Our research topics broadly cover the realm of interacting condensed matter systems. The topics are constantly evolving with time, keeping up with the latest developments, and focusing on our interests and expertise. The topics we are mostly interested in are
Correlated materials: These are condensed matter systems where the interaction between particles (e.g. el-el interactions) is significant. A theoretical understanding of them requires careful handling of interactions by analytical methods such as diagrammatic perturbation theory, renormalization groups, etc. In particular, quantum field theory methods can be quite useful in order to understand the behavior of interacting electrons in solids.
Topological materials: These are insulators, semimetals, and superconductors whose electronic structures are characterized by nonzero integers known as topological invariants. Topological invariants often manifest themselves through unusual electronic states localized at sample boundaries. Since last two decades, these materials have been a field on intensive research activities.
Quantum magnetism: Magnetism, which has continued to be studied since centuries, is inherently quantum mechanical. In our group, we study the magnetic behavior of various condensed matter systems having itinerant or localized electrons.
