Dynamics of photoexcited Ba+ cations in 4He nanodroplets

Marcel Drabbels, Xiaohang Zhang, Alberto Hernando de Castro

We present a joint experimental and theoretical study on the desolvation of Ba+ cations in 4He nanodroplets excited via the 6p 6s transition. The experiments reveal an efficient desolvation process yielding mainly bare Ba+ cations and Ba+Hen exciplexes wit ...

Magnetic phase diagram of La2-xSrxCoO4 revised using muon-spin relaxation

Paul Gregory Freeman

We report the results of a muon-spin relaxation (mu SR) investigation of La2-xSrxCoO4, an antiferromagnetic insulating series which has been shown to support charge ordered and magnetic stripe phases and an hourglass magnetic excitation spectrum. We presen ...

Long time accuracy of Lie-Trotter splitting methods for Langevin dynamics

Assyr Abdulle, Gilles Vilmart

A new characterization of sufficient conditions for the Lie-Trotter splitting to cap- ture the numerical invariant measure of nonlinear ergodic Langevin dynamics up to an arbitrary order is discussed. Our characterization relies on backward error analysis ...

Computational Shifts in Theatrical Space

Andrew James Sempere

This dissertation describes a set of research projects that were conducted between 2012 and 2014 in order to answer the question how do computational ideas alter our understanding of place? Each project was produced in the context of the performing arts an ...

Effect of a noisy driving field on a bistable polariton system

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour, Grégory Chilpéric Sallen

We report on the effect of noise on the characteristics of the bistable polariton emission system. The present experiment provides a time-resolved access to the polariton emission intensity. We evidence the noise-induced transitions between the two stable ...

Reduced basis finite element heterogeneous multiscale method for quasilinear elliptic homogenization problems

Assyr Abdulle, Gilles Vilmart, Yun Bai

A reduced basis finite element heterogeneous multiscale method (RB-FE-HMM) for a class of nonlinear homogenization elliptic problems of nonmonotone type is introduced. In this approach, the solutions of the micro problems needed to estimate the macroscopic ...

Untangling the Mechanics and Topology in the Frictional Response of Long Overhand Elastic Knots

Pedro Miguel Nunes Pereira de Almeida Reis

We combine experiments and theory to study the mechanics of overhand knots in slender elastic rods under tension. The equilibrium shape of the knot is governed by an interplay between topology, friction, and bending. We use precision model experiments to q ...
