Tunable transport with broken space–time symmetries [PDF]
Physics Reports, 2014 Transport properties of particles and waves in spatially periodic structures that are driven by external time-dependent forces manifestly depend on the space-time symmetries of the corresponding equations of motion. A systematic analysis of these symmetries uncovers the conditions necessary for obtaining directed transport.

Phonon-induced Floquet topological phases protected by space-time symmetries [PDF]
Physical Review Research, 2020 For systems with spatial and nonspatial symmetries, the topological classification depends not only on these symmetries but also on the commutation/anticommutation relations between spatial and nonspatial symmetries.

Space-time symmetries in gauge theories [PDF]
Communications in Mathematical Physics, 1980 A general definition of symmetries of gauge fields is proposed and a method developed for constructing symmetric fields for an arbitrary gauge group. Scalar fields occur naturally in the formalism and the pure gauge theory reduces to a Higgs model in lower dimensions.

The fermionic signature operator and space-time symmetries [PDF]
Advances in Theoretical and Mathematical Physics, 2018 We show that and specify how space-time symmetries give rise to corresponding symmetries of the fermionic signature operator and generalized fermionic projector states.

Broken space-time symmetries and mechanisms of rectification of ac fields by nonlinear (non)adiabatic response [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2002 We consider low-dimensional dynamical systems exposed to a heat bath and to additional ac fields. The presence of these ac fields may lead to a breaking of certain spatial or temporal symmetries, which in turn cause nonzero averages of relevant ...

ON THE SPACE–TIME SYMMETRIES OF NONCOMMUTATIVE GAUGE THEORIES [PDF]
, 2002 We study the space–time symmetries and transformation properties of the non-commutative U(1) gauge theory, by using Noether charges. We carry out our analysis by keeping an open view on the possible ways θμν could transform.

Symplectic geometry and Noether charges for Hopf algebra space-time symmetries [PDF]
, 2007 There has been a certain interest in some recent works in the derivation of Noether charges for Hopf algebra space-time symmetries. Such analyses relied rather heavily on delicate manipulations of the fields of noncommuting coordinates whose charges were

GHOST COHOMOLOGIES AND HIDDEN SPACE–TIME SYMMETRIES [PDF]
International Journal of Modern Physics A, 2007 We observe and study new nonlinear global space–time symmetries of the full ghost + matter action of RNS superstring theory. We show that these surprising new symmetries are generated by the special worldsheet currents (physical vertex operators) of RNS superstring theory, violating the equivalence of superconformal ghost pictures.
