Ground state energy of N Frenkel excitons
W. V. Pogosov, M. Combescot
By using the composite many-body theory for Frenkel excitons we have recently developed, we here derive the ground state energy of Frenkel excitons in the Born approximation th…
Effect of pulse duration on the x-ray emission from Ar clusters in intense laser fields
Christophe Prigent, Emily Lamour, Jean-Pierre Rozet +3
We study experimentally and theoretically the production of characteristic Ka x-rays during the interaction of intense infrared laser pulse with large N~10^4-10^6 atoms/ argon clus…
Spin polarized two-dimensional electron gas embedded in semimagnetic quantum well : ground state, spin responses, spin excitations, Raman spectrum
F. Perez
We present theoretical aspects of spin polarized two dimensional electron gas (SP2DEG) which can be achieved in doped semimagnetic quantum wells. This original model system has bee…
From thermally activated to viscosity controlled fracture of biopolymer hydrogels
T. Baumberger, O. Ronsin
We report on rate-dependent fracture energy measurements over three decades of steady crack velocities in alginate and gelatin hydrogels. We evidence that, irrespective of gel ther…
Combination of Bloch oscillations with a Ramsey-Bordé interferometer : new determination of the fine structure constant
Malo Cadoret, Estefania De Mirandes, Pierre Cladé +5
We report a new experimental scheme which combines atom interferometry with Bloch oscillations to provide a new measurement of the ratio . By using Bloch oscilla…
Stability of a Bose-Einstein condensate revisited for composite bosons
M. Combescot, D. W. Snoke
It is known that elementary bosons condense in a unique state, not so much because this state has the lowest free particle energy but because it costs a macroscopic amount of energ…
