Non-Fermi Liquid behavior at the Orbital Ordering Quantum Critical Point in the Two-Orbital Model
Ka Wai Lo, Wei-Cheng Lee, Philip W. Phillips
The critical behavior of a two-orbital model with degenerate and orbitals is investigated by multidimensional bosonization. We find that the corresponding bosonic…
Spectroscopic Imaging Scanning Tunneling Microscopy as a Probe of Orbital Structures and Ordering
Wei-Cheng Lee, Congjun Wu
Unlike charge and spin, the orbital degree of freedom of electrons in transition metal oxides is difficult to detect. We present the theoretical study of a new detection method in…
Berry Phase Coupling and the Cuprate Neutron Scattering Resonance
Wei-Cheng Lee, A. H. MacDonald
We examine the influence of coupling between particle-hole and particle-particle spin fluctuations on the inelastic neutron scattering resonance (INSR) in cuprate superconductors i…
Unconventional metamagnetic electron states in orbital band systems
Wei-cheng Lee, Congjun Wu
We extend the study of the Fermi surface instability of the Pomeranchuk type into systems with orbital band structures, which are common features in transition metal oxides. Band h…
Quantum Wells in Polar-Nonpolar Oxide Heterojunction Systems
C. -C Joseph Wang, Bhagawan Sahu, Hongki Min +2
We address the electronic structure of quantum wells in polar-nonpolar oxide heterojunction systems focusing on the case of non-polar BaVO wells surrounded by polar LaTiO b…
ARPES, Neutrons, and the High- Mechanism
Wei-Cheng Lee, A. H. MacDonald
Extensive ARPES and low-energy inelastic neutron scattering studies of cuprate superconductors can be successfully described using a weak-coupling theory in which quasiparticles on…
