Effects of vortex pinning and thermal fluctuations on the Josephson plasma resonance in Tl2Ba2CaCu2O8 and YBa2Cu3O6.5.

Physical review letters

Dulić D, Hak SJ, van der Marel D, Hardy WN, Koshelev AE, Liang R, Bonn DA, Willemsen BA.
PMID: 11384308
Phys Rev Lett. 2001 May 14;86(20):4660-3. doi: 10.1103/PhysRevLett.86.4660.

We investigated the temperature dependence and c-axis magnetic field dependence of the Josephson plasma resonance in optimally doped Tl2Ba2CaCu2O8 thin films and underdoped YBa2Cu3O6.5 (YBCO) ortho-II single crystals using infrared spectroscopy. We obtained the c-axis penetration depths, at low...

A limit on spin-charge separation in high-Tc superconductors from the absence of a vortex-memory effect.


Bonn DA, Wynn JC, Gardner BW, Lin YJ, Liang R, Hardy WN, Kirtley JR, Moler KA.
PMID: 11780056
Nature. 2001 Dec 20-27;414(6866):887-9. doi: 10.1038/414887a.

There is a long-standing debate about whether spin-charge separation is the root cause of the peculiar normal-state properties and high superconducting transition temperatures of the high-Tc materials. In the proposed state of matter, the elementary excitations are not electron-like,...

Phys Rev Lett. 2003 Jun 13;90(23):237005. doi: 10.1103/PhysRevLett.90.237005. Epub 2003 Jun 13.

There has long been a discrepancy between microwave conductivity measurements in high temperature superconductors and the conductivity spectrum expected in the simplest models for impurity scattering in a d-wave superconductor. Here we present a new type of broadband measurement...

Photoinduced changes of reflectivity in single crystals of YBa2Cu3O6.5 (ortho II).

Physical review letters

Segre GP, Gedik N, Orenstein J, Bonn DA, Liang R, Hardy WN.

Phys Rev Lett. 2002 Apr 01;88(13):137001. doi: 10.1103/PhysRevLett.88.137001. Epub 2002 Mar 14.

We report measurements of the photoinduced change in reflectivity of an untwinned single crystal of YBa2Cu3O6.5 in the ortho II structure. The decay rate of the transient change in reflectivity is found to decrease rapidly with decreasing temperature and,...

Spinel and perovskite with distinctive crystal structures are two of the most popular material families in electrocatalysis, which, however, usually show poor conductivity, causing a negative effect on the charge transfer process during electrochemical reactions. Herein, a highly conductive...

Logarithmic Upturn in Low-Temperature Electronic Transport as a Signature of d-Wave Order in Cuprate Superconductors.

Physical review letters

Zhou X, Peets DC, Morgan B, Huttema WA, Murphy NC, Thewalt E, Truncik CJS, Turner PJ, Koenig AJ, Waldram JR, Hosseini A, Liang R, Bonn DA, Hardy WN, Broun DM.
PMID: 30636125
Phys Rev Lett. 2018 Dec 28;121(26):267004. doi: 10.1103/PhysRevLett.121.267004.

In cuprate superconductors, high magnetic fields have been used extensively to suppress superconductivity and expose the underlying normal state. Early measurements revealed insulatinglike behavior in underdoped material versus temperature T, in which resistivity increases on cooling with a puzzling...

An efficient and practical method for the synthesis of medicinally important acridines from readily available o-aminoaryl ketones and arylboronic acids was developed using copper(II)-mediated relay reactions that involve intermolecular Chan-Lam cross-coupling and subsequent intramolecular Friedel-Crafts-type reactions. A sole promoter,...
