Small Clusters of He Atoms in Finite-Cutoff Effective Field Theory
Betzalel Bazak
Small clusters of He atoms are benchmark systems for universal few-body physics near the unitary limit. We study these systems using a finite-cutoff effective field theory cali…
Few-body bound states of two-dimensional bosons
G. Guijarro, G. E. Astrakharchik, J. Boronat +2
We study clusters of the type AB with in a two-dimensional mixture of A and B bosons, with attractive AB and equally repulsive AA and BB interactions. In or…
Universal Short Range Correlations in Bosonic Helium Clusters
Betzalel Bazak, Manuel Valiente, Nir Barnea
Short-range correlations in bosonic Helium clusters, composed of He atoms, are studied utilizing the generalized contact formalism. The emergence of universal -body short ra…
Efimov physics beyond three particles
Betzalel Bazak
Efimov physics originally refers to a system of three particles. Here we review recent theoretical progress seeking for manifestations of Efimov physics in systems composed of more…
Four-Body Scale in Universal Few-Boson Systems
Betzalel Bazak, Johannes Kirscher, Sebastian König +3
The role of an intrinsic four-body scale in universal few-boson systems is the subject of active debate. We study these systems within the framework of effective field theory. For…
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…
