Quasiparticle excitations and dynamic susceptibilities in the BCS-BEC crossover
J. Bauer, A. C. Hewson
We study dynamic ground state properties in the crossover from weak (BCS) to strong coupling (BEC) superfluidity. Our approach is based on the attractive Hubbard model which is ana…

Field dependent quasiparticles in a strongly correlated local system II
J. Bauer, A. C. Hewson
We extend the renormalized quasiparticle description of the symmetric Anderson model in a magnetic field , developed in earlier work, to the non-symmetric model. The renormalize…

Polaronic Quasiparticles in a Strongly Correlated Electron Band
W. Koller, A. C. Hewson, D. M. Edwards
We show that a strongly renormalized band of polaronic quasiparticle excitations is induced at the Fermi level of an interacting many-electron system on increasing the coupling of…
