Quenches across the self-organization transition in multimode cavities
Tim Keller, Valentin Torggler, Simon B. Jäger +3
A cold dilute atomic gas in an optical resonator can be radiatively cooled by coherent scattering processes when the driving laser frequency is tuned close but below the cavity res…
Correlation between peak-height modulation and phase-lapses in transport through quantum dots
Rodolfo A. Jalabert, Rafael A. Molina, Guillaume Weick +1
We show that two intriguing features of mesoscopic transport, namely the modulation of Coulomb blockade peak-heights and the transmission phase-lapses occurring between subsequent…
Retardation effects on the dispersion and propagation of plasmons in metallic nanoparticle chains
Charles A. Downing, Eros Mariani, Guillaume Weick
We consider a chain of regularly-spaced spherical metallic nanoparticles, where each particle supports three degenerate localized surface plasmons. Due to the dipolar interaction b…
Ultrafast hot-electron induced quenching of Tb4f magnetic order
T. Ferte, N. Bergeard, G. Malinowski +5
We have investigated ultrafast quenching of the Tb4f magnetic order in Co74Tb26 alloys, induced by femtosecond hot-electrons pulses. The hot-electron pulses were produced in specif…
Element-resolved ultrafast demagnetization rates in ferrimagnetic CoDy
T. Ferte, N. Bergeard, L. Le Guyader +7
Femtosecond laser induced ultrafast magnetization dynamics have been studied in multisublattice CoxDy1-x alloys. By performing element and time-resolved X-ray spectroscopy, we dist…

Guillaume Froehlicher, Etienne Lorchat, Olivia Zill +2
We report a comparative study of rigid layer Raman-active modes in -layer transition metal dichalcogenides. Trigonal prismatic (2Hc, such as MoSe, MoTe, WS, WSe)…
Localization of massless Dirac particles via spatial modulations of the Fermi velocity
C. A. Downing, M. E. Portnoi
The electrons found in Dirac materials are notorious for being difficult to manipulate due to the Klein phenomenon and absence of backscattering. Here we investigate how spatial mo…
