Mirror symmetry and line operators
Tudor Dimofte, Niklas Garner, Michael Geracie +1
We study half-BPS line operators in 3d N=4 gauge theories, focusing in particular on the algebras of local operators at their junctions. It is known that there are two basic types…
Schwinger-Keldysh superspace in quantum mechanics
Michael Geracie, Felix M. Haehl, R. Loganayagam +3
We examine, in a quantum mechanical setting, the Hilbert space representation of the BRST symmetry associated with Schwinger-Keldysh path integrals. This structure had been postula…
Transport in Superfluid Mixtures
Michael Geracie
We present a general method for constructing effective field theories for non-relativistic superfluids, generalizing the previous approaches of Greiter, Witten, and Wilczek, and So…
Galilean Geometry in Condensed Matter Systems
Michael Geracie
We present a systematic means to impose Galilean invariance within field theory. We begin by defining the most general background geometries consistent with Galilean invariance and…
Physical stress, mass, and energy for non-relativistic matter
Michael Geracie, Kartik Prabhu, Matthew M. Roberts
For theories of relativistic matter fields there exist two possible definitions of the stress-energy tensor, one defined by a variation of the action with the coframes at fixed con…
Covariant effective action for a Galilean invariant quantum Hall system
Michael Geracie, Kartik Prabhu, Matthew M. Roberts
We construct effective field theories for gapped quantum Hall systems coupled to background geometries with local Galilean invariance i.e. Bargmann spacetimes. Along with an electr…
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…
Curved non-relativistic spacetimes, Newtonian gravitation and massive matter
Michael Geracie, Kartik Prabhu, Matthew M. Roberts
There is significant recent work on coupling matter to Newton-Cartan spacetimes with the aim of investigating certain condensed matter phenomena. To this end, one needs to have a c…
Fields and fluids on curved non-relativistic spacetimes
Michael Geracie, Kartik Prabhu, Matthew M. Roberts
We consider non-relativistic curved geometries and argue that the background structure should be generalized from that considered in previous works. In this approach the derivative…
Hall viscosity, spin density, and torsion
Michael Geracie, Siavash Golkar, Matthew M. Roberts
We investigate the relationship between Hall viscosity, spin density and response to geometric torsion. For the most general effective action for relativistic gapped systems, the p…
Hydrodynamics on the lowest Landau level
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…
Thermal Transport in a Noncommutative Hydrodynamics
Michael Geracie, Dam Thanh Son
We find the hydrodynamic equations of a system of particles constrained to be in the lowest Landau level. We interpret the hydrodynamic theory as a Hamiltonian system with the Pois…
Spacetime Symmetries of the Quantum Hall Effect
Michael Geracie, Dam Thanh Son, Chaolun Wu +1
We study the symmetries of non-relativistic systems with an emphasis on applications to the fractional quantum Hall effect. A source for the energy current of a Galilean system is…
Effective field theory for fluids: Hall viscosity from a Wess-Zumino-Witten term
Michael Geracie, Dam Thanh Son
We propose an effective action that describe a relativistic fluid with Hall viscosity. The construction involves a Wess-Zumino-Witten term that exists only in (2+1) spacetime dimen…
Conventional and charge six superfluids from melting hexagonal Fulde-Ferrell-Larkin-Ovchinnikov phases in two dimensions
D. F. Agterberg, M Geracie, H. Tsunetsugu
We consider defect mediated melting of Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) and pair density wave (PDW) phases in two dimensions. Examining mean-field ground states in which the…
