Superselection rule for the cosmological constant in three-dimensional spacetime
Claudio Bunster, Alfredo Perez
Efforts to understand the origin of the cosmological constant Λ and its observed value have led to consider it as a dynamical field rather than as a universal constant. Then the po…
Higher spin extension of cosmological spacetimes in 3D: asymptotically flat behaviour with chemical potentials and thermodynamics
Javier Matulich, Alfredo Perez, David Tempo +1
A generalized set of asymptotic conditions for higher spin gravity without cosmological constant in three spacetime dimensions is constructed. They include the most general tempora…
Asymptotic symmetries of three-dimensional higher-spin gravity: the metric approach
Andrea Campoleoni, Marc Henneaux
The asymptotic structure of three-dimensional higher-spin anti-de Sitter gravity is analyzed in the metric approach, in which the fields are described by completely symmetric tenso…
Stationary axisymmetric spacetimes with a conformally coupled scalar field
Marco Astorino
Solution generating techniques for general relativity with a conformally (and minimally) coupled scalar field are pushed forward to build a wide class of asymptotically flat, axisy…
Soliton defects in one-gap periodic system and exotic supersymmetry
Adrian Arancibia, Francisco Correa, Vit Jakubsky +2
By applying Darboux-Crum transformations to the quantum one-gap Lame system, we introduce an arbitrary countable number of bound states into forbidden bands. The perturbed potentia…
Confining Strings in Supersymmetric Theories with Higgs Branches
Mikhail Shifman, Gianni Tallarita, Alexei Yung
We study flux tubes (strings) on the Higgs branches in supersymmetric gauge theories. In generic vacua on the Higgs branches strings were shown to develop long-range "tails" associ…
