Clusters in Separated Tubes of Tilted Dipoles
Jeremy R. Armstrong, Aksel S. Jensen, Artem G. Volosniev +1
A few-body cluster is a building block of a many-body system in a gas phase provided the temperature at most is of the order of the binding energy of this cluster. Here we illustra…
Partially coherent quantum degenerate electron matter waves
Sam Keramati, Eric R. Jones, Jeremy Armstrong +1
The use of electron beams is ubiquitous; electron microscopy, scanning tunneling microscopy, electron lithography, and electron diffractometry all use well-collimated and focused b…
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…
Analytic solutions of topologically disjoint systems
J. R. Armstrong, A. G. Volosniev, D. V. Fedorov +2
We describe a procedure to solve an up to problem where the particles are separated topologically in groups with at most two particles in each. Arbitrary interactions are…
Bound states of Dipolar Bosons in One-dimensional Systems
A. G. Volosniev, J. R. Armstrong, D. V. Fedorov +3
We consider one-dimensional tubes containing bosonic polar molecules. The long-range dipole-dipole interactions act both within a single tube and between different tubes. We consid…
Virial expansion coefficients in the harmonic approximation
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
The virial expansion method is applied within a harmonic approximation to an interacting N-body system of identical fermions. We compute the canonical partition functions for two a…
Many-particle Systems in One Dimension in the Harmonic Approximation
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
We consider energetics and structural properties of a many particle system in one dimension with pairwise contact interactions confined in a parabolic external potential. To render…
Quantum Statistics and Thermodynamics in the Harmonic Approximation
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
We describe a method to compute thermodynamic quantities in the harmonic approximation for identical bosons and fermions in an external confining field. We use the canonical partit…
Thermodynamics of Dipolar Chain Systems
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
The thermodynamics of a quantum system of layers containing perpendicularly oriented dipolar molecules is studied within an oscillator approximation for both bosonic and fermionic…
Bound Chains of Tilted Dipoles in Layered Systems
A. G. Volosniev, J. R. Armstrong, D. V. Fedorov +2
Ultracold polar molecules in multilayered systems have been experimentally realized very recently. While experiments study these systems almost exclusively through their chemical r…
Layers of Cold Dipolar Molecules in the Harmonic Approximation
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
We consider the N-body problem in a layered geometry containing cold polar molecules with dipole moments that are polarized perpendicular to the layers. A harmonic approximation is…
Dimers, Effective Interactions, and Pauli Blocking Effects in a Bilayer of Cold Fermionic Polar Molecules
N. T. Zinner, J. R. Armstrong, A. G. Volosniev +2
We consider a bilayer setup with two parallel planes of cold fermionic polar molecules when the dipole moments are oriented perpendicular to the planes. The binding energy of two-b…
Weakly bound states of polar molecules in bilayers
D. V. Fedorov, J. R. Armstrong, N. T. Zinner +1
We investigate a system of two polarized molecules in a layered trap. The molecules reside in adjacent layers and interact purely via the dipole-dipole interaction. We determine th…
Analytic Harmonic Approach to the N-body problem
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
We consider an analytic way to make the interacting N-body problem tractable by using harmonic oscillators in place of the relevant two-body interactions. The two body terms of the…
Bound States and Universality in Layers of Cold Polar Molecules
J. R. Armstrong, N. T. Zinner, D. V. Fedorov +1
The recent experimental realization of cold polar molecules in the rotational and vibrational ground state opens the door to the study of a wealth of phenomena involving long-range…
