Bounded correctors in almost periodic homogenization

We show that certain linear elliptic equations (and systems) in divergence form with almost periodic coefficients have bounded, almost periodic corre…

We describe the most general asymptotically flat, stationary, non-extremal, dyonic black hole of the four-dimensional N = 2 supergravity coupled to 3 vector multiplets that describes the low-energy regime of the STU model. Under U-dualities, this ca…

Seed for general rotating non-extremal black holes of N=8 supergravity

We describe the most general asymptotically flat, stationary, non-extremal, dyonic black hole of the four-dimensional N = 2 supergravity coupled to 3…

This section of the lecture notes is devoted to a certain set of boundary conditions in three-dimensional Einstein gravity that can be interpreted as a black hole carrying soft hair excitations30. We will first review near-horizon boundary condition…

Canonical Charges in Flatland

In this series of lectures we give an introduction to the concept of asymptotic symmetry analysis with a focus on asymptotically flat spacetimes in 2…

Higgs $\to μτ$ in Abelian and Non-Abelian Flavor Symmetry Models

We study lepton flavor violating Higgs decays in two models, with the recently found hint for Higgs $\to \mu \tau$ at CMS as a benchmark value for th…

In this appendix we provide the embedding of the non-minimal N=2 supergravity models analysed in this note into N=8 (maximal) supergravity Cremmer and Julia (1979). In its ungauged version, maximal supergravity possesses an E7(7) global symmetry gro…

Hypermultiplet gaugings and supersymmetric solutions from 11D and m…

Supersymmetric $\,\textrm{AdS}_{4}\,$, $\,\textrm{AdS}_{2} \times \Sigma_{2}\,$ and asymptotically AdS$_{4}$ black hole solutions are studied in the …

D-Brane Probes in the Matrix Model

Recently, a new approach to large N gauge theories, based on a generalization of the concept of D-brane probes to any gauge field theory, was propose…

Large nonlinear Kerr effect in graphene

Under strong laser illumination, few-layer graphene exhibits both a transmittance increase due to saturable absorption and a nonlinear phase shift. H…

Hidden vector dark matter

We show that dark matter could be made of massive gauge bosons whose stability doesn't require to impose by hand any discrete or global symmetry. Sta…

Inert Scalar Doublet Asymmetry as Origin of Dark Matter

In the inert scalar doublet framework, we analyze what would be the effect of a $B-L$ asymmetry that could have been produced in the Universe thermal…

Reconciling leptogenesis with observable mu --> e gamma rates

We perform a detailed analysis of thermal leptogenesis in the framework of seesaw models which approximately conserve lepton number. These models are…

Cold light dark matter in extended seesaw models

We present a thorough discussion of light dark matter produced via freeze-in in two-body decays A -> B DM. If A and B are quasi-degenerate, the dark …
