Observation of the Eckhaus Instability in Whispering-Gallery Mode Resonators
Damià Gomila, Pedro Parra-Rivas, Pere Colet +6
The Eckhaus instability is a secondary instability of nonlinear spatiotemporal patterns in which high-wavenumber periodic solutions become unstable against small-wavenumber perturb…
Scaling of Memories and Crossover in Glassy Magnets
A. M. Samarakoon, M. Takahashi, D. Zhang +12
Glassiness is ubiquitous and diverse in characteristics in nature. Understanding their differences and classification remains a major scientific challenge. Here, we show that scali…
Cascaded Brillouin lasing in monolithic barium fluoride whispering gallery mode resonators
Guoping Lin, Souleymane Diallo, Khaldoun Saleh +4
We report the observation of stimulated Brillouin scattering and lasing at 1550~nm in barium fluoride (BaF) crystal. Brillouin lasing was achieved with ultra-high quality ()…
Barium fluoride whispering-gallery-mode disk-resonator with one billion quality-factor
Guoping Lin, Souleymane Diallo, Rémi Henriet +2
We demonstrate a monolithic optical whispering gallery mode resonator fabricated with barium fluoride (BaF) with an ultra-high quality () factor above at nm, a…
Diffusive Dynamics of Water inside Hydrophobic Carbon Micropores Studied by Neutron Spectroscopy and Molecular Dynamics Simulation
S. O. Diallo, L. Vlcek, E. Mamontov +4
When water molecules are confined to nanoscale spacings, such as in the nanometer size pores of activated carbon fiber (ACF), their freezing point gets suppressed down to very low…
Phonon-roton modes of liquid 4He beyond the roton in MCM-41
R. T. Azuah, S. O. Diallo, M. A. Adams +2
We present neutron scattering measurements of the phonon-roton (P-R) mode of superfluid 4He confined in 47 ÅMCM-41 at T = 0.5 K at wave vectors, Q, beyond the roton wave vector (Q_…
