About carrier's self-trapping and dynamical Rashba splitting in the two-dimensional hybrid perovskite (BA)(MA)PbI
W. Qi, S. Ponzoni, G. Huitric +13
Time- and Angle-Resolved Photoelectron Spectroscopy (tr-ARPES) is employed to monitor photoexcited electrons in the two-dimensional hybrid perovskite (BA)(MA)PbI…
Wavefront shaping enhanced nano-optomechanics down to the quantum precision limit
Alexandros G. Tavernarakis, Rodrigo Gutiérrez-Cuevas, Loïc Rondin +3
We introduce wavefront shaping as a tool for optimizing the sensitivity in nano-optomechanical measurement schemes. We perform multimode output analysis of an optomechanical system…
Non-symmetrical vortex beam shaping in VECSEL laser arrays
Sopfy Karuseichyk, Ilan Audoin, Vishwa Pal +1
We propose and numerically test a novel concept for asymmetric vortex beam generation in a Degenerate Vertical External Cavity Surface Emitting Laser (DVECSEL). The method is based…
Ferroelectric texture of individual barium titanate nanocrystals
Athulya Muraleedharan, Kevin Co, Maxime Vallet +8
Ferroelectric materials display exotic polarization textures at the nanoscale that could be used to improve the energetic efficiency of electronic components. The vast majority of…
Creation and dynamics of spin fluctuations in a noisy magnetic field
J. Delpy, S. Liu, P. Neveu +4
We theoretically and numerically investigate the spin fluctuations induced in a thermal atomic ensemble by an external fluctuating uniaxial magnetic field, in the context of a stan…
Quantum Diamond Radio Frequency Signal Analyser based on Nitrogen-Vacancy centers
Simone Magaletti, Ludovic Mayer, Jean-François Roch +1
The fast development of radio-frequency (RF) technologies increases the need for compact, low consumption and broadband real-time RF spectral analyser. To overcome the electronic b…
Birefringence and dichroism effects in the spin noise spectra of a spin-1 system
S. Liu, P. Neveu, L. Hemmen +4
We perform spin noise spectroscopy experiments in metastable helium atoms at room temperature, with a probe light whose frequency is blue detuned from the D0 line. Both circular bi…
Sharp spectral variations of the ultrafast transient light extinction by bimetallic nanoparticles in the near-UV
Tadele Otomalo, Lorenzo Di Mario, Cyrille Hamon +6
Noble metal nanoparticles exhibit localized plasmon resonance modes that span the visible and near-infrared spectral ranges and have many applications. Modifying the size, shape, a…
Towards room-temperature superconductivity
Jacob Szeftel, Nicolas Sandeau, Michel Abou Ghantous +1
By taking advantage of a stability criterion established recently, the critical temperature is reckoned with help of the microscopic parameters, characterising the normal and…
Investigation of analog signal distortion introduced by a fiber phase sensitive amplifier
Debanuj Chatterjee, Yousra Bouasria, Weilin Xie +4
We numerically simulate the distortion of an analog signal carried in a microwave photonics link containing a phase sensitive amplifier (PSA), focusing mainly on amplitude modulati…
Optimization of laser dynamics for active stabilization of DF--VECSELs dedicated to cesium CPT clocks
Grégory Gredat, Hui Liu, Jérémie Cotxet +5
We report the implementation and performance of a double servo-loop for intensity and phase-difference active stabilization of a dual-frequency vertical external--cavity surface-em…
Investigation of the noise figure in degenerate dual-pump phase sensitive amplifier using a multi-wave model
Yousra Bouasria, Debanuj Chatterjee, Weilin Xie +4
A semi-classical 7-wave model is developed to investigate the noise performances of a degenerate dual-pump phase sensitive amplifier. This approach takes into account the transfer…
Highly anisotropic magnetic domain wall behavior in-plane magnetic films
Xiaochao Zhou, Nicolas Vernier, Guillaume Agnus +2
We have studied nucleation of magnetic domains and propagation of magnetic domain walls (DWs) induced by pulsed magnetic field in a ferromagnetic film with in-plane uniaxial anisot…
Dynamical control of square microlaser emission via symmetry classes
S. Bittner, A. Loirette-Pelous, C. Lafargue +5
A major objective in photonics is to tailor the emission properties of microcavities which is usually achieved with specific cavity shapes. Yet, the dynamical change of the emissio…
