The destruction of Fermi liquid behavior when a gapless Fermi surface is coupled to a fluctuating gapless boson field is studied theoretically. This problem arises in a number of different contexts in quantum many body physics. Examples include fermions coupled to a fluctuating transverse gauge field pertinent to quantum spin liquid Mott insulators, and quantum critical metals near a Pomeranchuk transition. We develop a new controlled theoretical approach to determining the low energy physics… 
Non-fermi liquid fixed point in a Wilsonian theory of quantum critical metals
Recently there has been significant interest in new types of metals called non-Fermi liquids, which cannot be described by Landau Fermi liquid theory. Landau Fermi liquid theory is a theoretical
Two-Dimensional Non-Fermi-Liquid Metals: A Solvable Large-N Limit.
TLDR
It is shown that an alternate approach, in which the fermions belong to the fundamental representation of a global SU(N) flavor symmetry, while the order parameter fields transform under the adjoint representation (a "matrix large-N" theory), yields a tractable large N limit.
Lattice models for non-Fermi liquids with tunable transport scalings
A variety of exotic non-fermi liquid (NFL) states have been observed in many condensed matter systems, with different scaling relations between transport coefficients and temperature. The "standard"
Quantum critical properties of a metallic spin density wave transition
We report on numerically exact determinantal quantum Monte Carlo simulations of the onset of spin-density wave (SDW) order in itinerant electron systems captured by a sign-problem-free
Gifts from anomalies: Exact results for Landau phase transitions in metals
Non-Fermi liquid phenomena arise naturally near critical points of Landau ordering transitions in metallic systems, where strong fluctuations of a bosonic order parameter destroy coherent
Quantum chaos on a critical Fermi surface
TLDR
The results establish a connection between quantum dephasing and energy transport in states of quantum matter without quasiparticles, and characterize the quantum chaos in a model of fermions at nonzero density coupled to an emergent gauge field.
Lectures on holographic non-Fermi liquids and quantum phase transitions
In these lecture notes we review some recent attempts at searching for non-Fermi liquids and novel quantum phase transitions in holographic systems using gauge/gravity duality. We do this by studying
Nonperturbative emergence of non-Fermi-liquid behavior in d=2 quantum critical metals
Landau theory of Fermi liquids is the foundational concept behind our understanding of conventional metals. Its basic postulate is that the low-energy physics can be described by weakly interacting
Instabilities of quantum critical metals in the limit N f → 0
We study a model in 2+1 dimensions composed of a Fermi surface of N f flavors of fermions coupled to scalar fluctuations near quantum critical points (QCPs). The N f → 0 limit allows us to
