Random Field Driven Spatial Complexity at the Mott Transition in VO2
Shuo Liu, B. Phillabaum, E. W. Carlson +4
We report the first application of critical cluster techniques to the Mott metal-insulator transition in vanadium dioxide. We show that the geometric properties of the metallic and…
Tunable nano Peltier cooling device from geometric effects using a single graphene nanoribbon
Wan-Ju Li, Dao-Xin Yao, E. W. Carlson
Based on the phenomenon of curvature-induced doping in graphene we propose a class of Peltier cooling devices, produced by geometrical effects, without gating. We show how a graphe…
Quantum phase transitions in disordered dimerized quantum spin models and the Harris criterion
Dao-Xin Yao, Jonas Gustafsson, E. W. Carlson +1
We use quantum Monte Carlo simulations to study effects of disorder on the quantum phase transition occurring versus the ratio g=J/J' in square-lattice dimerized S=1/2 Heisenberg a…
Noise Predictions for STM in Systems with Local Electron Nematic Order
Y. L. Loh, E. W. Carlson, K. A. Dahmen
We propose that thermal noise in local stripe orientation should be readily detectable via STM on systems in which local stripe orientations are strongly affected by quenched disor…
Magnetic Excitations of Undoped Iron Oxypnictides
Dao-Xin Yao, E. W. Carlson
We study the magnetic excitations of undoped iron oxypnictides using a three-dimensional Heisenberg model with single-ion anisotropy. Analytic forms of the spin wave dispersion, ve…
Low energy spin waves and magnetic interactions in SrFeAs
Jun Zhao, Dao-Xin Yao, Shiliang Li +12
We report inelastic neutron scattering studies of magnetic excitations in antiferromagnetically ordered SrFeAs ( K), the parent compound of the FeAs-based su…
