About

In general, I am interested in strongly-interacting quantum many-body condensed-matter systems, explored by non-perturbative methods:

Geometry of the fractional quantum Hall effect (FQHE):  The  FQHE occurs when the kinetic energy of electrons bound to a 2D surface becomes quantized in the presence of a high magnetic fields when they move in Landau orbits.  The "guiding centers" of their orbits  have non-commuting components and define a "quantum geometry".     "Incompressible quantum fluid" states of the electrons  at fractional Landau-level filling p/q can be modeled as a "condensate" of "composite bosons" formed from p particles and q "flux quanta" (guiding-center orbitals).
