Effect of Superconductivity on the Incommensurate Magnetic Response of Cuprate Superconductors
Dirk K. Morr, David Pines
We explain the effects of superconductivity on the incommensurate magnetic response observed in inelastic neutron scattering measurements on LaSrCuO. We…
Unconventional properties of superconducting cuprates
Andrey V. Chubukov, Dirk K. Morr
We present an explanation of the unusual peak/dip/hump features observed in photoemission experiments on Bi2212 at . We argue that these features arise from the interact…
The resonance peak in cuprate superconductors
Dirk K. Morr, David Pines
We pursue the consequences of a theory in which the resonance peak observed in inelastic neutron scattering (INS) experiments on underdoped and optimally doped YBaCuO$_{6+x…
Effect of next-nearest neighbor hopping on the spin dynamics in antiferromagnets
Dirk. K. Morr
Recently, inelastic neutron scattering (INS) experiments on the insulating parent compounds of high-T_c materials were analyzed to extract the value of the superexchange constant $…
Probing the susceptibility in cuprates using Ni impurities
Dirk K. Morr, Joerg Schmalian, Raivo Stern +1
Recent NMR experiments on (Bobroff et al. Phys. Rev. Lett. 79, 2117 (1997)) have shown that Ni impurities provide an important probe for the momentum…
