Is the composite fermion a Dirac particle?

DT Son - Physical Review X, 2015‏ - APS
We propose a particle-hole symmetric theory of the Fermi-liquid ground state of a half-filled
Landau level. This theory should be applicable for a Dirac fermion in the magnetic field at …

Adiabatic hydrodynamics: The eightfold way to dissipation

FM Haehl, R Loganayagam, M Rangamani - Journal of High Energy …, 2015‏ - Springer
A bstract Hydrodynamics is the low-energy effective field theory of any interacting quantum
theory, capturing the long-wavelength fluctuations of an equilibrium Gibbs densitymatrix …

Very-high-energy collective states of partons in fractional quantum hall liquids

AC Balram, Z Liu, A Gromov, Z Papić - Physical Review X, 2022‏ - APS
The low-energy physics of fractional quantum Hall (FQH) states—a paradigm of strongly
correlated topological phases of matter—to a large extent is captured by weakly interacting …

Dirac composite fermion theory of general Jain sequences

DX Nguyen, DT Son - Physical Review Research, 2021‏ - APS
We reconsider the composite fermion theory of general Jain sequences with filling factor ν=
N/(4 N±1). We show that Goldman and Fradkin's proposal of a Dirac composite fermion …

Non-relativistic fields from arbitrary contracting backgrounds

E Bergshoeff, J Rosseel, T Zojer - Classical and Quantum Gravity, 2016‏ - iopscience.iop.org
We discuss a non-relativistic contraction of massive and massless field theories minimally
coupled to gravity. Using the non-relativistic limiting procedure introduced in our previous …

Large charge sector of 3d parity-violating CFTs

G Cuomo, LV Delacretaz, U Mehta - Journal of High Energy Physics, 2021‏ - Springer
A bstract Certain CFTs with a global U (1) symmetry become superfluids when coupled to a
chemical potential. When this happens, a Goldstone effective field theory controls the …

Analog gravity and continuum effective theory of the graphene tight-binding lattice model

MM Roberts, T Wiseman - Physical Review B, 2024‏ - APS
We consider the nearest-neighbor lattice tight-binding model of graphene with slowly
spatially varying hop** functions. We develop a systematic low-energy approximation as a …

Conformal field theories in a magnetic field

R Boyack, L Delacrétaz, É Dupuis… - Physical Review …, 2024‏ - APS
We study the properties of 2+ 1d conformal field theories (CFTs) in a background magnetic
field. Using generalized particle-vortex duality, we argue that in many cases of interest the …

Curved-space Dirac description of elastically deformed monolayer graphene is generally incorrect

MM Roberts, T Wiseman - Physical Review B, 2022‏ - APS
Undistorted monolayer graphene has energy bands which cross at protected Dirac points. It
elastically deforms, and much research has assumed the Dirac description persists, now in a …

Hořava-Lifshitz gravity and effective theory of the fractional quantum Hall effect

C Wu, SF Wu - Journal of High Energy Physics, 2015‏ - Springer
A bstract We show that Hořava-Lifshitz gravity theory can be employed as a covariant
framework to build an effective field theory for the fractional quantum Hall effect that respects …
