Topology of tiling spaces
TL;DR: The notion of tilings spaces and inverse limits was introduced in this article, where the authors propose a relaxation of the rules for tilings without finite local complexity, based on the notion of inverse limits.
Journal ArticleDOI
Chern Numbers, Quaternions, and Berry's Phases in Fermi Systems
TL;DR: On determine les nombres de Chern, les quaternions, and les phases of Berry dans des systemes de Fermi as discussed by the authors. But le nombre de Chern is not assez concret.
Journal ArticleDOI
Optimal quantum pumps.
TL;DR: A general lower bound on dissipation in a quantum channel is proved and optimal pumps are defined as those that saturate the bound and are given a geometric characterization of optimal pumps and shown to be noiseless and transport integral charge in a cycle.
Journal ArticleDOI
Geometry, statistics, and asymptotics of quantum pumps
TL;DR: In this article, a pedestrian interpretation of a formula of Buttiker et al. relating the adiabatically pumped current to the S matrix and its (time) derivatives is given. Buttiker et.
Journal ArticleDOI
Topological Invariants in Fermi Systems with Time-Reversal Invariance
TL;DR: Topological invariants for Fermi systems that have time-reversal invariance are discussed, including the connection that governs the adiabatic evolution coincides with the symmetric SU(2) Yang-Mills instanton.
