The research in Professor Nandini Trivedi’s group focuses on the effects of strong interactions in condensed matter systems and ultracold atoms in optical lattices. The basic idea is to understand how electrons and atoms get organized at very low temperatures and how new phases of matter emerge. For example, we examine quantum phase transitions between superfluids and Mott insulators in optical lattices and also how fermions become entangled into novel spin liquid states.

Materials systems with many strongly interacting degrees of freedom can host some of the most exotic physical states known, ranging from superconductivity to topological phases. 

One of the hallmarks of these quantum materials is the ability for a small perturbation to dramatically change the ground state. In thin films, the interface between two distinct materials forms a playground to engineer such emergent states. Specifically—and in contrast to bulk crystals—such an abrupt heterointerface can utilize the broken symmetry/reduced dimensionality inherent to the interface as well as induce chemical potential offsets, epitaxial strain and provide proximity to functional phases. 

Work in the Mundy group will design, synthesize and probe such emergent phenomena in complex oxide thin films. Initial efforts will be particularly focused on using thin film epitaxy to construct metastable materials, with an emphasis on materials with strong spin frustration/exotic magnetic properties and novel superconductors.

Dr. Mandrus uses the experimental tools of materials synthesis and crystal growth to address cutting-edge issues in materials physics.  Recent interests include: (1) discovery and characterization of new chiral ferromagnets that may display electronic liquid-crystal phases; (2) discovery and characterization of new iridates in which strong spin-orbit coupling leads to Mott-Hubbard physics; (3) mixed phase phosphate electrolytes for intermediate temperature fuel cells.  Long standing interests include: (1) discovery and characterization of new unconventional superconductors; (2) discovery and characterization of new collective phenomena in transition metal oxides, especially involving slow dynamics, (3) neutron scattering investigations of exotic magnets, and (4) new materials for thermoelectric refrigeration and power generation.

Our overarching goal is to define the mechanisms by which microbes interact with and manipulate their environment, with the ultimate goal of engineering these interactions to control microbial pathophysiology and ecology.

Our research is focused on how microbes use electron transfer via hair-like protein appendages called pili for communication, survival and biofilm formation.

Many new electronic devices require sophisticated thin film processing techniques. For example, ultra thin films or superlattices may require the thickness controlled down to one unit cell; other devices may need the lateral dimensions to be patterned down to submicron or smaller sizes. Oxide materials possess an enormous range of electrical, optical, and magnetic properties.

For instance, insulators, high quality metals, dielectrics, ferroelectrics, piezoelectrics, semiconductors, ferromagnetics, transparent conductors, colossal magnetoresistance materials, superconductors, and nonlinear optic materials have all been produced using oxide materials.

Therefore, thin films and heterostructures of oxide materials have great potential for novel device applications. My main area of interest is the synthesis and characterization of epitaxial oxide heterostructures uniquely suited for electronic, magnetic, piezoelectric, and high T c superconducting devices. I am also interested in epitaxial oxide superlattices consisting of two or more materials combined at nanoscale thickness.
