Universal formula for the mean first passage time in planar domains
Denis S. Grebenkov
We derive a general exact formula for the mean first passage time (MFPT) from a fixed point inside a planar domain to an escape region on its boundary. The underlying mixed Dirichl…
The escape problem for mortal walkers
D. S. Grebenkov, J. -F. Rupprecht
We introduce and investigate the escape problem for random walkers that may eventually die, decay, bleach, or lose activity during their diffusion towards an escape or reactive reg…
Spin and recombination dynamics of excitons and free electrons in p-type GaAs : effect of carrier density
F. Cadiz, D. Lagarde, P. Renucci +5
Carrier and spin recombination are investigated in p-type GaAs of acceptor concentration NA = 1.5 x 10^(17) cm^(-3) using time-resolved photoluminescence spectroscopy at 15 K. At l…
Polarizers, optical bridges and Sagnac interferometers for nanoradian polarization rotation measurements
Alistair Rowe, Indira Zhaksylykova, Guillaume Dilasser +2
The ability to measure nanoradian polarization rotations, , in the photon shot noise limit is investigated for partially crossed polarizers (PCP), a static Sagnac interferomet…
On spectral properties of the Bloch-Torrey operator in two dimensions
D. S. Grebenkov, B. Helffer
We investigate a two-dimensional Schrödinger operator, , with a purely complex potential . A rigorous definition of this non-selfadjoint operator is provided f…
On-chip generation of heralded photon-number states
Panagiotis Vergyris, Thomas Meany, Tommaso Lunghi +5
Beyond the use of genuine monolithic integrated optical platforms, we report here a hybrid strategy enabling on-chip generation of configurable heralded two-photon states. More spe…
One single static measurement predicts wave localization in complex structures
Gautier Lefebvre, Alexane Gondel, Marc Dubois +9
A recent theoretical breakthrough has brought a new tool, called \emph{localization landscape}, to predict the localization regions of vibration modes in complex or disordered syst…
Lattice Boltzmann simulations of 3D crystal growth: Numerical schemes for a phase-field model with anti-trapping current
Alain Cartalade, Amina Younsi, Mathis Plapp
A lattice-Boltzmann (LB) scheme, based on the Bhatnagar-Gross-Krook (BGK) collision rules is developed for a phase-field model of alloy solidification in order to simulate the grow…
