Anyonic Haldane Insulator in One Dimension

2017-03-23T10:00:00-04:00

Author(s): Florian Lange, Satoshi Ejima, and Holger Fehske
We demonstrate numerically the existence of a nontrivial topological Haldane phase for the one-dimensional extended (U−V) Hubbard model with a mean density of one particle per site, not only for bosons but also for anyons, despite a broken reflection parity symmetry. The Haldane insulator, surrounde…

Symmetry for Flavor-Kinematics Duality from an Action

2017-03-23T10:00:00-04:00

Author(s): Clifford Cheung and Chia-Hsien Shen
We propose a new representation of the nonlinear sigma model that exhibits a manifest duality between flavor and kinematics. The fields couple exclusively through cubic Feynman vertices which define the structure constants of an underlying kinematic algebra. The action is invariant under a combinati…

Author(s): J. Goetz, S. Pogorzalek, F. Deppe, K. G. Fedorov, P. Eder, M. Fischer, F. Wulschner, E. Xie, A. Marx, and R. Gross
In experiments with superconducting quantum circuits, characterizing the photon statistics of propagating microwave fields is a fundamental task. We quantify the n^{2}+n photon number variance of thermal microwave photons emitted from a blackbody radiator for mean photon numbers, 0.05≲n≲1.5. We prob…
