费米子和玻色子的广义干涉

Generalized Interference of Fermions and Bosons

Dylan Spivak, Murphy Yuezhen Niu, Barry C. Sanders, Hubert de Guise

摘要:

利用表象理论的工具,我们推导出干涉实验中部分可分辨粒子的符合率的表达式。我们的表达式对玻色子或费米子都有效,对任何数量的粒子都有效。在$n$粒子的实验中,我们导出的表达式包含整数$n$的每个分区的一项; Gamas定理用于确定这些项中的哪些项自动为零,基于粒子之间的成对可扩展性水平。大多数采样方案(如玻色子采样)仅限于完全不可区分的粒子;我们的工作有助于理解允许任意水平可分辨性的系统。作为我们工作的一个应用,我们引入了一个部分可区分费米子的采样方案,我们称之为广义费米子采样。

英文摘要:

Using tools from representation theory, we derive expressions for the coincidence rate of partially-distinguishable particles in an interferometry experiment. Our expressions are valid for either bosons or fermions, and for any number of particles. In an experiment with $n$ particles the expressions we derive contain a term for each partition of the integer $n$; Gamas's theorem is used to determine which of these terms are automatically zero based on the pairwise level of distinguishability between particles. Most sampling schemes (such as Boson Sampling) are limited to completely indistinguishable particles; our work aids in the understanding of systems where an arbitrary level of distinguishability is permitted. As an application of our work we introduce a sampling scheme with partially-distinguishable fermions, which we call Generalized Fermion Sampling.
