lifshitz Photon Theory in Condensed Matter Systems
Yi-Hsien Du, Cenke Xu, Dam Thanh Son
We present an interacting theory of a gauge boson with a quadratic dispersion relation, which we call the "nonlinear Lifshitz photon theory.'' The Lifshitz photon is a three…
Nonlinear Bosonization of Fermi Surfaces: The Method of Coadjoint Orbits
Luca V. Delacretaz, Yi-Hsien Du, Umang Mehta +1
We develop a new method for bosonizing the Fermi surface based on the formalism of the coadjoint orbits. This allows one to parametrize the Fermi surface by a bosonic field that de…
Noncommutative gauge symmetry in the fractional quantum Hall effect
Yi-Hsien Du, Umang Mehta, Dam Thanh Son
We show that a system of particles on the lowest Landau level can be coupled to a probe U(1) gauge field in such a way that the theory is invariant under a noncommut…
Duality between Quantum Critical Points
T. Senthil, Dam Thanh Son, Chong Wang +1
Duality refers to two equivalent descriptions of the same theory from different points of view. Recently there has been tremendous progress in formulating and understanding possibl…
Berry Fermi Liquid Theory
Jing-Yuan Chen, Dam Thanh Son
We develop an extension of the Landau Fermi liquid theory to systems of interacting fermions with non-trivial Berry curvature. We propose a kinetic equation and a constitutive rela…
