On particle number fluctuations in an interacting pion gas with dynamically fixed number of particles

On the fixed number of graphs

‎A set of vertices $S$ of a graph $G$ is called a fixing set of $G$‎, ‎if only the trivial automorphism of $G$ fixes every vertex in $S$‎. ‎The fixing number of a graph is the smallest cardinality of a fixing‎ ‎set‎. ‎The fixed number of a graph $G$ is the minimum $k$‎, ‎such that ‎every $k$-set of vertices of $G$ is a fixing set of $G$‎. ‎A graph $G$‎ ‎is called a $k$-fixed graph‎, ‎if its fix...

1 Time - Resolved Measurements of Thermodynamic Fluctuations of the Particle Number in a Dilute Fermi Gas

We report on time-resolved measurements of thermodynamic fluctuations in the number of particles in a dilute Fermi gas. The gas is comprised of thermal quasiparticles, confined in a superconducting Al box by large-gap Ta leads. The average number of quasiparticles is about 10 5. This number fluctuates due to the quasiparticle generation and recombination processes. The number is measured from t...

Time-resolved measurements of thermodynamic fluctuations of the particle number in a nondegenerate Fermi gas.

We report on time-resolved measurements of thermodynamic fluctuations in the number of particles in a nondegenerate Fermi gas. The gas is comprised of thermal quasiparticles, confined in a superconducting Al box by large-gap Ta leads. The average number of quasiparticles is about 10(5). This number fluctuates due to quasiparticle generation and recombination. The number is measured from the tun...

Multi-Particle Anderson Localisation: Induction on the Number of Particles

This paper is a follow-up of our recent papers [CS08] and [CS09] covering the two-particle Anderson model. Here we establish the phenomenon of Anderson localisation for a quantum N -particle system on a lattice Z with short-range interaction and in presence of an IID external potential with sufficiently regular marginal cumulative distribution function (CDF). Our main method is an adaptation of...
