Robin Schaefer

Computational Physicist

Hi, I’m Robin Schaefer, a condensed matter theorist currently working in Norman Yao’s lab at Harvard University.

My research focuses on frustrated magnetism, nonequilibrium dynamics, and chaos. I develop numerical methods for quantum many-body systems and use them to connect theory with experiment. One example is the search for quantum spin ice in dipolar-octupolar pyrochlores.

DanceQ

My computational efforts have resulted in the development of DanceQ, a high-performance C++ library for exact diagonalization of Hamiltonian and Lindbladian systems. It is designed for scalability using OpenMP and MPI.

PyGFMC

I also develop PyGFMC, a JAX-based Green’s function Monte Carlo code for sign-problem-free quantum lattice models. On GPUs it reaches nearly three orders of magnitude higher throughput than on CPUs. It is compatible with NetKet, enabling arbitrary neural quantum states as guides.
