On the relation between gradient flows and the large-deviation principle, with applications to Markov chains and diffusion

Alexander Mielke, D. R. Michiel Renger, Mark A. Peletier

Motivated by the occurrence in rate functions of time-dependent large-deviation principles, we study a class of non-negative functions that induce a flow, given by $\m…

Marangoni spreading due to a localized alcohol supply on a thin water film

José Federico Hernández-Sánchez, Antonin Eddi, J. H. Snoeijer

Bringing the interfaces of two miscible fluids into contact naturally generates strong gradients in surface tension. Here we investigate such a Marangoni-driven flow by continuousl…

Experimental study of the spatio-temporal development of meter-scale negative discharge in air

P. O. Kochkin, A. P. J. van Deursen, U. Ebert

We study the development of a negative discharge driven by a Marx generator of about 1 MV in an air gap of 1 up to 1.5 meter, at standard temperature and pressure. We show the evol…

Uniqueness in quadratic and hyperbolic 0-1 programming problems

Vladimir G. Deineko, Bettina Klinz, Gerhard J. Woeginger

We analyze the question of deciding whether a quadratic or a hyperbolic 0-1 programming instance has a unique optimal solution. Both uniqueness questions are known to be NP-hard, b…

Drops on soft solids: Free energy and double transition of contact angles

Luuk A. Lubbers, Joost H. Weijs, Lorenzo Botto +3

The equilibrium shape of liquid drops on elastic substrates is determined by minimising elastic and capillary free energies, focusing on thick incompressible substrates. The proble…

An online version of Rota's basis conjecture

Guus P. Bollen, Jan Draisma

Rota's basis conjecture states that in any square array of vectors whose rows are bases of a fixed vector space the vectors can be rearranged within their rows in such a way that a…

Wireless network control of interacting Rydberg atoms

Jaron Sanders, Rick van Bijnen, Edgar Vredenbregt +1

We identify a relation between the dynamics of ultracold Rydberg gases in which atoms experience a strong dipole blockade and spontaneous emission, and a stochastic process that mo…

Heat flux scaling in turbulent Rayleigh-Bénard convection with an imposed longitudinal wind

Andrea Scagliarini, Armann Gylfason, Federico Toschi

We present a numerical study of Rayleigh-Bénard convection disturbed by a longitudinal wind. Our results show that under the action of the wind, the vertical heat flux through the…
