Numerically exploring the 1D-2D dimensional crossover on spin dynamics in the doped Hubbard model
Y. F. Kung, C. Bazin, K. Wohlfeld +7
Using determinant quantum Monte Carlo (DQMC) simulations, we systematically study the doping dependence of the crossover from one to two dimensions and its impact on the magnetic p…
Characterizing the three-orbital Hubbard model with determinant quantum Monte Carlo
Y. F. Kung, C. -C. Chen, Yao Wang +6
We characterize the three-orbital Hubbard model using state-of-the-art determinant quantum Monte Carlo (DQMC) simulations with parameters relevant to the cuprate high-temperature s…
Doping evolution of spin and charge excitations in the Hubbard model
Y. F. Kung, E. A. Nowadnick, C. J. Jia +4
To shed light on how electronic correlations vary across the phase diagram of the cuprate superconductors, we examine the doping evolution of spin and charge excitations in the sin…
Numerical exploration of spontaneous broken symmetries in multi-orbital Hubbard models
Y. F. Kung, C. -C. Chen, B. Moritz +3
We study three proposals for broken symmetry in the cuprate pseudogap - oxygen antiferromagnetism, orbital loop currents, and circulating currents involving apex oxygens -…
Persistent spin excitations in doped antiferromagnets revealed by resonant inelastic light scattering
C. J. Jia, E. A. Nowadnick, K. Wohlfeld +6
How coherent quasiparticles emerge by doping quantum antiferromagnets is a key question in correlated electron systems, whose resolution is needed to elucidate the phase diagram of…
Determinant quantum Monte Carlo study of the two-dimensional single-band Hubbard-Holstein model
S. Johnston, E. A. Nowadnick, Y. F. Kung +3
We have performed numerical studies of the Hubbard-Holstein model in two dimensions using determinant quantum Monte Carlo (DQMC). Here we present details of the method, emphasizing…
Time-Dependent Charge-Order and Spin-Order Recovery in Striped Systems
Y. F. Kung, W. -S. Lee, C. -C. Chen +4
Using time-dependent Ginzburg-Landau theory, we study the role of amplitude and phase fluctuations in the recovery of charge and spin stripe phases in response to a pump pulse that…
Real-time manifestation of strongly coupled spin and charge order parameters in stripe-ordered nickelates via time-resolved resonant x-ray diffraction
Y. D. Chuang, W. S. Lee, Y. F. Kung +27
We investigate the order parameter dynamics of the stripe-ordered nickelate, LaSrNiO, using time-resolved resonant X-ray diffraction. In spite of distinct spi…
Doping Evolution of Oxygen K-edge X-ray Absorption Spectra in Cuprate Superconductors
C. -C. Chen, M. Sentef, Y. F. Kung +5
We study oxygen K-edge x-ray absorption spectroscopy (XAS) and investigate the validity of the Zhang-Rice singlet (ZRS) picture in overdoped cuprate superconductors. Using large-sc…
Phase Fluctuations and the Absence of Topological Defects in Photo-excited Charge Ordered Nickelate
W. S. Lee, Y. D. Chuang, R. G. Moore +32
The dynamics of an order parameter's amplitude and phase determines the collective behaviour of novel states emerged in complex materials. Time- and momentum-resolved pump-probe sp…
