On the Limit Cycle of an Inflationary Universe

Luca Salasnich

We study the dynamics of a scalar inflaton field with a symmetric double--well potential and prove rigorously the existence of a limit cycle in its phase space. By using analytical…

Testing the equivalence principle through freely falling quantum objects

Lorenza Viola, Roberto Onofrio

Free fall in a uniform gravitational field is revisited in the case of quantum states with and without classical analogue. The interplay between kinematics and dynamics in the evol…

Sum rules for asymptotic form factors in $e^{+} e^{-} - > W^{+} W^{-}$ scattering

F. Feruglio, S. Rigolin

At very large energies and in $S U (2)_{L} \otimes U (1)_{Y}$ gauge theories, the trilinear gauge boson vertices relevant for $e^{+} e^{-} \to W^{+} W^{-}$ scattering are related in a simple way to…

An Improved Measurement of the Left-Right Z0 Cross Section Asymmetry

SLD Collaboration, K. Abe, I. Abt et al

We present a new measurement of the left-right cross section asymmetry (ALR) for Z boson production by e+e- collisions. The measurement was performed at a center-of-mass energy of…

Reentrant Wetting Transition of a Rough Wall

G. Giugliarelli, A. L. Stella

A $2 D$ model describing depinning of an interface from a rough, self-affine substrate, is studied by transfer matrix methods. The phase diagram is determined for several values of…

On Lorentz Invariant Actions for Chiral P-Forms

Paolo Pasti, Dmitri Sorokin, Mario Tonin

We demonstrate how a Lorentz covariant formulation of the chiral p-form model in D=2(p+1) containing infinitely many auxiliary fields is related to a Lorentz covariant formulation…

Quantum nondemolition measurements on two-level atomic systems and temporal Bell inequalities

Tommaso Calarco, Roberto Onofrio

The evolution of a two-level system subjected to stimulated transitions which is undergoing a sequence of measurements of the level occupation probability is evaluated. Its time co…

Collective transition densities in neutron-rich nuclei

F. Catara, E. G. Lanza, M. A. Nagarajan +1

Quadrupole transition densities in neutron-rich nuclei in the vicinity of the neutron drip-line are calculated in the framework of the Random Phase Approximation. The continuum is…

WKB to all orders and the accuracy of the semiclassical quantization

Marko Robnik, Luca Salasnich

We perform a systematic WKB expansion to all orders for a one-dimensional system with potential $V (x) = U_{0} / cos^{2} (α x)$ . We are able to sum the series to the exact energy spectrum.…

World-manifold and target space anomalies in heterotic Green-Schwarz strings and five-branes

Kurt Lechner, Mario Tonin

The quantum consistency of sigma-models describing the dynamics of extended objects in a curved background requires the cancellation of their world-volume anomalies, which are conf…

An Analytical and Numerical Study of Optimal Channel Networks

F. Colaiori, A. Flammini, A. Maritan +1

We analyze the Optimal Channel Network model for river networks using both analytical and numerical approaches. This is a lattice model in which a functional describing the dissipa…

An n=(1|1) super--Toda Model Based on OSp(1|4)

Dmitrij Sorokin, Francesco Toppan

We show that a Hamiltonian reduction of affine Lie superalgebras having bosonic simple roots (such as $O S p (1∣4)$ ) ``does'' produce supersymmetric Toda models, with superconformal s…

Modular Invariance and Structure of the Exact Wilsonian Action of N=2 SYM

Marco Matone

We construct modular invariants on the moduli space of quantum vacua of N=2 SYM with gauge group SU(2). We also introduce a nonchiral function K which is expressed in terms of the…

Solving N=2 SYM by Reflection Symmetry of Quantum Vacua

G. Bonelli, M. Matone, M. Tonin

The recently rigorously proved nonperturbative relation between u and the prepotential, underlying N=2 SYM with gauge group SU(2), implies both the reflection symmetry $\overline{u…

1+1 Dimensional Yang-Mills Theories in Light-Cone Gauge

A. Bassetto, G. Nardelli

In 1+1 dimensions two different formulations exist of SU(N) Yang Mills theories in light-cone gauge; only one of them gives results which comply with the ones obtained in Feynman g…

SLD Collaboration, K. Abe, I. Abt

We present the first measurement of the left-right charge asymmetry A_Q^{obs} in hadronic Z boson decays. This was performed at E_cm = 91.27 GeV with the SLD at the SLAC Linear Col…

On the BRST Quantization of the Massless Bosonic Particle in Twistor-Like Formulation

Igor Bandos, Alexey Maznytsia, Igor Rudychev +1

We study some features of bosonic particle path-integral quantization in a twistor-like approach by use of the BRST-BFV quantization prescription. In the course of the Hamiltonian…
