 FIRENZE FI11 2005 PROGRAM
 =========================

New researchers: 
A. Antoniazzi, Ph-D student; A. Pronko and R. Zillmer, INFN Postdocs;
L. Casetti, University permanent researcher.


- A. Cappelli, M. Riccardi, G.R. Zemba
``Noncommutative field theories and the quantum Hall effect''
Analyze the description of the Laughlin Hall state in terms of
the non-commutative Chern-Simons field theory as proposed by L. Susskind
in 2001: quantization of the corresponding Chern-Simons Matrix Model.
Study the quantum mechanics of electrons in the Landau levels when
one introduces a further non-commutatitivity among the coordinates.

- A.Cappelli, G. D'Appollonio, P. Pearce
``Boundary conformal field theories''
Study the renormalization-group flows that change the boundary conditions
in a conformal invariant theory, that are relevant for tachyon
condensation in string theory. Similar analysis of the defect lines 
that can be introduced in the conformal theory.
 
- F. Colomo, A. G. Pronko
``Finite-size corrections to the Partition Function of the 6-vertex model''
The six vertex model with domain wall boundary condition is interesting for
its deep connection with the theory of alternating  sign matrix and domino
tiling. The partition function is known only in the thermodynamic
limit, but we are computing the finite size corrections by representing
the partition function as a Freedholm determinant of an integral operator. 
We are moreover investigating exact evaluation of the partition function 
at some specific values of the deformation parameter of the model.

- M. Pettini, L. Casetti, R. Franzosi
``Topological theory of phase transitions''
The earlier explanation of the origin of phase transitions involving
concepts and methods of differential topology will be further developed. 
We shall investige the topology changes of equipotential submanifolds of
configuration space which entail a thermodynamic phase transition.
The description of first order, second order and glassy phase 
transitions within this differential-topological framework will be a main
research topic. 
    
- L. Casetti, M. Kastner 
``Topology and microcanonical phase transitions''  
We plan to investigate the relation between topology changes of submanifolds
of configuration and phase spaces from the microcanonical point of view.
This research will be pursued considering simple models as well as studying
general properties of classes of physical systems.

- A. Antoniazzi, S. Ruffo, M. Antoni, J. Barre', T. Dauxois, H. Hinrichsen,  
D. Mukamel 
``Dynamics and thermodynamics in systems with long-range interactions''
Long-range interactions (e.g. gravity and Coulomb interactions) lead to
inequivalences between the canonical and microcanonical ensambles and to
metastable states whose lifetime goes to infinity with the size of the system.
We want to derive the thermodynamic limit properties of systems with 
long-range interactions and to study the relaxation to equilibrium.
We have recently developed a general method, based on the theory of large
deviations, which allows to obtain the exact solution in the microcanonical
and canonical ensembles of a large class of models. 
The quasi-stationary states, whose relaxation time diverges with system size, 
have been related to stable stationary states of the Vlasov equation.
Next we would like to apply the large-deviation method to models describing 
more "realistic" systems possessing both long and short-range interactions.
Moreover, we would like to find a physical signature of the relaxation to 
quasi-stationary states: a first indication comes from
the analysis of the saturated state of the Free Electron Laser, as
described by the Colson-Bonifacio model.

- S. Ruffo, R. Khomeriki, S. Lepri
``Localized excitations in non-linear lattices''
Clusters of ``breathers'' can be produced in the FPU lattices by
exciting the modes at the band edges.

- F. Bagnoli, F. Franci, R. Rechtman
"Synchronization and impredictable behavior of nonchaotic systems"
We investigate the origin of unpredictability in extended systems
which are not chaotic from the usual point of view, and their 
synchronization properties. In particular, we would like to study the 
connection among damage spreading and our definition of finite-distance 
Lyapunov exponent in discrete systems (cellular automata) and coupled map
lattices. We would like to obtain informations about the chaotic properties 
of a system from its propension to synchronization with a replica of 
the system itself. 

- R. Livi, S.Lepri and A. Politi
"Study of transport in low-dimensional nonlinear and disordered systems"
We have pointed out the existence of the universality
classes characterizing the divergence of heat conductivity
for models in one space dimension.
We plan to study the anomalous heat transport in 
realistic models of polymers and carbon nanotubes.

- R. Livi, S. Lepri, F. Piazza and A. Politi
" Study of localization phenomena in the presence of nonlinearity"
We have understood the mechanism of spontaneous formation
of localized periodic solutions in anharmonic lattices.
We want to describe the appearance of
localized solutions induced by periodic perturbations applied
to the boundaries of anharmonic lattices.

- R. Livi, A. Politi, A. Torcini and R. Zillmer
"Dynamical approach to neural networks dynamics"
This is a new research line which is going to start
in fall 2004 in collaboration with the new INFN postdoc R. Zillmer.
We would like to characterize quantitatively
the robustness of information flow in single neurons 
and neural networks in the presence of noise.


- V.Tognetti, C.Biagini, A.Varlamov, L. Capriotti
"Quantum fluctuations in superconductors"
We have studied quantum fluctuations of magnetic conductivity in
two-dimensional superconductors, including doping effects.
We plan to further analyze transport properties (conductivity, Hall
conductivity, thermal conductivity) near the superconductor-insulator
transition driven by doping-induced disorder.

GENOVA FI11 2005 PROGRAM
========================

- N. Magnoli, M. Caselle, P. Grinza, R. Guida
``Massive deformations of conformal field theories''
In the framework of conformal perturbation theory we have studied, 
by using analytical and numerical techniques (TCS), the Ising model 
perturbed by the magnetic field on the plane and on the sphere.
For the future we plan study the 3-point function of magnetization 
operators in Potts model.


- B. Kramer, N. Magnoli, M. Sassetti
``Effective field theories of the quantum Hall effect''
In the framework of Chern-Simons Composite Fermions (CSCF) theories for
the Fractional Quantum Hall Effect (FQHE), we have studied  the effects of
interaction in a two-component Hall fluid at total filling factor 1,
addressing the competition between different paired states formation mechanisms.
We plan to investigate the issues of fractional charge and statistics for FQHE
quasiparticles, both with the CSCF approach and in the context of boundary
excitations described by the one-dimensional model of the Chiral Luttinger
Liquid.

TRIESTE FI11 2005 PROGRAM
=========================

New researcher: G. Niccoli, A. Michelangeli, new Ph-D students

Research activities:

   "Exact correlators and form factors in massive integrable models''
   Classification of the operators by the solution of the Watson
   equations of the form factors, study of the spectral series of
   correlation functions and their exact resummation.

   "Non-integrable quantum field theory''
   Study of the mass spectrum and correction to scattering amplitudes.
   Confinement of topological excitations and application to nonlinear
   sigma models with topologic terms within the framework of form factor
   perturbation theory applied to massless theories. Phase diagrams
   of several models, including Ising model and double-Sine Gordon

   "Semiclassical approach to quantum field theory"
   A new formulation of semiclassical methods relying on classical solutions
   of equations of motion allows the determination of finite size energies and
   quantum matrix elements. This method proves to be efficient to study
   non-integrable quantum field theories and field theories at finite volume.

   "Quantum field theory at finite temperature and finite volume''
   A new approach has been developed to deal with finite
   temperature problem. This consists in quantising the theory
   at finite volume by semi-classical method and extracting in
   this way the exact matrix elements in finite volume.
   Correlation functions can be recovered using their spectral
   representation.

   "Boundary Liouville theory and 2-D quantum gravity"
   Study of boundary correlation functions in Liouville theory
   and in solvable statistical models of 2D quantum gravity by means
   of functional equations.

   "Quasiparticle description of Conformal Field Theories"
    Alternative description of massless excitations with fractional
    statistics and fractional charges. This method shows interesting
    connections with lattice models such as Calogero-Sutherland.

   "Field theory of scaling lattice models''
    Computation of universal features of the scaling region, including
    the case of lines of critical points; study of
    the role of lattice symmetries in the continuum limit of
    critical antiferromagnets; numerical investigation of analytic
    properties through the truncated conformal space approach.

   "Boundary field theory and surface phase diagrams''
    Study of the effects induced on field theories and strongly
    correlated systems by the boundary conditions and their
    relative boundary flows.
