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…
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…
