Overview

According to the official faculty page, Yin Zhong works in condensed matter theory, using theoretical physics methods to study the basic properties and laws of condensed matter systems, especially strongly correlated electron systems. Representative material settings include cuprate superconductors, iron-based superconductors, transition-metal oxides, and heavy-fermion systems dominated by f-electrons. Topics include Mott insulators, quantum spin liquids, unconventional superconductivity, stripe phases, non-Fermi liquids, and topological order. :contentReference[oaicite:18]{index=18}

Analytical Methods

Frequently used analytical approaches include slave-particle mean-field theories, field-theoretic methods such as Feynman-diagram calculations and path-integral approximations, and truncated equations of motion for Green functions together with strong-coupling expansion. Certain specially designed models, such as the Kitaev model or Hatsugai–Kohmoto model, may even admit exact solutions. :contentReference[oaicite:19]{index=19}

Numerical Methods

Numerical work includes exact diagonalization and quantum Monte Carlo, especially determinant quantum Monte Carlo for lattice fermion systems. In cases with a severe sign problem, more advanced techniques such as DMRG and tensor-network approaches may become necessary. :contentReference[oaicite:20]{index=20}
