Attosecond lighthouses from plasma mirrors

…, S Monchocé, H Vincenti, A Ricci, A Malvache… - Nature …, 2012 - nature.com
The nonlinear interaction of an intense femtosecond laser pulse with matter can lead to the
emission of a train of sub-laser-cycle—attosecond—bursts of short-wavelength radiation 1 , 2 …

[HTML][HTML] Light curves and colours of the ejecta from Dimorphos after the DART impact

…, LA Sgro, G Blaclard, A Borot, A Malvache… - Nature, 2023 - nature.com
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft struck
Dimorphos, a satellite of the asteroid 65803 Didymos 1 . Because it is a binary system, it is …

Awake hippocampal reactivations project onto orthogonal neuronal assemblies

A Malvache, S Reichinnek, V Villette, C Haimerl… - Science, 2016 - science.org
The chained activation of neuronal assemblies is thought to support major cognitive processes,
including memory. In the hippocampus, this is observed during population bursts often …

[PDF][PDF] Internally recurring hippocampal sequences as a population template of spatiotemporal information

V Villette, A Malvache, T Tressard, N Dupuy, R Cossart - Neuron, 2015 - cell.com
The hippocampus is essential for spatiotemporal cognition. Sequences of neuronal activation
provide a substrate for this fundamental function. At the behavioral timescale, these …

GABAergic inhibition shapes interictal dynamics in awake epileptic mice

SF Muldoon, V Villette, T Tressard, A Malvache… - Brain, 2015 - academic.oup.com
Epilepsy is characterized by recurrent seizures and brief, synchronous bursts called interictal
spikes that are present in-between seizures and observed as transient events in EEG …

Generation of 4.3 fs, 1 mJ laser pulses via compression of circularly polarized pulses in a gas-filled hollow-core fiber

X Chen, A Jullien, A Malvache, L Canova, A Borot… - Optics letters, 2009 - opg.optica.org
We report the generation of 4.3 fs, 1 mJ pulses at 1 kHz using a hollow-core fiber compressor
seeded with circularly polarized laser pulses. We observe up to 30% more energy …

Attosecond control of collective electron motion in plasmas

A Borot, A Malvache, X Chen, A Jullien, JP Geindre… - Nature Physics, 2012 - nature.com
Today, light fields of controlled and measured waveform can be used to guide electron
motion in atoms and molecules with attosecond precision. Here, we demonstrate attosecond …

Utilizing small telescopes operated by citizen scientists for transiting exoplanet follow-up

…, E Arbouch, M Kuchner, A Malvache - Publications of the …, 2020 - iopscience.iop.org
Due to the efforts by numerous ground-based surveys and NASA's Kepler and Transiting
Exoplanet Survey Satellite (TESS), there will be hundreds, if not thousands, of transiting …

Internal representation of hippocampal neuronal population spans a time-distance continuum

…, A Torcini, R Cossart, A Malvache - Proceedings of the …, 2019 - National Acad Sciences
The hippocampus plays a critical role in episodic memory: the sequential representation of
visited places and experienced events. This function is mirrored by hippocampal activity that …

Normotopic cortex is the major contributor to epilepsy in experimental double cortex

LF Petit, M Jalabert, E Buhler, A Malvache… - Annals of …, 2014 - Wiley Online Library
Objective Subcortical band heterotopia (SBH) is a cortical malformation formed when
neocortical neurons prematurely stop their migration in the white matter, forming a heterotopic …
