Anomalous Magnetoresistance due to Longitudinal Spin Fluctuations in a Jeff = 1/2 Mott Semiconductor
Lin Hao, Zhentao Wang, Junyi Yang +12
As a hallmark of electronic correlation, spin-charge interplay underlies many emergent phenomena in doped Mott insulators, such as high-temperature superconductivity, whereas the h…

Real space Berry curvature of itinerant electron systems with spin-orbit interaction
Shang-Shun Zhang, Hiroaki Ishizuka, Hao Zhang +2
By considering an extended double-exchange model with spin-orbit coupling (SOC), we derive a general form of the Berry phase that electrons pick up when moving around a closed…

Spinon Confinement and a Sharp Longitudinal Mode in YbPtPb in Magnetic Fields
W. J. Gannon, I. A. Zaliznyak, L. S. Wu +7
The fundamental excitations in an antiferromagnetic chain of spins-1/2 are spinons, de-confined fractional quasiparticles that when combined in pairs, form a triplet excitation con…
