Projective metrics and contraction principles for complex cones
Loic Dubois
In this article, we consider linearly convex complex cones in complex Banach spaces and we define a new projective metric on these cones. Compared to the hyperbolic gauge of Rugh,…
Physics of Silicene Stripes
A. Kara, C. Leandri, M. E. Davila +5
Silicene, a monolayer of silicon atoms tightly packed into a two-dimensional honeycomb lattice, is the challenging hypothetical reflection in the silicon realm of graphene, a one-a…
Crumpling transition and flat phase of polymerized phantom membranes
J. -P. Kownacki, D. Mouhanna
Polymerized phantom membranes are revisited using a nonperturbative renormalization group approach. This allows one to investigate both the crumpling transition and the low-tempera…
Three-Component Fermi Gas in a one-dimensional Optical Lattice
P. Azaria, S. Capponi, P. Lecheminant
We investigate the effect of the anisotropy between the s-wave scattering lengths of a three-component atomic Fermi gas loaded into a one-dimensional optical lattice. We find four…
Controllability of 3D incompressible Euler equations by a finite-dimensional external force
Hayk Nersisyan
In this paper, we study the control system associated with the incompressible 3D Euler system. We show that the velocity field and pressure of the fluid are exactly controllable in…
Mobility of D atoms on porous amorphous water ice surfaces under interstellar conditions
E. Matar, E. Congiu, F. Dulieu +2
Aims. The mobility of H atoms on the surface of interstellar dust grains at low temperature is still a matter of debate. In dense clouds, the hydrogenation of adsorbed species (i.e…
