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…

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…

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…

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…

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…
