Quantal Overlapping Resonance Criterion in the Pullen Edmonds Model
S. Graffi, V. R. Manfredi, L. Salasnich
In order to highlight the onset of chaos in the Pullen-Edmonds model a quantal analog of the resonance overlap criterion has been examined. A quite good agreement between analytica…
The generalized chiral Schwinger model on the two-sphere
A. Bassetto, L. Griguolo
A family of theories which interpolate between vector and chiral Schwinger models is studied on the two--sphere . The conflict between the loss of gauge invariance and globa…
k-Anomalies and Space-Time Supersymmetry in the Green-Schwarz Heterotic Superstring
A. Candiello, K. Lechner, M. Tonin
The computation of -anomalies in the Green-Schwarz heterotic superstring sigma-model and the corresponding Wess-Zumino consistency condition constitute a powerful alternative ap…
Supersymmetry and SU(2)xU(1) breaking with naturally vanishing vacuum energy
A. Brignole, F. Zwirner
We show how the spontaneous breaking of local N=1 supersymmetry and of the SU(2)xU(1) gauge symmetry can be simultaneously realized, with naturally vanishing tree-level vacuum ener…
A Class of Quantum States with Classical-like Evolution
S. De Martino, S. De Siena, F. Illuminati
In the framework of Nelson stochastic quantization we derive exact non-stationary states for a class of time-dependent potentials. The wave-packets follow a classical motion with c…
Nonperturbative 2D Gravity, Punctured Spheres and -Vacua in String Theories
G. Bonelli, P. A. Marchetti, M. Matone
We consider a model of 2D gravity with the coefficient of the Einstein-Hilbert action having an imaginary part . This is equivalent to introduce a -vacuum structure in the…
Classical and quantum dissipation in non homogeneous environments
F. Illuminati, M. Patriarca, P. Sodano
We generalize the oscillator model of a particle interacting with a thermal reservoir by introducing arbitrary nonlinear couplings in the particle coordinates.The equilibrium posit…
Anomalous dimensions and ghost decoupling in a perturbative approach to the generalized chiral Schwinger model
A. Bassetto, L. Griguolo
A generalized chiral Schwinger model is studied by means of perturbative techniques. Explicit expressions are obtained, both for bosonic and fermionic propagators, and compared to…
The supersymmetric version of the Green--Schwarz anomaly cancellation mechanism
A. Candiello, K. Lechner
The , Supergravity--Super--Yang--Mills (SUGRA-SYM) theory is plagued by ABBJ gauge and Lorentz anomalies which are cancelled via the Green-Schwarz anomaly cancellation…
Nonperturbative Model Of Liouville Gravity
M. Matone
We obtain nonperturbative results in the framework of continuous Liouville theory. In particular, we express the specific heat of pure gravity in terms of an expansion o…
Light--like Wilson loops and gauge invariance of Yang--Mills theory in 1+1 dimensions
A. Bassetto, F. De Biasio, L. Griguolo
A light-like Wilson loop is computed in perturbation theory up to for pure Yang--Mills theory in 1+1 dimensions, using Feynman and light--cone gauges to check its…
WBase: a C package to reduce tensor products of Lie algebra representations
A. Candiello
It is nearly twenty years that there exist computer programs to reduce products of Lie algebra irreps. This is a contribution in the field that uses a modern computer language (``C…
