Space-time symmetries of quantized tensionless strings [PDF]
Physics Letters B, 1992 The tensionless limit of the free bosonic string is space-time conformally symmetric classically. Requiring invariance of the quantum theory in the light cone gauge tests the reparametrization symmetry needed to fix this gauge. The full conformal symmetry gives stronger constraints than the Poincar subalgebra.

Simple space-time symmetries: Generalizing conformal field theory [PDF]
, 2007 We study simple space-time symmetry groups G which act on a space-time manifold M=G∕H which admits a G-invariant global causal structure. We classify pairs (G,M) which share the following additional properties of conformal field theory. (1) The stability

Duality symmetric actions with manifest space-time symmetries. [PDF]
Physical Review D, Particles and fields, 1995 We consider a space-time-invariant duality symmetric action for a free Maxwell field and an SL(2,R)\ifmmode\times\else\texttimes\fi{}SO(6,22)-invariant effective action describing a low-energy bosonic sector of the heterotic string compactified on a six ...

Optical activities as computing resources for space–time symmetries [PDF]
, 2009 It is known that optical activities can perform rotations. It is shown that the rotation, if modulated by attenuations, can perform symmetry operations of Wigner's little group which dictates the internal space–time symmetries of elementary particles.

Apparent fine tunings for field theories with broken space-time symmetries [PDF]
SciPost Physics, 2022 We exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned.

INTERACTING RELATIVISTIC PARTICLE: TIME–SPACE NONCOMMUTATIVITY AND SYMMETRIES [PDF]
, 2007 We discuss the symmetry properties of the reparametrization invariant model of an interacting relativistic particle where the electromagnetic field is taken as the constant background field.

Carroll/fracton particles and their correspondence
Journal of High Energy Physics, 2023 We exploit the close relationship between the Carroll and fracton/dipole algebras, together with the method of coadjoint orbits, to define and classify classical Carroll and fracton particles.

Quantum Carroll/fracton particles
Journal of High Energy Physics, 2023 We classify and relate unitary irreducible representations (UIRs) of the Carroll and dipole groups, i.e., we define elementary quantum Carroll and fracton particles and establish a correspondence between them.
