Hi, I'm Abhisek,
welcome to my webpage! I am a theoretical physicist, currently working at The Ohio State University.
My research interests lie in Condensed Matter Physics, with a focus on strongly correlated quantum many-body systems. When a large number of quantum particles come together and interact, their collective behavior gives rise to various “emergent” phases, such as magnetic, insulating, topological or even novel superconducting states. I study such phenomena theoretically in quantum materials, with applications ranging from high-temperature superconductors to the design of quantum devices and technologies for quantum information.
My research spans a broad area of condensed matter physics, employing a variety of modern analytical and computational techniques. These include methods borrowed from quantum field theory and statistical mechanics tools, such as classical and quantum Monte Carlo simulations.
In addition to addressing purely theoretical questions, I enjoy collaborating with experimentalists to connect theory with real-world observations.
Specific Research Topics:
- Superconductivity in thin-films and nanowires: Role of disorder and fluctuations
- Quantum transport theory: Calculation of Hall, thermopower, Nernst coefficients
- Quantum Hall Effects
- Entanglement, thermalization and Many-body localization (MBL)
- Quantum oscillations in Kondo insulators
- Sachdev-Ye-Kitaev (SYK) model and Large-N theories
- Quantum criticality in compressible lattice; Renormalization Group (RG) analysis
