Theoretical particle physics has advanced its frontiers enormously in
recent years. The success of the Weinberg-Salam model of electroweak
interactions, culminating in the discovery of the W^{+/- }and
Z^{o}, has led to efforts to find a unified theory including quantum
chromodynamics and perhaps general relativity as well. A theory of all
interactions and particles usually has far-reaching implications, for instance
predicting proton decay, and affecting the development of the universe in the
first few moments after the big bang. Thus particle physics now relates to
problems in cosmology, such as galaxy formation and the observed predominance
of matter over antimatter. The most ambitious of these unified theories -
superstrings - is being intensively studied at Rutgers, which has one of the
strongest particle theory groups in the world. Other problems, such as
developing methods to study non-abelian gauge theories in nonperturbative
regimes, electroweak baryogenesis, and computational methods, are also being
studied. Advances in the understanding of field theory have yielded techniques
and predicted phenomena which are relevant to mathematics, statistical
mechanics, and condensed matter physics.

**Professor Tom Banks**

Since 1996 I have been primarily working on the nonperturbative formulation of superstring theory invented by Steve Shenker, myself and our collaborators. This defines string theory as the limit of quantum mechanical systems whose basic variables are matrices, and incorporates many of the results of string duality. I retain my interests in supersymmetric field theory, supersymmetry phenomenology, and cosmology.

**Professor John Bronzan**

My current interest is in non-pertubative Hamiltonian QCD and related field theories.

**Professor Diuliu-Emanuel Diaconescu**

My research is in string theory as a theory of fundamental interactions and quantum gravity, and in non-perturbative methods in field theory. I am currently studying large N field theories, to develop ideas for the non-perturbative definition of string theories, and for possible application to QCD physics. I also work on supersymmetric gauge theory and on conformal field theory, and I maintain an interest in computational techniques for theoretical physics.

**Professor Daniel Friedan**

I work on two projects: one concerning the fundamental laws of physics,
the other concerning certain condensed matter systems that might
eventually be useful in quantum computers. Both projects use the
technology of two-dimensional quantum field theory.
I have formulated and am investigating a physical mechanism that at
least formally determines the background spacetime for string theory.
The hope is that this mechanism will actually produce the combination of
General Relativity and the Standard Model of particle physics that has
so accurately described physics across an astonishingly wide range of
distance scales.
I am also trying to understand the basic properties of near-critical
quantum circuits. These are one-dimensional condensed matter systems
near a low temperature critical point. I have argued that such systems
are the only physical systems that are practical for asymptotically
large-scale quantum computers.
These systems behave in universal ways which are described by 1+1
dimensional quantum field theories. Universal physical properties of
these systems can be discovered by investigating the general structures
of 1+1 dimensional quantum field theories.

**Professor Claud Lovelace**

I am working on string field theory. Long ago, when I
discovered the critical dimension (Phys.Lett.B34,500(1971)),
I showed that strings can lead to a composite graviton.
Witten (Nucl.Phys. **B268**, 253, 1986) took this much further
by proving that a field theory of open strings can generate
the complete perturbation expansion. Unfortunately there
are severe mathematical and computational difficulties,
and further progress has been slow. If this approach could
be fully realized, it would imply the astonishing conclusion
that we actually live in 10 flat dimensions, and the world
we see is an illusion created by the deformation of our
measuring instruments by matter fields. There have been
many related speculations that black holes require a form
of holography, but this would go further. A paper I wrote
with D.Belov (hep-th/0304158) solves one mathematical difficulty,
but far more work is needed.

** Professor Sergei Lukyanov**

My research activities are in the areas of quantum field theory, mathematical physics and statistical mechanics. Currently I am mostly interested in exactly soluble low dimensional models.

**Professor Gregory Moore**

My area of specialization is Field Theory and I am mostly interested in its non-perturbative aspects.

**Professor **
**Joel Shapiro**

My work has been centered primarily on string theory, especially the understanding of closed strings as they appear in an open string theory, and of the Green-Schwarz string in curved superspace backgrounds, and the connection of the necessary constraints on such backgrounds with supergravity.

**Professor Scott Thomas**

I am working on quantum field theory in relation to both high-energy physics and statistical physics. More specifically, I am looking for exact solutions to model quantum field theories, and trying to elaborate mathematical structures of such solutions as well as applications to physics of criticality, strings and gravity. Presently I am interested in various aspects of the fascinating interplay between integrable field theories, conformal field theories, and string theory.
