Fractional power-law susceptibility and specific heat in low temperature insulating state of o-TaS_{3}
K. Biljakovic, M. Miljak, D. Staresinic +4
Measurements of the magnetic susceptibility and its anisotropy in the quasi-one-dimensional system o-TaS_{3} in its low-T charge density wave (CDW) ground state are reported. Both…
Spectroscopic signatures of a bandwidth-controlled Mott transition at the surface of 1T-TaSe
L. Perfetti, A. Georges, S. Florens +5
High-resolution angle-resolved photoemission (ARPES) data show that a metal-insulator Mott transition occurs at the surface of the quasi-two dimensional compound TaSe. The tran…
What the resonance peak does
S. V. Borisenko, A. A. Kordyuk, T. K. Kim +7
High-resolution angle-resolved photoemission with variable excitation energies is used to disentangle bilayer splitting effects and intrinsic (self-energy) effects in the electroni…
Observation of an unconventional metal-insulator transition in overdoped CuO_2 compounds
F. Venturini, M. Opel, T. P. Devereaux +7
The electron dynamics in the normal state of BiSrCaCuO is studied by inelastic light scattering over a wide range of doping. A strong anisotropy of the electron…
Phonon anomaly at the charge ordering transition in 1T-TaS2
L. V. Gasparov, K. G. Brown, A. C. Wint +5
The infrared reflectance of the transition metal chalcogenide 1T-TaS2 has been measured at temperatures from 30K to 360K over 30-45,000cm^-1 (4meV-5.5eV). The optical conductivity…
Doping dependence of the Fermi surface in Bi(Pb)2212
A. A. Kordyuk, S. V. Borisenko, M. S. Golden +7
A detailed and systematic ARPES investigation of the doping-dependence of the normal state Fermi surface (FS) of modulation-free Bi(Pb)2212 is presented. The FS does not change in…
