Quantum gas-enabled direct mapping of active current density in percolating networks of nanowires
J. Fekete, P. Joshi, T. J. Barrett +6
Electrically percolating nanowire networks are amongst the most promising candidates for next-generation transparent electrodes. Scientific interest in these materials stems from t…
Using graphene conductors to enhance the functionality of atom-chips
K. Wongcharoenbhorn, R. Crawford, N. Welch +6
We show that the performance and functionality of atom-chips can be transformed by using graphene-based van der Waals heterostructures to overcome present limitations on the lifeti…
Surface band characters of Weyl semimetal candidate material MoTe revealed by one-step ARPES theory
Ryota Ono, Alberto Marmodoro, Jakub Schusser +7
The layered 2D-material MoTe in the T crystal phase is a semimetal which has theoretically been predicted to possess topologically non-trivial bands corresponding to Weyl f…
Many-Body Atomic Speed Sensor in Lattices
Salvatore Marco Giampaolo, Andrea Trombettoni, Peter Krüger +1
We study the properties of transmissivity of a beam of atoms traversing an optical lattices loaded with ultracold atoms. The transmission properties as function of the energy of th…
Performing Hong-Ou-Mandel-type Numerical Experiments with Repulsive Condensates: The case of Dark and Dark-bright Solitons
Zhi-Yuan Sun, Panayotis G. Kevrekidis, Peter Krüger
The Hong-Ou-Mandel experiment leads indistinguishable photons simultaneously reaching a 50:50 beam splitter to emerge on the same port through two-photon interference. Motivated by…

We investigate the flow of a one-dimensional nonlinear Schrodinger model with periodic boundary conditions past an obstacle, motivated by recent experiments with Bose--Einstein con…
Scattering of matter-waves in spatially inhomogeneous environments
F. Tsitoura, P. Krüger, P. G. Kevrekidis +1
We study scattering of quasi one-dimensional matter-waves at an interface of two spatial domains, one with repulsive and one with attractive interatomic interactions. It is shown t…
A Mean-Field Analogue of the Hong-Ou-Mandel Experiment With Bright Solitons
Zhi-Yuan Sun, Panayotis G. Kevrekidis, Peter Krüger
In the present work, we theoretically propose and numerically illustrate a mean-field analogue of the Hong-Ou-Mandel experiment with bright solitons. More specifically, we scatter…
One-dimensional transport of bosons between weakly linked reservoirs
D. P. Simpson, D. M. Gangardt, I. V. Lerner +1
We study a flow of ultracold bosonic atoms through a one-dimensional channel that connects two macroscopic three-dimensional reservoirs of Bose-condensed atoms via weak links imple…
First-principles calculations of spin and angle-resolved resonant photoemission spectra of Cr(110) surfaces at the 2 - 3 resonance
F. Da Pieve, P. Krüger
A first principles approach for spin and angle resolved resonant photoemission is developed within multiple scattering theory and applied to a Cr(110) surface at the 2-3 reso…
