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…
