Quantum Monte Carlo Simulations of the 2D Su-Schrieffer-Heeger Model
Bo Xing, Wei-ting Chiu, Dario Poletti +2
Over the last several years, a new generation of quantum simulations has greatly expanded our understanding of charge density wave phase transitions in Hamiltonians with coupling b…
Hybridization effect on the X-ray absorption spectra for actinide materials: Application to PuB
Wei-ting Chiu, Roxanne M. Tutchton, Giacomo Resta +5
Studying the local moment and 5-electron occupations sheds insight into the electronic behavior in actinide materials. X-ray absorption spectroscopy (XAS) has been a powerful to…
Electronic Correlation Induced Expansion of Compensated Electron and Hole Fermi Pockets in delta-Plutonium
Roxanne Tutchton, Wei-ting Chiu, R. C. Albers +2
Plutonium is a critically important material as the behavior of its 5f-electrons stands midway between the metallic-like itinerant character of the light actinides and localized at…
Charge Order in the Holstein Model on a Honeycomb Lattice
Y. -X. Zhang, W. -T. Chiu, N. C. Costa +2
The effect of electron-electron interactions on Dirac fermions, and the possibility of an intervening spin liquid phase between the semi-metal and antiferromagnetic (AF) regimes, h…
