The ever-increasing global energy need and its impact on climate change have motivated intensive research in various renewable energy alternatives.  Among these include energy conversion from sources such as the sun and wind, to name a few.  In addition, the storage of energy via clean methods is equally important.  The use of rechargeable batteries, like lithium ion batteries (LIBs), has proven to be the technology of choice.  LIBs are rechargeable, electrochemical storage devices that have gained significant attention and now serve as an integral power source for many of today’s portable electronics and automobiles.

Today, lithium iron phosphate battery systems are very attractive but are hindered by constraints due to its poor lithium ion diffusion dynamics and extremely low electronic conductivity.  The battery research group is exploring advanced lithium ion material compositions using nanomaterials such as metallic nanoparticles, carbon nanotubes, carbon nanofibers and graphene.  The overarching goal of the renewable energy researchers is to overcome challenges which impede the practical applications of LIBs.

The Computational Simulations in Condensed Matter Group led by Dr. Silvina Gatica focuses on applying molecular simulation techniques, such as Monte Carlo and Molecular Dynamics, along with Quantum Mechanics and Statistical Mechanics, to study physical adsorption in nano-porous materials. These nano-scale studies are designed to investigate the properties of the adsorbed matter and to assess materials for specific applications, such as gas storage and gas separation.

Quantum materials are a class of materials where better understanding of unique quantum phenomena, such as entanglement, correlation and coherence, are necessary to explain their physical properties over a wider range of energy and length scales. Examples of quantum materials include magnets, superconductors, topological insulators, graphene, etc.

The Quantum Materials Modeling Lab (QM²L) is led by Dr. Sugata Chowdhury. The QM²L general area of expertise is in theoretical and computational materials science. Dr. Chowdhury’s research group’s research interests are to study emergent behaviors and new exotic quantum states of magnetic and non-magnetic quantum materials. These novel materials might open new research directions and eventually lead us to optimized high-quality and energy-efficient nanodevices and renewable energy sources. In general, my current research works can be divided into four different arears: (1) Magnetic Quantum Materials; (2) Catalysis; (3) Materials Repository, and (4) Non-linear Optical Properties.

Research activities in this group focus on the most basic building blocks of Nature and their mutual interactions, as well as the development of the theoretical and mathematical techniques used to this end. This includes but is not limited to the study of:

1. the physical spacetime in string theory and its M- and F-theory extensions,
2. geometry and topology of spacetime, esp. algebraic geometry and group theory,
3. supersymmetry, its representations, applications in physics and its breaking,
4. the origins and properties of dark matter and dark energy.
