Random-phase approximation study of collective excitations in the Bose-Fermi mixed condensate of alkali-metal gases
T. Sogo, T. Miyakawa, T. Suzuki +1
We perform Random Phase Approximation (RPA) study of collective excitations in the bose-fermi mixed degenerate gas of Alkali-metal atoms at T=0. The calculation is done by diagonal…
Sum Rule Approach to Collective Oscillations of Boson-Fermion Mixed Condensate of Alkali Atoms
T. Miyakawa, T. Suzuki, H. Yabu
The behavior of collective oscillations of a trapped boson-fermion mixed condensate is studied in the sum rule approach. Mixing angle of bosonic and fermionic multipole operators i…
Induced instability for boson-fermion mixed condensate of Alkali atoms due to attractive boson-fermion interaction
T. Miyakawa, T. Suzuki, H. Yabu
Instabilities for boson-fermion mixed condensates of trapped Alkali atoms due to the boson-fermion attractive interaction are studied using a variational method. Three regions are…
S-wave Scattering Length from Effective Positronium-Positronium Interaction for Bose-Einstein Condensates
K. Oda, T. Miyakawa, H. Yabu +1
The s-wave scattering length for the Positronium-Positronium interaction is estimated semi-phenomenologically with the long-range van der Waals force and the short-range repulsive…
Static Properties of Trapped Bose-Fermi Mixed Condensate of Alkali Atoms
T. Miyakawa, K. Oda, T. Suzuki +1
Static properties of a bose-fermi mixture of trapped potassium atoms are studied in terms of coupled Gross-Pitaevskii and Thomas-Fermi equations for both repulsive and attractive b…
