Quantum Critical Point in Electron-Doped Cuprates
C. Kusko, R. S. Markiewicz, M. Lindroos +1
We analyze doping dependent spectral intensities and Fermi surface maps obtained recently in NdCeCuO (NCCO) via high resolution ARPES measurements, and show t…
Photoemission from Ordered Stripe Phases
R. S. Markiewicz, C. Kusko
A phase separation model for stripes has found good agreement with photoemission experiments and with other studies which suggest a termination of the striped phase in the slightly…
Comment on "Predominantly Superconducting Origin ...", by N. Miyakawa, et al
R. S. Markiewicz, C. Kusko
Recent tunneling studies in Bi2Sr2CaCu2O8 suggest that the pseudogap is caused by superconducting fluctuations. By reanalyzing this data, we show that instead there is a second non…
Tunneling and Photoemission in an SO(6) Superconductor
R. S. Markiewicz, C. Kusko, M. T. Vaughn
Combining the results of tunneling, photoemission and thermodynamic studies, the pseudogap is unambiguously demonstrated to be caused by Van Hove nesting: a splitting of the densit…
Tunneling Studies of Pseudogaps: a Comment
R. S. Markiewicz, C. Kusko
Recent tunneling observations of a pseudogap in Bi_2Sr_2CaCu_2O_{8+delta} are not necessarily evidence that the pseudogap is associated with superconducting fluctuations. The data…
