Orbital-assisted metal-insulator transition in VO
M. W. Haverkort, Z. Hu, A. Tanaka +9
We found direct experimental evidence for an orbital switching in the V 3d states across the metal-insulator transition in VO. We have used soft-x-ray absorption spectroscopy…

Analytical approach to the quantum-phase transition in the one-dimensional spinless Holstein model
S. Sykora, A. Huebsch, K. W. Becker
We study the one-dimensional Holstein model of spinless fermions interacting with dispersion-less phonons by using a recently developed projector-based renormalization method (PRM)…
