Research Areas

I work in theoretical physics with emphasis in strongly interacting electron systems. My research tools combine analytical methods with numerical techniques for describing static and dynamical properties of many-body systems. I am particularly interested in the novel states of matter that are realized in frustrated quantum materials. Quantum magnetism offers the simplest playground (purely bosonic systems) to study the multiplicity of exotic quantum states matter, ranging from multipolar orderings to spin liquids, that can emerge at low energies out of very simple competing interactions. I believe frustration is also a guiding principle for finding novel quantum states of matter in itinerant systems (metals), such unconventional superconductivity. For this reason, we are currently study the role of frustration in strongly correlated metals.

The dynamical response of interacting quantum systems offers an invaluable tool for detecting proximity to novel quantum states of matter, as well as for characterizing these states. Developing experimental and theoretical tools for studying dynamical responses of quantum materials is crucial for the development of our field. One of my current areas of research is the development of field theory techniques for computing dynamical responses of quantum magnets with strong quantum fluctuations. We are also developing new numerical algorithms for extending semi-classical approaches to itinerant systems. These tools are essential for interpreting neutron scattering data obtained at the Spallation Neutron Source of the Oak Ridge National Laboratory (ORNL). This is an example of the kind of synergistic activities that we are currently developing at Shull Wollan center (a joint institute for neutron sciences).
