Cím: A NEW FAMILY OF SU(2) SYMMETRICAL INTEGRABLE σ-MODELS
Szerző: ; ; ;

(1994)
Local Lagrangians are derived for a class of SU(2) invariant sigma models admitting two commuting Kac-Moody algebras at the level of Poisson brackets. The one-loop renormalizability of these models is established. Some ...
Cím: Mass loss and longevity of gravitationally bound oscillating scalar lumps (oscillatons) in D dimensions
Szerző: ; ;
Dátum: 2010

(2010)
Spherically symmetric oscillatons (also referred to as oscillating soliton stars) i.e. gravitationally bound oscillating scalar lumps are considered in theories containing a massive self-interacting real scalar field coupled ...

Dátum: 1996

(1996)
A modification of the Abelian duality transformations is proposed guaranteeing that a (not necessarily conformally invariant) sigma-model be quantum equivalent (at least up to two loops in perturbation theory) to its dual. ...
Cím: Quantum equivalence of sigma models related by non-Abelian duality transformations

Coupling constant renormalization is investigated in two dimensional σ models related by non-Abelian duality transformations. In this respect it is shown that in the one loop order of perturbation theory the duals of a one ...

The problem of quantum equivalence between non-linear sigma models related by Abelian or non-Abelian T-duality is studied in perturbation theory. Using the anomalous Ward identity for Weyl symmetry we derive a relation ...
