Observation of vortices and hidden pseudogap from scanning tunneling spectroscopic studies of electron-doped cuprate superconductor $S r_{0.9} L a_{0.1} C u O_{2}$

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 $T_{c}$ (= 43 K) electron-type cuprate $S r_{0.9} L a_{0.1} C u O_{2}$ . Our spatially r…

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…

Macroscopic coherence effects in a mesoscopic system: Weak localization of thin silver films in an undergraduate lab

A. D. Beyer, M. Koesters, K. G. Libbrecht +1

We present an undergraduate lab that investigates weak localization in thin silver films. The films prepared in our lab have thickness, $a$ , between 60-200 Å, a mesoscopic length s…
