A unifying approach to first-passage time distributions in diffusing diffusivity and switching diffusion models
D. S. Grebenkov
We propose a unifying theoretical framework for the analysis of first-passage time distributions in two important classes of stochastic processes in which the diffusivity of a part…
Towards a full quantitative description of single-molecule reaction kinetics in biological cells
Denis S. Grebenkov, Ralf Metzler, Gleb Oshanin
The first-passage time (FPT), i.e., the moment when a stochastic process reaches a given threshold value for the first time, is a fundamental mathematical concept with immediate ap…
Structural and temporal heterogeneities on networks
Liubov Tupikina, Denis S. Grebenkov
A heterogeneous continuous time random walk is an analytical formalism for studying and modeling diffusion processes in heterogeneous structures on microscopic and macroscopic scal…
Probing surface-to-volume ratio of an anisotropic medium by diffusion {NMR} with general gradient encoding
Nicolas Moutal, Ivan I. Maximov, Denis S. Grebenkov
Since the seminal paper by Mitra et al., diffusion MR has been widely used in order to estimate surface-to-volume ratios. In the present work we generalize Mitra's formula for arbi…
Mechanical stress dependence of the Fermi level pinning on an oxidized silicon surface
H. Li, L. Martinelli, F. Cadiz +4
A combination of micro-Raman spectroscopy and micro-XPS (X-ray photo-electron spectroscopy) mapping on statically deflected p-type silicon cantilevers is used to study the mechanic…
Optimal parameters for anomalous diffusion exponent estimation from noisy data
Yann Lanoiselée, Denis S. Grebenkov, Grzegorz Sikora +2
The most common way of estimating the anomalous diffusion exponent from single-particle trajectories consists in a linear fitting of the dependence of the time averaged mean square…
Emergence of correlations between securities at short time scales
S. Valeyre, D. S. Grebenkov, S. Aboura
The correlation matrix is the key element in optimal portfolio allocation and risk management. In particular, the eigenvectors of the correlation matrix corresponding to large eige…
Ultrafast electrons dynamics reveal the high potential of InSe for hot carrier optoelectronics
Zhesheng Chen, Christine Giorgetti, Jelena Sjakste +9
We monitor the dynamics of hot carriers in InSe by means of two photons photoelectron spectroscopy (2PPE). The electrons excited by photons of 3.12 eV experience a manifold relaxat…
Evidence of nanoscale Anderson localization induced by intrinsic compositional disorder in InGaN/GaN quantum wells by scanning tunneling luminescence spectroscopy
W. Hahn, J. -M. Lentali, P. Polovodov +11
We present direct experimental evidences of Anderson localization induced by the intrinsic alloy compositional disorder of InGaN/GaN quantum wells. Our approach relies on the measu…
Semi-analytical computation of Laplacian Green functions in three-dimensional domains with disconnected spherical boundaries
D. S. Grebenkov, Sergey D. Traytak
We apply the generalized method of separation of variables (GMSV) to solve boundary value problems for the Laplace operator in three-dimensional domains with disconnected spherical…
