Comment on "Axion-matter coupling in multiferroics"
Alexander Balatsky, Benjo Fraser
A previous publication [H. S. Roising et al., Phys. Rev. Research 3, 033236 (2021)] involving the current authors pointed out a coupling between dark matter axions and ferroic orde…
Dark Sound
Alexander Balatsky, Benjo Fraser, Henrik Roising
We discuss the axion dark matter (DM) condensate and the consequences the interactions of dark matter would have on the spectrum of collective modes. We find that DM self-interacti…
Axion-matter coupling in multiferroics
Henrik S. Røising, Benjo Fraser, Sinéad M. Griffin +4
Multiferroics (MFs) are materials with two or more ferroic orders, like spontaneous ferroelectric and ferromagnetic polarizations. Such materials can exhibit a magnetoelectric effe…
D-branes (or not) in the non-Abelian T-dual of the SU(2) WZW model
Benjo Fraser
Following on from arXiv:1805.03657, we consider open strings in the non-Abelian T-dual of the WZW model, with respect to the vector isometry. Since in this case t…
Non-Abelian T-duality and Modular Invariance
Benjo Fraser, Dimitrios Manolopoulos, Konstantinos Sfetsos
Two-dimensional -models corresponding to coset CFTs of the type admit a zoom-in limit invol…
Higher rank Wilson loops in the conformal quiver
Benjo Fraser
In this note we compute the expectation value of a circular BPS Wilson loop in the higher rank totally symmetric and antisymmetric representations of SU(N) in the quive…
Emergent Lifshitz scaling from N=4 SYM with supersymmetric heavy-quark density
Anton F. Faedo, Benjo Fraser, S. Prem Kumar
We consider supersymmetric configurations in Type IIB supergravity obtained by the beackreaction of fundamental strings ending on a stack of D3-branes and smeared uniformly in the…
Supersymmetric Lifshitz-like backgrounds from N=4 SYM with heavy quark density
Anton F. Faedo, Benjo Fraser, S. Prem Kumar
We examine a class of gravity backgrounds obtained by considering the backreaction of a spatially uniform density of mutually BPS Wilson lines or heavy quarks in N=4 SUSY Yang-Mill…
