Spin excitations in fermion condensates
Tomoyuki Maruyama, George F. Bertsch
We investigate collective spin excitations in two-component fermion condensates with special consideration of unequal populations of the two components. The frequencies of monopole…
Molecular transitions in Fermi condensates
Aurel Bulgac, George F. Bertsch
We discuss the transition of fermion systems to a condensate of Bose dimers, when the interaction is varied by use of a Feshbach resonance. We argue that there is an intermediate p…
Scaling theory of excitations in trapped fermionic condensates
G. F. Bertsch, A. Bulgac, R. A. Broglia
Formulas are derived for the coupled quadrupolar and monopolar oscillations of a fermion condensate trapped in a axially symmetric harmonic potential. We consider two-component con…
Variational RPA for the Mie resonance in jellium
G. F. Bertsch, C. Guet, K. Hagino
The surface plasmon in simple metal clusters is red-shifted from the Mie frequency, the energy shift being significantly larger than the usual spill-out correction. Here we develop…
Application of time-dependent density-functional theory to electron-ion couplng in ethylene
G. F. Bertsch, J. Giansiracusa, K. Yabana
To examine the applicability of the time-dependent density-functional theory (TDDFT) for treating the electron-nucleus coupling in excited states, we calculate the strength distrib…
Excited states dynamics in time-dependent density functional theory: high-field molecular dissociation and harmonic generation
Alberto Castro, M. A. L. Marques, Julio A. Alonso +2
We present a theoretical description of femtosecond laser induced dynamics of the hydrogen molecule and of singly ionised sodium dimers, based on a real-space, real-time, implement…
