Supersymmetric domain walls in maximal 6D gauged supergravity I
European Physical Journal C: Particles and Fields, 2021 We find a large class of supersymmetric domain wall solutions from six-dimensional $$N=(2,2)$$ N = ( 2 , 2 ) gauged supergravity with various gauge groups.

Measures of non-Gaussianity in axion-string-induced CMB birefringence [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 The presence of axion strings in the Universe after recombination can leave an imprint on the polarization pattern of the cosmic microwave background radiation through the phenomenon of axion-string-induced birefringence via the hyperlight axion-like ...

Journal of High Energy Physics, 2020 The double copy formalism provides an intriguing connection between gauge theories and gravity. It was first demonstrated in the perturbative context of scattering amplitudes but recently the formalism has been applied to exact classical solutions in ...

Asymptotically Nonrelativistic String Backgrounds [PDF]
International Journal of Modern Physics A, 2023 In recent years, interesting curved-space extensions of nonrelativistic (NR) string theory have been very actively pursued, where the background has a structure that is a stringy generalization of Newton-Cartan geometry.

Topological strings and their physical applications [PDF]
Surveys in Differential Geometry, 2005 We give an introductory review of topological strings and their application to various aspects of superstrings and supersymmetric gauge theories. This review includes developing the necessary mathematical background for topological strings, such as the notions of Calabi-Yau manifold and toric geometry, as well as physical methods developed for solving ...

Horizon-scale tests of gravity theories and fundamental physics from the Event Horizon Telescope image of Sagittarius A ∗ [PDF]
Classical and quantum gravity, 2022 Horizon-scale images of black holes (BHs) and their shadows have opened an unprecedented window onto tests of gravity and fundamental physics in the strong-field regime.

Monopoles, shockwaves and the classical double copy
Journal of High Energy Physics, 2020 The classical double copy relates exact solutions in biadjoint scalar, gauge and gravity theories. Recently, nonperturbative solutions have been found in biadjoint theory, which have been speculated to be related to the Wu-Yang monopole in gauge theory ...

Superradiance in string theory [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance excludes some regions of Calabi-Yau moduli space. Regardless of the cosmological

On the black hole/string transition [PDF]
Journal of High Energy Physics, 2021 We discuss aspects of the possible transition between small black holes and highly excited fundamental strings. We focus on the connection between black holes and the self gravitating string solution of Horowitz and Polchinski.
