Supersymmetric Poisson and Poisson-supersymmetric sigma models
Thomas Basile, Athanasios Chatzistavrakidis, Sylvain Lavau
We revisit and construct new examples of supersymmetric 2D topological sigma models whose target space is a Poisson supermanifold. Inspired by the AKSZ construction of topological…
Star-products for Lie-algebraic noncommutative Minkowski space-times
Valentine Maris, Filip Požar, Jean-Christophe Wallet
Poisson structures of the Poincaré group can be linked to deformations of the Minkowski space-time, classified some time ago by Zakrewski. Based on this classification, various qua…
Homotopy Manin Theories: Generalising Third-Way, Yang-Mills and Integrable Sigma Models
Alex S. Arvanitakis, Leron Borsten, Dimitri Kanakaris +1
Manin theories are a class of non-topological deformations of Chern-Simons theories that naturally realise the third-way mechanism and furthermore admit localisation despite not be…
Towards new relativistic doubly -deformed D=4 quantum phase spaces
Jerzy Lukierski, Stjepan Meljanac, Salvatore Mignemi +2
We propose new noncommutative models of quantum phase spaces, containing a pair of -deformed Poincaré algebras, with two independent double ()-deformations in space-t…
Entropy of black holes, charged probes and noncommutative generalization
Axel Hrelja, Tajron Jurić, Filip Požar
The brick wall model is a semi-classical approach to understanding the microscopic origin of black hole entropy. We outline the formalism for the brick wall model in arbitrary numb…
Semiclassical solution of black hole information paradox
Hrvoje Nikolic
We resolve black hole information paradox within semiclassical gravity, in a manner that does not depend on details of unknown quantum gravity. Our crucial insight is that outgoing…
