Nonrelativistic Conformal Field Theories in the Large Charge Sector
S. M. Kravec, Sridip Pal
We study Schrödinger invariant field theories (nonrelativistic conformal field theories) in the large charge (particle number) sector. We do so by constructing the effective field…
Reparameterization Invariant Operator Basis for NRQED and HQET
Andrew Kobach, Sridip Pal
We discuss how reparameterization invariance connects a rotationally-invariant heavy particle effective theory with a single fermion to a Lorentz-invariant theory. Using Hilbert-se…
Conformal Structure of the Heavy Particle EFT Operator Basis
Andrew Kobach, Sridip Pal
An operator basis of an effective theory with a heavy particle, subject to external gauge fields, is spanned by a particular kind of neutral scalar primary of the nonrelativistic c…
Existence and Construction of Galilean invariant Theories
Benjamin Grinstein, Sridip Pal
We prove a no-go theorem for the construction of a Galilean boost invariant and anisotropic scale invariant field theory with a finite dimensional basis of fields. Two poi…
Unitarity and Universality in non relativistic Conformal Field theory
Sridip Pal
We relate the notion of unitarity of a invariant field theory with that of a Schrodinger field theory using the fact that is a subgroup of Sch…
