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…
Phonon dispersion and the competition between pairing and charge order
Natanael C. Costa, T. Blommel, W. -T. Chiu +2
The Holstein Model (HM) describes the interaction between fermions and a collection of local (dispersionless) phonon modes. In the dilute limit, the phonon degrees of freedom dress…
Pressure Effects on the 4f Electronic Structure of Light Lanthanides
W. -T. Chiu, D. R. Mortensen, M. J. Lipp +7
Using the satellite structure of the line in non-resonant x-ray emission spectra, we probe the high-pressure evolution of the bare 4f signature of the early light lan…
Magnetic Correlations in a Periodic Anderson Model with Non-Uniform Conduction Electron Coordination
Nicole Hartman, WeiTing Chiu, Richard Scalettar
The Periodic Anderson Model (PAM) is widely studied to understand strong correlation physics and especially the competition of antiferromagnetism and singlet formation. Quantum Mon…
