The PITP Research Networks from 20032008 covered all areas of
Theoretical Physics. Their activities and membership are
described below.
The New PITP research networks (from 2009 onwards) concentrate
on the general area of Complex Systems, including condensed
matter physics, as well as complex materials (including polymer
physics and biophysics), quantum optics, and topics in theoretical
quantum chemistry. These networks are in the process of formation
at the current time.
A list of all pre2009 PITP researchers is available by
location.
Quantum Condensed Matter
Study of collective quantum phenomena in stronglycorrelated systems at
low temperatures from atomic to mesoscopic scales.

Strings and Particles
Questioning the very structure and origin of the universe,
the nature of the constituents of all matter and their interactions.

Complex Systems
Unifying physics, chemistry, and biology with ideas from
of the study of complex
physical and biological systems, often far from equilibrium, and the
dynamics of complex networks 
Gravity, Cosmology & Theoretical Astrophysics
From the study of the early universe to work in quantum
gravity leading to questions about the foundations of quantum mechanics,
and quantum information
