Strongly coupled field theories in antide Sitter
space 
I will discuss work in progress on strongly coupled
field theories on antide Sitter space. These are interesting in
their own right, as the antide Sitter space provides a natural IR
cutoff. They are also interesting in the context of the AdS/CFT
correspondence, in two directions. Strongly coupled field theories on
D dimensional AdS space can have (D+1) dimensional gravitational
duals. And, if such theories appear as part of a gravitational
background, they could be dual to conformal field theories in (D1)
dimensions. I will focus on two main examples, the d=4 N=4 SYM theory
on AdS_{4}, and confining field theories on AdS space.

Evolution charged domain wall networks 
The standard lore of domain wall evolution is that
they scaling with the number of walls being inversely proportional to
time. We will show how this can be very different is the domain wall
forming field is coupled to the an unbroken U(1) field which generates a
Noether current. The natural propensity of loops of wall to collapse
under their own tension is resisted by the current leading to the
possibility of glasslike configurations of walls.

Integrability for scattering amplitudes in planar
N=4 super YangMills 
Tremendous progress in computing perturbative
scattering amplitudes in N=4 supersymmetric gauge theory has been made
over the past few years. Importantly the planar amplitudes appear to
display a dual conformal invariance next to the usual conformal
symmetry. Altogether the symmetry enlarges to a Yangian algebra known
from the context of integrable models. This infinitedimensional
symmetry might have the power to completely fix the Smatrix by
algebraic means.
In this talk we review the above developments. We then discuss conformal
symmetry for tree and loop scattering amplitudes. It turns out that the
free conformal symmetry generators are anomalous which calls for
certain deformations to make the symmetries exact. These relate
amplitude with different numbers of legs, and thus they contribute
substantially to a complete algebraic determination.

Surprises in the Wilson loop/Amplitude Duality 
MHV Amplitudes in planar N=4 super YangMills are
conjectured to be equal to lightlike polygonal Wilson loops at all
orders in perturbation theory. In this talk we discuss recent progress
and results at twoloop order and at weak coupling. Usually the duality
is expressed in terms of fourdimensional quantities. We demonstrate the
completely unanticipated fact that the equality continues to hold at
two loops through order epsilon in dimensional regularization for the
four and fiveparticle amplitudes.

Instantons in dimensions greater than 4 
Generalisations of the 4dimensional antiselfdual
YangMills equation to dimensions up to and including 8 have been known
since the early eighties. These equations have subsequently found
applications in string compactifications, in DonaldsonThomas theory,
and in KapustinWitten's work on the geometric Langlands program. In
flux compactifications, one is particularly interested in manifolds with
torsionful Gstructures: I will discuss examples of solutions on such
manifolds. For certain kinds of torsion, the instanton equations have
interpretation as gradient and Hamiltonian flows.

The physics of zero energy modes: Fractional
Charge 
(Joint work with SoYoung Pi)
A "Dirac"  type equation, i.e. a matrix equation with firstorder
derivatives, usually possesses positive and negative energy
eigenvalues. In the vacuum the former are empty and the latter are
filled. However it may happen that when the "Dirac" equation is
considered in a topologically nontrivial background, it possesses
zeroenergy eigenvalues. The question then arises whether in the vacuum
these zeroenergy states are empty or filled. Analysis of this question
results in the conclusion that the charge or the number eigenvalue
becomes fractional.

Vortices and complex geometry 
I will discuss the interplay of the physics and
mathematics of abelian Higgs vortices on a compact Riemann surface. When
the surface is large, the vortices behave like particles. When the
surface is small, and can only just accommodate the vortices (the
Bradlow limit), the vortices reduce to divisors on the Riemann surface,
and their fields can be described using classical, holomorphic concepts
like abelian differentials. The metric on the 1vortex moduli space can
be computed in both limits.

Talk: Nonlinear excitations as tools to analyze
DNA thermodynamics and dynamics. 
DNA is not the static object that structural images show. It is a highly
dynamical molecule. The base pairs, which encode the genetic
information,
fluctuate widely. The lifetime of a base pair, i.e. the time during
which it
stays closed, is only of the order of a few milliseconds. At high
temperature
some parts of the double helix open locally and form the so called
'denaturation bubbles', which play a role in biological function.
When it is viewed at the scale of base pairs, DNA appears as a nonlinear
lattice. There are certainly no solitons in DNA but nonlinear localized
excitations are nevertheless very helpful to analyze its properties.
Computing the free energy of the 'domain walls', which separate open and
closed regions, we can predict the temperature at which the two strands
fully
separate due to thermal fluctuations (the 'melting' transition of DNA)
with
a much better accuracy than with the standard methods of statistical
physics.
The local fluctuations of the double helix can be described in terms of
localized modes (discrete breathers) but establishing a satisfactory
model is
a challenge because the accurate experiments which can be performed on
this
molecule impose severe constraints on the models. The analysis of
the time scales of the fluctuations led us to a model that sustains a
new
class of discrete breathers.

Talk: Effects of strong magnetic field in lattice
QCD 
In the noncentral heavy ion collisions a very
strong magnetic field can be generated and the interference of strong
and electromagnetic interactions produce various physical effects. We
use the chirally invariant lattice Dirac operator to study gluodynamics
in the strong magnetic field. The observed effects are: the enhancement
of the chiral condensate, magnetization of the vacuum (spins of the
virtual quarks turn parallel to the external field), the local
generation of the anomalous quark electric dipole moment along the
magnetic field, the chiral magnetic effect (a CPodd generation of the
electric current of quarks directed along the magnetic field), existence
of nonzero electric conductivity along the direction of the field (the
vacuum becomes an anisotropic conductor).

QCD topology and RHIC experiments 
The first half of the talk is related with
confinement problem and its relation to instantons/dyons/monopoles: one
new element is lattice study of the monopole clustering
which provides clear evidence of their Bose condensation exactly at Tc.
The second tells about
several topologyrelated issues of the RHIC program.
QCD sphalerons and RHIC experiment aimed at observing them directly in
doublediffractive pp
collisions. The so called Magnetic Chiral Effect looks for CPodd
domains inside the QGP produced
in heavy ion collisions. Finally, there are evidences of flux tubes
preserved in hot matter, confirming
a view that nearTc matter is basically a plasma of magnetic objects.

Ysystems and spin chains 
There is an intriguing fact that transfer matrices
of
integrable spin chains and Tfunctions that follow from the
thermodynamic Bethe Ansatz obey the same Hirota equations. It is
therefore natural to ask the question if these two originally
different objects coincide. We will consider two different examples
trying to answer this question. For one case the answer is "yes". For
another one the answer is not clear, and there are arguments that
favor the negative answer.

Large N volume independence in conformal and
confining gauge theories 
In the large N limit, gauge theories compactified on
R^{dk} × (S^{1})^{k} are independent of the S^{1}
radii provided the theory has unbroken center symmetry.
This implies that a large N gauge theory which, on R^{d}, flows
to an IR fixed point retains the infinite correlation length and other
scale invariant properties even when toroidally compactified. Numerical
studies to determine the conformal window boundary may, in the large N
limit, be performed on onesite lattice models. Large N QCD with
massive adjoint fermions, when toroidally compactified, has a rich phase
structure with infinitely many phase transitions coalescing in the zero
radius limit.
