Quantum Criticality in Ferromagnetic Single-Electron Transistors
Stefan Kirchner, Lijun Zhu, Qimiao Si +1
Considerable evidence exists for the failure of the traditional theory of quantum critical points (QCPs), pointing to the need to incorporate novel excitations. The destruction of…
Magnetic Quantum Phase Transitions in Kondo Lattices
Qimiao Si, Jian-Xin Zhu, D. R. Grempel
The identification of magnetic quantum critical points in heavy fermion metals has provided an ideal setting for experimentally studying quantum criticality. Motivated by these exp…
Molecular Probe of Pairing in the BEC-BCS Crossover
G. B. Partridge, K. E. Strecker, R. I. Kamar +2
We have used optical molecular spectroscopy to probe the many-body state of paired Li atoms near a broad Feshbach resonance. The optical probe projects pairs of atoms onto a vi…
Extracting contact effects in organic field-effect transistors
B. H. Hamadani, D. Natelson
Contact resistances between organic semiconductors and metal electrodes have been shown to play a dominant role in electronic charge injection properties of organic field-effect tr…
Kondo resonances and anomalous gate dependence of electronic conduction in single-molecule transistors
L. H. Yu, Z. K. Keane, J. W. Ciszek +5
We report Kondo resonances in the conduction of single-molecule transistors based on transition metal coordination complexes. We find Kondo temperatures in excess of 50 K, comparab…
The Reversible Phase Transition of DNA-Linked Colloidal Gold Assemblies
Young Sun, Nolan C. Harris, Ching-Hwa Kiang
We present direct evidence for a reversible phase transition of DNA-linked colloidal gold assemblies. Transmission electron microscopy and optical absorption spectroscopy are used…
