Non-compact nonlinear sigma models

Physics Letters B, 2016
The target space of a nonlinear sigma model is usually required to be positive definite to avoid ghosts. We introduce a unique class of nonlinear sigma models where the target space metric has a Lorentzian signature, thus the associated group being non ...

DUALITY IN FUZZY SIGMA MODELS [PDF]

International Journal of Modern Physics A, 2004
Nonlinear "sigma" models in two dimensions have BPS solitons which are solutions of self- and anti-self-duality constraints. In this paper, we find their analogues for fuzzy sigma models on fuzzy spheres which were treated in detail by us in earlier work.

Renormalization of supersymmetric Lifshitz sigma models

Journal of High Energy Physics, 2023
We study the renormalization of an N $$ \mathcal{N} $$ = 1 supersymmetric Lifshitz sigma model in three dimensions. The sigma model exhibits worldvolume anisotropy in space and time around the high-energy z = 2 Lifshitz point, such that the worldvolume ...

The transcriptional response of Drosophila melanogaster to infection with the sigma virus (Rhabdoviridae). [PDF]

, 2009
Bacterial and fungal infections induce a potent immune response in Drosophila melanogaster, but it is unclear whether viral infections induce an antiviral immune response.

Non-local non-linear sigma models

Journal of High Energy Physics, 2019
We study non-local non-linear sigma models in arbitrary dimension, focusing on the scale invariant limit in which the scalar fields naturally have scaling dimension zero, so that the free propagator is logarithmic.

Models for Quadratic Algebras Associated with Second Order Superintegrable Systems in 2D [PDF]

, 2008
There are 13 equivalence classes of 2D second order quantum and classical superintegrable systems with nontrivial potential, each associated with a quadratic algebra of hidden symmetries.

The age and evolution of an antiviral resistance mutation in Drosophila melanogaster [PDF]

, 2007
What selective processes underlie the evolution of parasites and their hosts? Arms-race models propose that new host-resistance mutations or parasite counter-adaptations arise and sweep to fixation.
