Snowmass White Paper: Effective Field Theories for Condensed Matter Systems
Tomas Brauner, Sean A. Hartnoll, Pavel Kovtun +6
We review recent progress and a number of future directions for applications of effective field theory methods to condensed matter systems broadly defined. Our emphasis is on areas…
Nonrelativistic effective field theories with enhanced symmetries and soft behavior
Martin A. Mojahed, Tomáš Brauner
We systematically explore the landscape of nonrelativistic effective field theories with a local -matrix and enhanced symmetries and soft behavior. The exploration is carried ou…
Field theories with higher-group symmetry from composite currents
Tomas Brauner
Higher-form symmetries are associated with transformations that only act on extended objects, not on point particles. Typically, higher-form symmetries live alongside ordinary, poi…
Remarks on relativistic scalar models with chemical potential
Tomas Brauner
We discuss selected aspects of classical relativistic scalar field theories with nonzero chemical potential. First, we offer a review of classical field theory at nonzero density w…
Exceptional nonrelativistic effective field theories with enhanced symmetries
Tomas Brauner
We initiate the classification of nonrelativistic effective field theories (EFTs) for Nambu-Goldstone (NG) bosons, possessing a set of redundant, coordinate-dependent symmetries. S…
Noether currents of locally equivalent symmetries
Tomas Brauner
Local symmetry transformations play an important role for establishing the existence and form of a conserved (Noether) current in systems with a global continuous symmetry. We expl…
