Hitesh J. Changlani

I am a theoretical and computational condensed matter physicist. From August 2018 - 2024, I was an Assistant Professor at Florida State University. I am currently an Associate Professor.

I am interested in the study of quantum systems of many strongly interacting particles (such as bosons, fermions, and spins). Several physical phenomena at low temperatures arise out of the intricate interplay of quantum mechanics and strong correlations.  Broadly, my research interests fall into the following categories:

• Mott insulators and "frustrated" magnets with a strong emphasis on experimentally relevant materials (also see 1, 2, 3, 4, 5, 6)  

• Development and application of novel numerical algorithms for the quantum many body problem (tensor networks and quantum Monte Carlo)

•  Multi-scale modeling of quantum matter with effective Hamiltonians from "density matrix downfolding" (also see this)

•  Physics of dilution and disorder, especially in magnets

•  Quantum information and entanglement, mutual information and density matrix based metrics 

My publications and preprints are available on the arXiv and google scholar. Feel free to contact me at hchanglani at fsu dot edu or hchanglani at magnet dot fsu dot edu.
