Miles' mechanism for generating surface water waves by wind, in finite water depth and subject to constant vorticity flow

Autor: Kern, Norbert, Chaubet, Christophe, Kraenkel, Roberto, Manna, Miguel

The Miles theory of wave amplification by wind is extended to the case of finite depth h and a shear flow with (constant) vorticity {\Omega}. Vorticity is characterised through the non-dimensional parameter {\nu} = {\Omega} U_1 /g, where g the gravit

Anharmonicity and asymmetry of Landau levels for a two-dimensional electron gas

Autor: Bonifacie, Stephane, Chaubet, Christophe, Jouault, Benoit, Raymond, Andre

We calculate the density of states of a two dimensional electron gas located at the interface of a GaAlAs/GaAs heterojunction. The disorder potential which is generally created by a single doping layer behind a spacer, is here enhanced by the presenc

International audience; A variational theory is presented of A1− and A2− centers, i.e., of a negative acceptor ion localizing one and two conduction electrons, respectively, in a GaAs/GaAlAs quantum well in the presence of a magnetic field parall

International audience; We demonstrate theoretically that bound acceptors states of a two dimensional electron gas in quantizing magnetic field can localize two electrons on a same site. We calculate the energies and wave functions of the second quan
