Multistable binary decision making on networks
Andrew Lucas, Ching Hua Lee
We propose a simple model for a binary decision making process on a graph, motivated by modeling social decision making with cooperative individuals. The model is similar to a rand…
From d-wave to s-wave pairing in the iron-pnictide superconductor (Ba,K)Fe2As2
J. -Ph. Reid, A. Juneau-Fecteau, R. T. Gordon +18
The nature of the pairing state in iron-based superconductors is the subject of much debate. Here we argue that in one material, the stoichiometric iron pnictide KFe2As2, there is…
Pseudopotential Formalism for Fractional Chern Insulators
Ching Hua Lee, Ronny Thomale, Xiao-Liang Qi
Recently, generalizations of fractional quantum Hall (FQH) states known as fractional quantum anomalous Hall or, equivalently, fractional Chern insulators states have been realized…
Universal heat conduction in the iron-arsenide superconductor KFe2As2 : Evidence of a d-wave state
J. -Ph. Reid, M. A. Tanatar, A. Juneau-Fecteau +12
The thermal conductivity of the iron-arsenide superconductor KFe2As2 was measured down to 50 mK for a heat current parallel and perpendicular to the tetragonal c-axis. A residual l…
