Analysis of the elementary excitations in high-Tc cuprates: Explanation of the new energy scale observed by angle-resolved photoemission spectroscopy

Manske D.; Eremin I.; Bennemann K. (2001)

Analysis of the energy and momentum dependence of elementary excitations in high-Tc cuprates were performed. The elementary excitations in high-Tc superconductors were the result of the coupling to spin fluctuations. The ...
Electronic theory for superconductivity in Sr2RuO4: Triplet pairing due to spin-fluctuation exchange

Eremin I.; Manske D.; Joas C.; Bennemann K. (2002)

Using a Hubbard Hamiltonian for the three electronic bands crossing the Fermi level in Sr2RuO4, we calculate the band structure and spin susceptibility χ(q, w) in quantitative agreement with nuclear magnetic resonance (NMR) ...
Electronic theory for the magnetic anisotropy in Sr2RuO 4

Eremin I.; Manske D.; Tarento J.; Bennemann K. (2002)

Using a three-band Hubbard Hamiltonian we calculated within the random-phase-approximation the spin susceptibility, χ(q, ω), and NMR spin-lattice relaxation rate 1/T1, in the normal state of the triplet superconductor ...
Elementary excitations in high-Tc cuprates: Kink and resonance peak

Manske D.; Eremin I.; Bennemann K. (2004)

Assuming the exchange of antiferromagnetic spin fluctuations as the Cooper pairing mechanism we calculate the kink-like change of the quasiparticle velocity seen by ARPES resulting from the coupling to spin fluctuations ...
Novel neutron resonance mode in dx2-y2-wave superconductors

Eremin I.; Morr D.; Chubukov A.; Bennemann K.; Norman M. (2005)

We show that a new resonant magnetic excitation at incommensurate momenta, observed recently by inelastic neutron scattering experiments on YBa 2Cu3O6.85 and YBa2Cu 3O6.6, is a spin exciton. Its location in the Brillouin ...
Renormalization of the elementary excitations in hole- and electron-doped cuprates due to spin fluctuations

Manske D.; Eremin I.; Bennemann K. (2003)

Extending our previous studies we present results for the doping, momentum, frequency, and temperature dependence of the kinklike change of the quasiparticle velocity resulting from the coupling to spin fluctuations. In ...
Theory for electron- and hole-doped cuprate superconductors: D-wave symmetry order parameter

Manske D.; Eremin I.; Bennemann K. (2001)

Using as a model the Hubbard Hamiltonian, we determine various basic properties of electron-and hole-doped cuprate superconductors for a spin-fluctuation-induced pairing mechanism. We find for both hole-and electron-doped ...
