Three-body interaction near a narrow two-body zero crossing
A. Pricoupenko, D. S. Petrov
We calculate the effective three-body force for bosons interacting with each other by a two-body potential tuned to a narrow zero crossing in any dimension. We use the standard two…
Stable p-wave resonant two-dimensional Fermi-Bose dimers
Betzalel Bazak, Dmitry S. Petrov
We consider two-dimensional weakly-bound heterospecies molecules formed in a Fermi-Bose mixture with attractive Fermi-Bose and repulsive Bose-Bose interactions. Bosonic exchanges l…
Dimer-dimer zero crossing and dilute dimerized liquid in a one-dimensional mixture
A. Pricoupenko, D. S. Petrov
We consider the system of dimers formed in a one-dimensional mass-balanced Bose-Bose mixture of species , with attractive interspecies and repulsive intras…
Two- and three-body problem with Floquet-driven zero-range interactions
A. G. Sykes, H. Landa, D. S. Petrov
We study the two-body scattering problem in the zero-range approximation with a sinusoidally driven scattering length and calculate the relation between the mean value and amplitud…
Five-Body Efimov Effect and Universal Pentamer in Fermionic Mixtures
Betzalel Bazak, Dmitry S. Petrov
We show that four heavy fermions interacting resonantly with a lighter atom (4+1 system) become Efimovian at mass ratio 13.279(2), which is smaller than the corresponding 2+1 and 3…
Anisotropic expansion of a thermal dipolar Bose gas
Yijun Tang, Andrew G. Sykes, Nathaniel Q. Burdick +3
We report on the anisotropic expansion of ultracold bosonic dysprosium gases at temperatures above quantum degeneracy and develop a quantitative theory to describe this behavior. T…
Universal three-body recombination and Efimov resonances in an ultracold Li-Cs mixture
J. Ulmanis, S. Häfner, R. Pires +4
We study Efimov resonances via three-body loss in an ultracold two-component gas of fermionic Li and bosonic Cs atoms close to a Feshbach resonance at 843~G, extending…
Three-body recombination in heteronuclear mixtures at finite temperature
D. S. Petrov, F. Werner
Within the universal zero-range theory, we compute the three-body recombination rate to deep molecular states for two identical bosons resonantly interacting with each other and wi…
Stable dilute supersolid of two-dimensional dipolar bosons
Zhen-Kai Lu, Yun Li, D. S. Petrov +1
We consider two-dimensional bosonic dipoles oriented perpendicularly to the plane. On top of the usual two-body contact and long-range dipolar interactions we add a contact three-b…
Elastic Multi-Body Interactions on a Lattice
D. S. Petrov
We show that by coupling two hyperfine states of an atom in an optical lattice one can independently control two-, three-, and four-body on-site interactions in a non-perturbative…
Three-Body Interacting Bosons in Free Space
D. S. Petrov
We propose a method of controlling two- and three-body interactions in an ultracold Bose gas in any dimension. The method requires us to have two coupled internal single-particle s…
The few-atom problem
D. S. Petrov
These lectures contain a theoretical introduction to the few-body problem with short-range resonant binary interactions. In the first part we discuss the effective range expansion…
Controlling integrability in a quasi-1D atom-dimer mixture
D. S. Petrov, V. Lebedev, J. T. M. Walraven
We analytically study the atom-dimer scattering problem in the near-integrable limit when the oscillator length l_0 of the transverse confinement is smaller than the dimer size, ~l…
Atom-dimer and dimer-dimer scattering in fermionic mixtures near a narrow Feshbach resonance
J. Levinsen, D. S. Petrov
We develop a diagrammatic approach for solving few-body problems in heteronuclear fermionic mixtures near a narrow interspecies Feshbach resonance. We calculate s-, p-, and d-wave…
Hydrodynamic behavior in expanding thermal clouds of Rb-87
I. Shvarchuck, Ch. Buggle, D. S. Petrov +4
We study hydrodynamic behavior in expanding thermal clouds of Rb-87 released from an elongated trap. At our highest densities the mean free path is smaller than the radial size of…
