ADM approach to 2+1 dimensional gravity
Pietro Menotti, Domenico Seminara
The canonical ADM equations are solved in terms of the conformal factor in the instantaneous York gauge. A simple derivation is given for the solution of the two body problem. A ge…
Aharonov-Bohm Effect in the Abelian-Projected SU(3)-QCD with -term
Dmitri Antonov
By making use of the path-integral duality transformation, string representation of the Abelian-projected SU(3)-QCD with the -term is derived. Besides the short-range (self-)int…
Confinement, Chiral Symmetry Breaking and Faddeev-Niemi Decomposition in QCD
Kenichi Konishi, Kazunori Takenaga
We identify two distinct, complementary gauge field configurations for QCD with SU(2) gauge group, one (instanton-like configurations) having to do with chiral symmetry breaking bu…
String Nature of Confinement in (Non-)Abelian Gauge Theories
Dmitri Antonov
Recent progress achieved in the solution of the problem of confinement in various (non-)Abelian gauge theories by virtue of a derivation of their string representation is reviewed.…
Many-Brane Extention of the Randall-Sundrum Solution
Hisaki Hatanaka, Makoto Sakamoto, Motoi Tachibana +1
Recently, Randall and Sundrum proposed a static solution to Einstein's equations in five spacetime dimensions with two 3-branes located at the fixed points of to solve th…
Orthogonal polynomial method and odd vertices in matrix models
E. Minguzzi
We show how to use the method of orthogonal polynomials for integrating, in the planar approximation, the partition function of one-matrix models with a potential with even or odd…
Infra-Red Asymptotic Dynamics of Gauge Invariant Charged Fields: QED versus QCD
E. d'Emilio, S. Micciche
The freedom one has in constructing locally gauge invariant charged fields in gauge theories is analyzed in full detail and exploited to construct, in QED, an electron field whose…
ADM approach to 2+1 dimensional gravity coupled to particles
Pietro Menotti, Domenico Seminara
We develop the canonical ADM approach to 2+1 dimensional gravity in presence of point particles. The instantaneous York gauge can be applied for open universes or universes with th…
Generalized Second Law in String Cosmology
Ram Brustein, Stefano Foffa, Riccardo Sturani
A generalized second law in string cosmology accounts for geometric and quantum entropy in addition to ordinary sources of entropy. The proposed generalized second law forbids sing…
Bosonization at Finite Temperature and Anyon Condensation
A. Liguori, M. Mintchev, L. Pilo
An operator formalism for bosonization at finite temperature and density is developed. We treat the general case of anyon statistics. The exact -point correlation functions, sat…
The Abelian Higgs Model as an Ensemble of Vortex Loops
Dmitri Antonov
In the London limit of the Ginzburg-Landau theory (Abelian Higgs model), vortex dipoles (small vortex loops) are treated as a grand canonical ensemble in the dilute gas approximati…
Yangian symmetry in the Non Linear Schrodinger hierarchy
M. Mintchev, E. Ragoucy, P. Sorba +1
We study the Yangian symmetry of the multicomponent Quantum Nonlinear Schrodinger hierarchy in the framework of the Quantum Inverse Scattering Method. We give an explicit realizati…
Loop corrections and graceful exit in string cosmology
Stefano Foffa, Michele Maggiore, Riccardo Sturani
We examine the effect of perturbative string loops on the cosmological pre-big-bang evolution. We study loop corrections derived from heterotic string theory compactified on a $Z_N…
On the Beta Function in Supersymmetric Gauge Theories
G. Carlino, K. Konishi, N. Maggiore +1
We re-examine perturbative and nonperturbative aspects of the beta function in N=1 and N=2 supersymmetric gauge theories, make comments on the recent literature on the subject and…
Spontaneous Supersymmetry Breaking from Extra Dimensions
M. Sakamoto, M. Tachibana, K. Takenaga
We propose a new spontaneous supersymmetry breaking mechanism, in which extra compact dimensions play an important role. To illustrate our mechanism, we study a simple model consis…
Spontaneously Broken Translational Invariance of Compactified Space
M. Sakamoto, M. Tachibana, K. Takenaga
We propose a mechanism to break the translational invariance of compactified space spontaneously. As a simple model, we study a real model compactified on $M^{D-1}\otimes S^1…
Monopole-like Excitations as a Source of Confinement in the SU(2)-Gluodynamics
Dmitri Antonov, Dietmar Ebert
By making use of the Abelian projection method, a dual version of the SU(2)-gluodynamics with manifest monopole-like excitations, arising from the integration over singular gauge t…
