Effective field theory and classical equations of motion
Harvey S. Reall, Claude M. Warnick
Given a theory containing both heavy and light fields (the UV theory), a standard procedure is to integrate out the heavy field to obtain an effective field theory (EFT) for the li…
Local metrics admitting a principal Killing-Yano tensor with torsion
Tsuyoshi Houri, David Kubiznak, Claude M. Warnick +1
In this paper we initiate a classification of local metrics admitting the principal Killing--Yano tensor with a skew-symmetric torsion. It is demonstrated that in such spacetimes r…
Hidden symmetry in the presence of fluxes
David Kubiznak, Claude M. Warnick, Pavel Krtous
We derive the most general first order symmetry operator for the Dirac equation coupled to arbitrary fluxes. Such an operator is given in terms of an inhomogenous form omega which…
Non-existence of Skyrmion-Skyrmion and Skyrmion-anti-Skyrmion static equilibria
G. W. Gibbons, C. M. Warnick, W. W. Wong
We consider classical static Skyrmion-anti-Skyrmion and Skyrmion-Skyrmion configurations, symmetric with respect to a reflection plane, or symmetric up to a -parity transformati…
Generalized hidden symmetries and the Kerr-Sen black hole
Tsuyoshi Houri, David Kubiznak, Claude M. Warnick +1
We elaborate on basic properties of generalized Killing-Yano tensors which naturally extend Killing-Yano symmetry in the presence of skew-symmetric torsion. In particular, we discu…
Symmetries of the Dirac operator with skew-symmetric torsion
Tsuyoshi Houri, David Kubiznak, Claude Warnick +1
In this paper, we consider the symmetries of the Dirac operator derived from a connection with skew-symmetric torsion. We find that the generalized conformal Killing-Yano tensors g…
