Spin polaron theory for the photoemission spectra of layered cobaltates

J. Chaloupka, G. Khaliullin

Recently, strong reduction of the quasiparticle peaks and pronounced incoherent structures have been observed in the photoemission spectra of layered cobaltates. Surprisingly, thes…

The origin of strong correlations and superconductivity in Na $_{x}$ CoO $_{2}$

G. Khaliullin, J. Chaloupka

We propose a minimal model resolving a puzzle of enigmatic correlations observed in sodium-rich Na $_{x}$ CoO $_{2}$ where one expects a simple, free motion of the dilute $S = 1/2$ holes do…

Spectroscopic distinction between the normal state pseudogap and the superconducting gap of cuprate high T_{c} superconductors

Li Yu, D. Munzar, A. V. Boris +6

We report on broad-band infrared ellipsometry measurements of the c-axis conductivity of underdoped RBa_{2}Cu_{3}O_{7-d} (R=Y, Nd, and La) single crystals. Our data provide a detai…
