Hybridization gap in heavy fermion compounds.
We report the results of optical studies of new heavy fermion compounds YbFe(4)Sb(12) and CeRu(4)Sb(12). We show that these compounds, as well as several other heavy fermion materials with a nonmagnetic ground state, obey a universal scaling relationship between the quasiparticle effective mass m(*) and the magnitude of the energy gap Delta in the excitation spectrum. This result is in accord w...
متن کاملBridging the Gender Gap in Quantum Physics
Works Cited 71-73 Acknowledgments: First and foremost, my sincere gratitude goes to the Pomona College Physics Department for their support of this slightly unconventional project. Being able to work on a senior exercise of tremendous personal interest meant so much to me. Particular thanks to Prof. Moore, Kwok, Edwards, Tanenbaum, and Mawhorter for the major parts they all played in this proje...
متن کاملThe non-forward BFKL amplitude and rapidity gap physics
We discuss the BFKL approach to processes with large momentum transferred through a rapidity gap. The Mueller and Tang scheme to the BFKL non-forward parton-parton elastic scattering amplitude at large t, is extended to include higher conformal spins. The new contributions are found to decrease with increasing energy, as follows from the gluon reggeisation phenomenon, and to vanish for asymptot...
متن کاملLocalized excitation in the hybridization gap in YbAl3.
The intermediate valence compound YbAl3 exhibits a broad magnetic excitation in the inelastic neutron scattering spectrum with characteristic energy E1 approximately 50 meV, equal to the Kondo energy (T(K) approximately 600-700 K). In the low temperature (T < T(coh) approximately 40 K) Fermi liquid state, however, a new peak in the scattering occurs at E2 approximately 33 meV, which lies in the...
