Stringy bounces and gradient instabilities
Massimo Giovannini
Bouncing solutions are obtained from a generally covariant action characterized by a potential which is a nonlocal functional of the dilaton field at two separated space-time point…
Spectral boundary conditions and solitonic solutions in a classical Sellmeier dielectric
F. Belgiorno, S. L. Cacciatori, A. Viganò
Electromagnetic field interactions in a dielectric medium represent a longstanding field of investigation, both at the classical level and at the quantum one. We propose a 1+1 dime…
Black string first order flow in N=2, d=5 abelian gauged supergravity
Dietmar Klemm, Nicolò Petri, Marco Rabbiosi
We derive both BPS and non-BPS first-order flow equations for magnetically charged black strings in five-dimensional N=2 abelian gauged supergravity, using the Hamilton-Jacobi form…
Higgs Potential from Derivative Interactions
A. Quadri
A formulation of the linear model with derivative interactions is studied. The classical theory is on-shell equivalent to the model with the standard quartic Higgs potentia…
Supersymmetric solutions of SU(2)-Fayet-Iliopoulos-gauged N=2,d=4 supergravity
Tomas Ortin, Camilla Santoli
We explore the construction of supersymmetric solutions of theories of N=2,d=4 supergravity with a SU(2) gauging and SU(2) Fayet-Iliopoulos terms. In these theories an SU(2) isomet…
One-Dimensional Super Calabi-Yau Manifolds and their Mirrors
Simone Noja, Sergio Luigi Cacciatori, Francesco Dalla Piazza +2
We apply a definition of generalised super Calabi-Yau variety (SCY) to supermanifolds of complex dimension one. One of our results is that there are two SCY's having reduced manifo…
Modified Lorentz transformations in deformed special relativity
G. Salesi, M. Greselin, L. Deleidi +1
We extend a recent approach to Deformed Special Relativity based on deformed dispersion laws, entailing modified Lorentz transformations and, at the same time, noncommutative geome…
Non-Abelian black string solutions of N=(2,0),d=6 supergravity
Pablo A. Cano, Tomas Ortin, Camilla Santoli
We show that, when compactified on a circle, N=(2,0),d=6 supergravity coupled to 1 tensor multiplet and nV vector multiplets is dual to N=(2,0),d=6 supergravity coupled to just nT=…
Duality invariance in Fayet-Iliopoulos gauged supergravity
Sergio L. Cacciatori, Dietmar Klemm, Marco Rabbiosi
We propose a geometric method to study the residual symmetries in , Fayet-Iliopoulos (FI) gauged supergravity. It essentially involves the stabilization of…
Symplectically invariant flow equations for N=2, D=4 gauged supergravity with hypermultiplets
Dietmar Klemm, Nicolò Petri, Marco Rabbiosi
We consider N=2 supergravity in four dimensions, coupled to an arbitrary number of vector- and hypermultiplets, where abelian isometries of the quaternionic hyperscalar target mani…
Path integral quantization of the relativistic Hopfield model
F. Belgiorno, S. L. Cacciatori, F. Dalla Piazza +1
The path integral quantization method is applied to a relativistically covariant version of the Hopfield model, which represents a very interesting mesoscopic framework for the des…
