NSF-ITP-93-16 cond-mat/9301034 Lower Bound on the Energy Gap at Precise Locations
نویسنده
چکیده
Recent inelastic-neutron-scattering measurements of a low-energy phonon in Bi 2 Sr 2 CaCu 2 O 8 provide enough information to place a lower bound on the energy gap magnitude at precise locations on the Fermi surface. Measurements of a few low-energy phonons should indicate whether the gap symmetry is d x 2 −y 2. Further measurements could map out the angle-resolved gap magnitude on the entire Fermi surface.

We propose field theories for the bulk and edge of a quantum Hall state in the universality class of the Haldane-Rezayi wavefunction. The bulk theory is associated with the c = −2 conformal field theory. The topological properties of the state, such as the quasiparticle braiding statistics and ground state degeneracy on a torus, may be deduced from this conformal field theory. The 10-fold degen...

Submitted for the MAR06 Meeting of The American Physical Society Strong correlation effects in the IR Hall Effect in the cuprates: an overview1 H.D. DREW, University of Maryland — The Hall Effect at infrared frequencies provides a sensitive probe of strong interaction effects in strongly correlated metals. Experimental results show that the strong interaction effects inter the Hall conductivity...
متن کاملHydrogen storage in pillared Li-dispersed boron carbide nanotubes
Ab initio density-functional theory study suggests that pillared Li-dispersed boron carbide nanotubes is capable of storing hydrogen with a mass density higher than 6.0 weight% and a volumetric density higher than 45 g/L. The boron substitution in carbon nanotube greatly enhances the binding energy of Li atom to the nanotube, and this binding energy (~ 2.7 eV) is greater than the cohesive energ...

متن کاملDiffusion Poles and the Anderson Transition
In the recent series of papers (cond-mat/0402471, cond-mat/0403618, condmat/0407618, cond-mat/0501586), Janis and Kolorenc discussed the role of the diffision poles in the Anderson transition theory. Their picture contradicts the general principles and is shown below to be completely misleading. Correct setting of the problem is given and the contemporary situation is discussed. The critical re...
