Exotic roton excitations in quadrupolar Bose-Einstein condensates
M. Lahrz, Mikhail Lemeshko, L. Mathey
We investigate the occurrence of rotons in a quadrupolar Bose-Einstein condensate confined to two dimensions. Depending on the particle density, the ratio of the contact and quadru…
Probing chirality fluctuations in molecules by nonlinear optical spectroscopy
N. Mann, P. Nalbach, S. Mukamel +1
Symmetry breaking caused by geometric fluctuations can enable processes that are otherwise forbidden. An example is a perylene bisimide dyad whose dipole moments are perpendicular…
Quantum Speed Limit and Optimal Control of Many-Boson Dynamics
Ioannis Brouzos, Alexej I. Streltsov, Antonio Negretti +4
We extend the concept of quantum speed limit -- the minimal time needed to perform a driven evolution -- to complex interacting many-body systems. We investigate a prototypical man…
Stability and Tunneling Dynamics of a Dark-Bright Soliton Pair in a Harmonic Trap
E. T. Karamatskos, J. Stockhofe, P. G. Kevrekidis +1
We consider a binary repulsive Bose-Einstein condensate in a harmonic trap in one spatial dimension and investigate particular solutions consisting of two dark-bright (DB) solitons…
Many-body processes in black and grey matter-wave solitons
Sven Krönke, Peter Schmelcher
We perform a comparative beyond mean-field study of black and grey solitonic excitations in a finite ensemble of ultracold bosons confined to a one-dimensional box. An optimized de…
Terahertz-driven linear electron acceleration
Emilio Alessandro Nanni, Wenqian Ronny Huang, Kyung-Han Hong +5
The cost, size and availability of electron accelerators is dominated by the achievable accelerating gradient. Conventional high-brightness radio-frequency (RF) accelerating struct…
