Excited states from local effective Hamiltonians of matrix product states and their entanglement spectrum transition
Denise Cocchiarella, Mingru Yang, Yueshui Zhang +3
Solving excited states is a challenging task for interacting systems. For one-dimensional critical systems, however, excited states can be directly accessed from the eigenvectors o…

Beyond fragmented dopant dynamics in quantum spin lattices: Robust localization and non-Gaussian diffusion
Mingru Yang, Sajant Anand, Kristian Knakkergaard Nielsen
The motion of dopants in magnetic spin lattices has received tremendous attention for at least four decades due to its connection to high-temperature superconductivity. Despite the…
