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…
Surface Phase Diagrams from Nested Sampling
Mingrui Yang, Livia B. Pártay, Robert B. Wexler
Studies in atomic-scale modeling of surface phase equilibria often focus on temperatures near zero Kelvin due to the challenges in calculating the free energy of surfaces at finite…
Validating phase-space methods with tensor networks in two-dimensional spin models with power-law interactions
Sean R. Muleady, Mingru Yang, Steven R. White +1
Using a recently developed extension of the time-dependent variational principle for matrix product states, we evaluate the dynamics of 2D power-law interacting XXZ models, impleme…
Detecting emergent continuous symmetries at quantum criticality
Mingru Yang, Bram Vanhecke, Norbert Schuch
New or enlarged symmetries can emerge at the low-energy spectrum of a Hamiltonian that does not possess the symmetries, if the symmetry breaking terms in the Hamiltonian are irrele…
Stochastic differential equation approach to understanding the population control bias in full configuration interaction quantum Monte Carlo
Joachim Brand, Mingrui Yang, Elke Pahl
We investigate a systematic statistical bias found in full configuration quantum Monte Carlo (FCIQMC) that originates from controlling a walker population with a fluctuating shift…
