Photoemission evidence for crossover from Peierls-like to Mott-like transition in highly strained VO
J. Laverock, A. R. H. Preston, D. Newby +8
We present a spectroscopic study that reveals that the metal-insulator transition of strained VO thin films may be driven towards a purely electronic transition, which does not…
Networks of quantum wire junctions: a system with quantized integer Hall resistance without vanishing longitudinal resistivity
Jaime Medina, Dmitry Green, Claudio Chamon
We consider a honeycomb network built of quantum wires, with each node of the network having a Y-junction of three wires with a ring through which flux can be inserted. The junctio…
Correlated valence-bond states
Yu-Cheng Lin, Ying Tang, Jie Lou +1
We study generalizations of the singlet-sector amplitude-product (AP) states in the valence-bond basis of S=1/2 quantum spin systems. In the standard AP states, the weight of a til…
Magnetic translation algebra with or without magnetic field in the continuum or on arbitrary Bravais lattices in any dimension
Claudio Chamon, Christopher Mudry
The magnetic translation algebra plays an important role in the quantum Hall effect. Murthy and Shankar, arXiv:1207.2133, have shown how to realize this algebra using fermionic bil…
Enhancing the stability of a fractional Chern insulator against competing phases
Adolfo G. Grushin, Titus Neupert, Claudio Chamon +1
We construct a two-band lattice model whose bands can carry the Chern numbers C=0,pm1,pm2. By means of numerical exact diagonalization, we show that the most favorable situation th…
Elementary formula for the Hall conductivity of interacting systems
Titus Neupert, Luiz Santos, Claudio Chamon +1
A formula for the Hall conductivity of interacting electrons is given under the assumption that the ground state manifold is N_gs-fold degenerate and discrete translation symmetry…
Junctions of multiple quantum wires with different Luttinger parameters
Chang-Yu Hou, Armin Rahmani, Adrian E. Feiguin +1
Within the framework of boundary conformal field theory, we evaluate the conductance of stable fixed points of junctions of two and three quantum wires with different Luttinger par…
Bridging lattice-scale physics and continuum field theory with quantum Monte Carlo simulations
Ribhu K. Kaul, Roger G. Melko, Anders W. Sandvik
We discuss designer Hamiltonians---lattice models tailored to be free from sign problems ("de-signed") when simulated with quantum Monte Carlo methods but which still host complex…
Strain dependence of bonding and hybridization across the metal-insulator transition of VO2
J. Laverock, L. F. J. Piper, A. R. H. Preston +8
Soft x-ray spectroscopy is used to investigate the strain dependence of the metal-insulator transition of VO2. Changes in the strength of the V 3d - O 2p hybridization are observed…
Antiferromagnetic order in systems with doublet ground states
Sambuddha Sanyal, Argha Banerjee, Kedar Damle +1
We use projector Quantum Monte-Carlo methods to study the doublet ground states of two dimensional antiferromagnets on a square lattice with…
Noncommutative geometry for three-dimensional topological insulators
Titus Neupert, Luiz Santos, Shinsei Ryu +2
We generalize the noncommutative relations obeyed by the guiding centers in the two-dimensional quantum Hall effect to those obeyed by the projected position operators in three-dim…
Finite-size scaling and boundary effects in two-dimensional valence-bond-solids
Anders W. Sandvik
Various lattice geometries and boundaries are used to investigate valence-bond-solid (VBS) ordering in the ground state of an S=1/2 square-lattice quantum spin model---the J-Q mode…
