The chiral transition in two-flavor QCD
M. D'Elia, A. Di Giacomo, C. Pica
QCD with N_f=2 is a specially interesting system to investigate the chiral transition. The order of the transition has still not been established. We report the results of an in-de…
Tight contact structures on some small Seifert fibered 3--manifolds
Paolo Ghiggini, Paolo Lisca, Andras I. Stipsicz
We classify tight contact structures on the small Seifert fibered 3--manifold M(-1; r_1, r_2, r_3) with r_i in (0,1) and r_1, r_2 \geq 1/2. The result is obtained by combining conv…
A numerical approach to copolymers at selective interfaces
F. Caravenna, G. Giacomin, M. Gubinelli
We consider a model of a random copolymer at a selective interface which undergoes a localization/delocalization transition. In spite of the several rigorous results available for…
Index theorems for holomorphic self-maps
Marco Abate, Filippo Bracci, Francesca Tovena
Let be a complex manifold and a (possibly singular) subvariety of . Let be a holomorphic map such that restricted to is the identity. W…
Aspects of Finite Temperature Quantum Field Theory in a Black Hole Background
Giuseppe Milanesi, Mihail Mintchev
We quantize a scalar field at finite temperature T in the background of a classical black hole, adopting 't Hooft's ``brick wall'' model with generic mixed boundary conditions at t…
Signal Processing in the PVLAS Experiment
E. Zavattini, G. Zavattini, G. Ruoso +10
Nonlinear interactions of light with light are well known in quantum electronics, and it is quite common to generate harmonic or subharmonic beams from a primary laser with photoni…
