The electronic structure of the layered 4d transition metal oxide Sr2RhO4 is investigated by angle resolved photoemission. We find well-defined quasiparticle excitations with a highly anisotropic dispersion, suggesting a quasi-two-dimensional Fermi-liquid-like ground state. Markedly different from the isostructural Sr2RuO4, only two bands with dominant Rh 4dxz,zy character contribute to the Fer...
In framework of eigen-functional bosonization method, we introduce an imaginary phase field to uniquely represent electron correlation, and demonstrate that the Landau Fermi liquid theory and the Tomonaga-Luttinger liquid theory can be unified. It is very clear in this framework that the TomonagaLuttinger liquid behavior of one-dimensional interacting electron gases originates from their Fermi ...
Free fermions with a finite Fermi surface are known to exhibit an anomalously large entanglement entropy. The leading contribution to the entanglement entropy of a region of linear size L in d spatial dimensions is S∼L(d-1)logL, a result that should be contrasted with the usual boundary law S∼L(d-1). This term depends only on the geometry of the Fermi surface and on the boundary of the region i...
Magnetoresistance of the t.ittle organic metal, where BO is bis[ethylenedioxy)tetrathiafulvalene, is investigated. The angle dependent oscillations indicate the existence of cylindrical Fermi surface, and trie observed penodicity is consistent with the calculated band structure. The amplitude of the oscillation is very small in the direction where the Fermi surface touches trie zone boundary. T...
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 F...
