Noise-induced escape from bifurcating attractors: Symplectic approach in the weak-noise limit
Jonathan Demaeyer, Pierre Gaspard
The effect of noise is studied in one-dimensional maps undergoing transcritical, tangent, and pitchfork bifurcations. The attractors of the noiseless map become metastable states i…
Heat transport in stochastic energy exchange models of locally confined hard spheres
Pierre Gaspard, Thomas Gilbert
We study heat transport in a class of stochastic energy exchange systems that characterize the interactions of networks of locally trapped hard spheres under the assumption that ne…
Discrete- versus continuous-state descriptions of the F1-ATPase molecular motor
E. Gerritsma, P. Gaspard
A discrete-state model of the F1-ATPase molecular motor is developed which describes not only the dependences of the rotation and ATP consumption rates on the chemical concentratio…
Fractality of the non-equilibrium stationary states of open volume-preserving systems: II. Galton boards
Felipe Barra, Pierre Gaspard, Thomas Gilbert
Galton boards are models of deterministic diffusion in a uniform external field, akin to driven periodic Lorentz gases, here considered in the absence of dissipation mechanism. Ass…
Non-Abelian optical lattices: Anomalous quantum Hall effect and Dirac Fermions
N. Goldman, A. Kubasiak, A. Bermudez +3
We study the properties of an ultracold Fermi gas loaded in an optical square lattice and subjected to an external and classical non-Abelian gauge field. We show that this system c…
Ultracold atomic gases in non-Abelian gauge potentials: The case of constant Wilson loop
N. Goldman, A. Kubasiak, P. Gaspard +1
Nowadays it is experimentally feasible to create artificial, and in particular, non-Abelian gauge potentials for ultracold atoms trapped in optical lattices. Motivated by this fact…
