Research Interests

  • Strongly correlated quantum manybody systems

  • Quantum transport

  • Periodically driven manybody systems (Floquet physics)

  • Frustrated spin systems

  • Nanomagnets

  • Entanglement/ quantum information


Numerical techniques I use: Exact Diagonalization (ED), Density Matrix Renormalization Group (DMRG), etc.

Programming language: While doing numerical calculations, I usually write my own codes in FORTRAN.
