Vacuum polarization in two-dimensional static spacetimes and dimensional reduction [PDF]
, 2002 We obtain an analytic approximation for the effective action of a quantum scalar field in a general static two-dimensional spacetime. We apply this to the dilaton gravity model resulting from the spherical reduction of a massive, non-minimally coupled ...

Dimensional Reduction of Cobordism and K-theory
Journal of High Energy Physics, 2023 It has been proposed that cobordism and K-theory groups, which can be mathematically related in certain cases, are physically associated to generalised higher-form symmetries.

Dimensional Reduction for Generalized Poisson Brackets
, 2007 We discuss dimensional reduction for Hamiltonian systems which possess nonconstant Poisson brackets between pairs of coordinates and between pairs of momenta.

From Topology to Generalised Dimensional Reduction [PDF]
, 1996 In the usual procedure for toroidal Kaluza-Klein reduction, all the higher-dimensional fields are taken to be independent of the coordinates on the internal space.

Dimensional Reduction in Non-Supersymmetric Theories
, 1993 It is shown that regularisation by dimensional reduction is a viable alternative to dimensional regularisation in non-supersymmetric theories.Comment: 13 pages, phyzzx, LTH ...

The Dimensional-Reduction Anomaly in Spherically Symmetric Spacetimes [PDF]
, 2000 In D-dimensional spacetimes which can be foliated by n-dimensional homogeneous subspaces, a quantum field can be decomposed in terms of modes on the subspaces, reducing the system to a collection of (D-n)-dimensional fields. This allows one to write bare

Thermal dimensional reduction and black hole evaporation
Physics Letters B, 2021 We analyze how a quantum-gravity-induced change in the number of thermal dimensions (through a modified dispersion relation) affects the geometry and the thermodynamics of a charged black hole.

Universal features of dimensional reduction schemes from general covariance breaking [PDF]
, 2007 Many features of dimensional reduction schemes are determined by the breaking of higher dimensional general covariance associated with the selection of a particular subset of coordinates.

Spin-flux attachment by dimensional reduction of vortices
Nuclear Physics B, 2023 The description of a system of vortices in terms of dual fields provides a window to new phases of the system. It was found recently that dualizing a 3+1-d boson-fermion system leads to a system of fermions and vortices interacting via a 2-form field ...

Generalized Elitzur's Theorem and Dimensional Reduction
, 2005 We extend Elitzur's theorem to systems with symmetries intermediate between global and local. In general, our theorem formalizes the idea of {\it dimensional reduction}.
