Vasilopoulos Research Group

Our current research can be broadly characterized as

Transport and many-body effects in nanostructures of Dirac materials.

We theoretically study (magneto)transport properties, e.g., spin-Hall effect, quantum Hall effect, optical absorption, etc., in novel graphene-like nanostructures, also known broadly as Dirac materials, and Floquet topological insulators. The combinations of different Dirac materials are known or referred to as van der Waals heterostructures. We also study thermal transport, and collective excitations, e.g., plasmons, surface plasmons, etc., in the same structures.

All studies focus on various ways to control transport in these materials and obtain results pertinent to the development of novel electronic, spintronic and valleytronic devices.

Some explicit research topics of the group are:

1. Transport and many-body effects in transition-metal-dichalcogenides,
2. Semimetal states and Coulomb screening in black phosphorus and Weyl materials and
3. Atomic collapse in Dirac materials, influence on transport.
