Our group is interested in topics related to quantum magnetism, superconductivity, and nanotechnology. We investigate microscopic models of interacting electronic systems, and use numerical techniques, such as Quantum Monte Carlo and Exact Diagonalization, to find their phase diagrams, ground state properties, and excitation spectra. Recently, we have applied the Stochastic Series Expansion Method to study field induced phase transitions in quantum spin liquids, developed optimization algorithms to construct nano-scale opto-electronic devices, and applied BCS theory to investigate the consequences of unconventional superconductivity in strongly correlated materials. Our work is motivated by and connected to recent experiments in the fields of quantum antiferromagnetism, high-temperature and heavy-fermion superconductivity, and nano-photonics.
