Topologically driven Rabi-oscillating interference dislocation
Amir Rahmani, David Colas, Nina Voronova +3
Quantum vortices are the quantized version of classical vortices. Their center is a phase singularity or vortex core around which the flow of particles as a whole circulates and is…
Self-accelerating beam dynamics in the space fractional Schrödinger equation
David Colas
Self-accelerating beams are fascinating solutions of the Schrödinger equation. Thanks to their particular phase engineering, they can accelerate without the need of external potent…
What is a quantum shock wave?
S. A. Simmons, F. A. Bayocboc, J. C. Pillay +3
Shock waves are examples of the far-from-equilibrium behaviour of matter; they are ubiquitous in nature, yet the underlying microscopic mechanisms behind their formation are not we…
Finite-energy accelerating beam dynamics in wavelet-based representations
David Colas, Fabrice P. Laussy, Matthew J. Davis
Accelerating beams are wave packets which appear to spontaneously accelerate without external potentials or applied forces. Since their first physical realisation in the form of Ai…
Formation of nonlinear X-waves in condensed matter systems
David Colas, Fabrice P. Laussy, Matthew J. Davis
X-waves are an example of a localized wave packet solution of the homogeneous wave equation, and can potentially arise in any area of physics relating to wave phenomena, such as ac…
Negative-mass effects in spin-orbit coupled Bose-Einstein condensates
David Colas, Fabrice P. Laussy, Matthew J. Davis
Negative effective masses can be realised by engineering the dispersion relation in a variety of quantum systems. A recent experiment with spin-orbit coupled Bose-Einstein condensa…
