Detectors in Nonrelativistic Conformal Field Theories
Cyuan-Han Chang, Subham Dutta Chowdhury, Ian Moult +1
Correlations in asymptotic fluxes provide one of the primary experimental means of studying physical systems. In the context of relativistic QFT, the formalization of such experime…
Nonrelativistic Conformal Collider Physics of Multiparticle Point Production
Cyuan-Han Chang, Subham Dutta Chowdhury, Ian Moult +1
We define detector operators in the nonrelativistic conformal field theory describing fermions at unitarity. We reduce the problem of computing the momentum distribution and correl…
Theory of Spinful Relativistic Superfluids
Dam Thanh Son
We construct an effective field theory description of relativistic superfluids with nonzero angular momentum density. At first order in the derivative expansion, the effective acti…
Short-distance production of three particles with large scattering length
Timothy G. Backert, Sebastian Dietz, Hans-Werner Hammer +2
The short-distance production of multi-particle states in high-energy nuclear reactions provides a unique way to study the low-energy properties of few-body systems. In particular,…
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…
Relativistic Guiding-Center Motion: Action Principle, Kinetic Theory, and Hydrodynamics
Dam Thanh Son, Mikhail Stephanov
We treat the guiding-center dynamics in a varying external Maxwell field using a relativistically covariant action principle which reproduces the known Vandervoort expression for t…
Applied nonrelativistic conformal field theory: scattering-length and effective-range corrections to unnuclear physics
Subham Dutta Chowdhury, Ruchira Mishra, Dam Thanh Son
Due to an accidentally large -wave scattering length, in a relatively wide range of energy, neutrons are approximately described by the nonrelativistic conformal field theory of…
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…
Fate of Multiparticle Resonances: From -Balls to He Droplets
Dam Thanh Son, Mikhail Stephanov, Ho-Ung Yee
We consider a system of nonrelativistic particles which form a near-threshold resonance. Assuming no subset of these particles can form a bound state, the resonance can only 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…
Unnuclear physics
Hans-Werner Hammer, Dam Thanh Son
We investigate a nonrelativistic version of Georgi's "unparticle physics." We define the unnucleus as a field in a nonrelativistic conformal field theory. Such a field is character…
Rotons in Anyon Superfluids
Yi-Hsien Du, Umang Mehta, Dam Thanh Son
We consider the problem of calculating the excitation spectrum of a gas of nonrelativistic anyons. When the anyons have statistics close to fermionic and the statistical angle has…
Bosonic superfluid on lowest Landau level
Sergej Moroz, Dam Thanh Son
We develop a low-energy effective field theory of a two-dimensional bosonic superfluid on the lowest Landau level at zero temperature and identify a Berry term that governs the dyn…
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…
Duality and Universal Transport in a Mixed-Dimension Electrodynamics
Wei-Han Hsiao, Dam Thanh Son
We consider a theory of a two-component Dirac fermion localized on a (2+1) dimensional brane coupled to a (3+1) dimensional bulk. Using the fermionic particle-vortex duality, we sh…
Particle-hole symmetry and electromagnetic response of a half-filled Landau level
Michael Levin, Dam Thanh Son
We derive exact physical consequences of particle-hole symmetry of the state of electrons in a strong magnetic field. We show that if the symmetry is not spontaneously brok…
The Dirac composite fermion of the fractional quantum Hall effect
Dam Thanh Son
We review the recently proposed Dirac composite fermion theory of the half-filled Landau level. This paper is based on a talk given at the Nambu Symposium at University of Chicago,…
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…
Dense Chern-Simons Matter with Fermions at Large N
Michael Geracie, Mikhail Goykhman, Dam T. Son
In this paper we investigate properties of Chern-Simons theory coupled to massive fermions in the large N limit. We demonstrate that at low temperatures the system is in a Fermi li…
Is the Composite Fermion a Dirac Particle?
Dam Thanh Son
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 fie…
Fractional charge and inter-Landau level states at points of singular curvature
Rudro R. Biswas, Dam T. Son
The quest for universal signatures of topological phases is fundamentally important since these properties are robust to variations in system-specific details. Here we present gene…
Operator Product Expansion and Conservation Laws in Non-Relativistic Conformal Field Theories
Siavash Golkar, Dam T. Son
We explore the consequences of conformal symmetry for the operator product expansions in nonrelativistic field theories. Similar to the relativistic case, the OPE coefficients of d…

Michael Geracie, Dam Thanh Son
Using the recently developed approach to quantum Hall physics based on Newton-Cartan geometry, we consider the hydrodynamics of an interacting system on the lowest Landau level. We…
