Bose-Einstein condensate in a shell: nonlinear modes and symmetry breaking
Alexander Wolf, Vladimir V. Konotop, Maxim A. Efremov
The state of a quantum particle confined to a spherical surface is commonly described using spherical harmonics, which play a crucial role in solving many scientific problems featu…
Optimal Diffractive Focusing of Vortex Beams
Roohollah Ghobadi, Carrie Rodriguez, Lukas Scarfe +2
We formulate diffractive ring focusing of paraxial beams carrying orbital angular momentum (OAM) through a finite circular aperture as a variational optimization problem. For a fix…
Observation of Phase Space Dynamics of Inverted Harmonic Oscillator
Georgi Gary Rozenman, Maxim A. Efremov, Wolfgang P. Schleich +2
We have experimentally realized a parabolic potential barrier for surface gravity water waves. The analogy between the resulting wave equation and the Schrodinger equation for the…
Signatures of the circular Unruh effect in electric and magnetic dipole transitions of multilevel atoms
Gregor Janson, Fabio Di Pumpo, Lorenz Thoma +1
The circular Unruh effect is the excitation of a detector moving along a planar circular trajectory within an electromagnetic vacuum. We demonstrate that the magnetic dipole transi…
Confinement-Induced Resonances in Spherical Shell Traps
C. Moritz Carmesin, Maxim A. Efremov
The energy spectrum and corresponding wave functions of two bosonic particles confined in a spherically symmetric shell trap and interacting via a three-dimensional zero-range pote…
