Quantum flutter of supersonic particles in one-dimensional quantum liquids
Fast particles propagating through a classical medium give rise to shock waves. Calculations now uncover the surprising behaviour of particles in one-dimensional quantum fluids: a fast particle will…

A new instance-based learning algorithm called the Boundary Forest algorithm, that can be used for supervised and unsupervised learning, which can be shown data points one at a time and updates itself incrementally, hence it is nat- urally online.
Quantum flutter: signatures and robustness.
The results indicate that quantum flutter exists away from integrability and provide parameter regions in which it could be observed in experiments with ultracold atoms using currently available technology.
Trimers, molecules, and polarons in mass-imbalanced atomic Fermi gases.
It is found that the presence of a Fermi sea enhances the stability of the p-wave trimer, which can be viewed as a Fulde-Ferrell-Larkin-Ovchinnikov molecule that has bound an additional majority atom.
Enlarging and cooling the Néel state in an optical lattice
We propose an experimental scheme to favor both the realization and the detection of the Neel state in a two-component gas of ultracold fermions in a three-dimensional simple-cubic optical lattice.…
Proximal Operators for Multi-Agent Path Planning
New operators to deal with agents moving in arbitrary dimensions that are faster to compute than their 2D predecessors are introduced and landmarks, space-time positions that are automatically assigned to the set of agents under different optimality criteria are introduced.
Phase separation and collapse in Bose-Fermi mixtures with a Feshbach resonance
We consider a mixture of single-component bosonic and fermionic atoms with an interspecies interaction that is varied using a Feshbach resonance. By performing a mean-field analysis of a two-channel…
The breaking of quantum double symmetries by defect condensation
Accessing the Néel phase of ultracold fermionic atoms in a simple-cubic optical lattice
For a simple-cubic optical lattice with lattice spacing d, occupied by two species of fermionic atoms of mass m that interact repulsively, we ask what conditions maximize the Neel temperature in the…
Experimental signatures of phase interference and subfemtosecond time dynamics on the incident energy axis of resonant inelastic x-ray scattering
Core hole resonance is used in X-ray spectroscopy to incisively probe the local electronic states of many-body systems. Here, resonant inelastic X-ray scattering (RIXS) is studied as a function of…
