The condensed matter theory group at BGU conducts research in mesoscopic physics, disordered and strongly correlated systems. Of special interest are topics such as superconductivity, phase transitions, quasicrystals, liquid crystals, quantum dots, Kondo effect, persistent currents, quantum Hall effect, dephasing, dissipation and the relation to quantum chaos.

The group is also involved in multidisciplinary research, in the context of the newly established [Ilse-Katz Center for Meso and Nanoscale Science and Technology], involving scientists from the departments of Physics, Chemistry, Biotechnology and Chemical Engineering at Ben-Gurion University. The group has strong interactions with other groups in Israel and in the world.

There are weekly condensed matter seminar and a nanotechnology workshop.

The group participates in organizing conferences and workshops in Israel.
