Tracking complex singularities of fluids on log-lattices

Quentin Pikeroen, Amaury Barral, Guillaume Costa +3

In 1981, Frisch and Morf [1] postulated the existence of complex singularities in solutions of Navier-Stokes equations. Present progress on this conjecture is hindered by the compu…

Bose-Einstein condensation in systems with flux equilibrium

Victor S. L'vov, Anna Pomyalov, Sergey V. Nazarenko +4

We consider flux equilibrium in dissipative nonlinear wave systems subject to external energy pumping. In such systems, the elementary excitations, or quasiparticles, can create a…

Spontaneously sliding multipole spin density waves in cold atoms

G. Labeyrie, J. G. M. Walker, G. R. M. Robb +2

We report on the observation of spontaneously drifting coupled spin and quadrupolar density waves in the ground state of laser driven Rubidium atoms. These laser-cooled atomic ense…

Bound states in the continuum induced via local symmetries in complex structures

Cheng-Zhen Wang, Ulrich Kuhl, Adin Dowling +2

Bound states in the continuum (BICs) defy conventional wisdom that assumes a spectral separation between propagating waves, that carry energy away, and spatially localized waves co…

Higgs oscillations in a unitary Fermi superfluid

P. Dyke, S. Musolino, H. Kurkjian +7

Symmetry-breaking phase transitions are central to our understanding of states of matter. When a continuous symmetry is spontaneously broken, new excitations appear that are tied t…

Determination of the moments of the proton charge density: is there a proton radius puzzle?

M. Atoui, M. B. Barbaro, M. Hoballah +6

The charge radius of the proton can be determined using two different kinds of experiments: the spectroscopy technique, measuring the hyperfine structure of hydrogen atoms, and the…

Rayleigh-Jeans thermalization vs beam cleaning in multimode optical fibers

Kilian Baudin, Josselin Garnier, Adrien Fusaro +4

Classical nonlinear waves exhibit, as a general rule, an irreversible process of thermalization toward the Rayleigh-Jeans equilibrium distribution. On the other hand, several recen…
