Droplet traffic in microfluidic networks: A simple model for understanding and designing
M. Schindler, A. Ajdari
We propose a simple model to analyze the traffic of droplets in microfluidic ``dual networks''. Such functional networks which consist of two types of channels, namely those access…
Nernst effect in the phase-fluctuating superconductor InO
P. Spathis, H. Aubin, A. Pourret +1
We present a study of the Nernst effect in amorphous 2D superconductor InO, whose low carrier density implies low phase rigidity and strong superconducting phase fluctuations.…
Behavior of Ising Spin Glasses in a Magnetic Field
Thomas Jorg, Helmut G. Katzgraber, Florent Krzakala
We study the existence of a spin-glass phase in a field using Monte Carlo simulations performed along a nontrivial path in the field--temperature plane that must cross any putative…
Microscopic heat from the energetics of stochastic phenomena
Ken Sekimoto
The energetics of the stochastic process has shown the balance of energy on the mesoscopic level. The heat and the energy defined there are, however, generally different from their…
Mechanical Response of a Small Swimmer Driven by Conformational Transitions
Ramin Golestanian, Armand Ajdari
A conformation space kinetic model is constructed to drive the deformation cycle of a three-sphere swimmer to achieve propulsion at low Reynolds number. We analyze the effect of an…
Phase Transitions and Computational Difficulty in Random Constraint Satisfaction Problems
Florent Krzakala, Lenka Zdeborová
We review the understanding of the random constraint satisfaction problems, focusing on the q-coloring of large random graphs, that has been achieved using the cavity method of the…
