Observation of vortices and hidden pseudogap from scanning tunneling spectroscopic studies of electron-doped cuprate superconductor
M. L. Teague, A. D. Beyer, M. S. Grinolds +2
We present the first demonstration of vortices in an electron-type cuprate superconductor, the highest (= 43 K) electron-type cuprate . Our spatially r…
Scanning tunneling spectroscopic evidence for magnetic field-induced microscopic orders in the high- superconductor YBaCuO
A. D. Beyer, M. S. Grinolds, M. L. Teague +2
We report spatially resolved tunneling spectroscopic evidence for field-induced microscopic orders in a high- superconductor . The spectral characteristi…
Macroscopic evidence for quantum criticality and field-induced quantum fluctuations in cuprate superconductors
A. D. Beyer, V. S. Zapf, H. Yang +5
We present macroscopic experimental evidence for field-induced microscopic quantum fluctuations in different hole- and electron-type cuprate superconductors with varying doping lev…
Competing orders and the doping and momentum dependent quasiparticle excitations in cuprate superconductors
A. D. Beyer, C. -T. Chen, M. S. Grinolds +2
The low-energy quasiparticle excitations in hole- and electron-type cuprate superconductors are investigated via both experimental and theoretical means. It is found that the dopin…
Competing Orders and Quantum Phase Fluctuations on the Low-Energy Excitations and Pseudogap Phenomena of Cuprate Superconductors
C. -T. Chen, A. D. Beyer, N. -C. Yeh
We investigate the low-energy quasiparticle excitation spectra of cuprate superconductors by incorporating both superconductivity (SC) and competing orders (CO) in the bare Green's…
Experimental Investigation of the Competing Orders and Quantum Criticality in Hole- and Electron-Doped Cuprate Superconductors
N. -C. Yeh, C. -T. Chen, V. S. Zapf +5
We investigate the issues of competing orders and quantum criticality in cuprate superconductors via experimental studies of the high-field thermodynamic phase diagrams and the qua…
