I am interested in phase transitions and critical phenomena in disordered systems. In a recent project, I studied the interplay between quantum fluctuations and geometric randomness in two-dimensional Heisenberg antiferromagnets with inhomogeneous bond dilution, and found an interesting quantum disordered phase.
