A universal description of Mott insulators: Characterizing quantum phases beyond broken symmetries
Matheus de Sousa, Zhiyu Fan, Wei Ku
Using Mott insulators as a prototypical example, we demonstrate a dynamics-based characterization of quantum phases of matter through a general N-body renormalization group framewo…

Bogoliubov quasi-particles in superconductors are integer-charged particles inapplicable for braiding quantum information
Zhiyu Fan, Wei Ku
We present a rigorous proof that under a number-conserving Hamiltonian, one-body quasi-particles generally possess quantized charge and inertial mass identical to the bare particle…

Pressure-induced trans-proximate correlation in LaNiO and possible routes to enhance its superconductivity
Ruoshi Jiang, Zhiyu Fan, Bartomeu Monserrat +1
We report an unexpected trans-proximate interlayer correlation (stronger correlation between disjoint layers than the adjacent ones) in the high-pressure phase of the recently disc…
