Impact of dark states on the stationary properties of quantum particles with off-centered interactions in one dimension
G. Bougas, N. L. Harshman, P. Schmelcher
We present a generalization of the two-body contact interaction for non-relativistic particles trapped in one dimension. The particles interact only when they are a distance c apar…
Topological Exchange Statistics in One Dimension
N. L. Harshman, A. C. Knapp
The standard topological approach to indistinguishable particles formulates exchange statistics by using the fundamental group to analyze the connectedness of the configuration spa…
Probing the edge between integrability and quantum chaos in interacting few-atom systems
Thomás Fogarty, Miguel Ángel García-March, Lea F. Santos +1
Interacting quantum systems in the chaotic domain are at the core of various ongoing studies of many-body physics, ranging from the scrambling of quantum information to the onset o…
Quantum Chirikov criterion: Two particles in a box as a toy model for a quantum gas
Dmitry Yampolsky, N. L. Harshman, Vanja Dunjko +2
We consider a toy model for emergence of chaos in a quantum many-body short-range-interacting system: two one-dimensional hard-core particles in a box, with a small mass defect as…
Graded-index optical fiber emulator of an interacting three-atom system: illumination control of particle statistics and classical non-separability
M. A. Garcia-March, N. L. Harshman, H. da Silva +4
We show that a system of three trapped ultracold and strongly interacting atoms in one-dimension can be emulated using an optical fiber with a graded-index profile and thin metalli…
A Solvable Model for Decoupling of Interacting Clusters
Artem G. Volosniev, Aksel S. Jensen, Nathan L. Harshman +2
We consider M clusters of interacting particles, whose in-group interactions are arbitrary, and inter-group interactions are approximated by oscillator potentials. We show that the…
