Spectroscopy as a tool to detect multinuclear Cu(II)–triethanolamine complexes in aqueous solution

28-May-2018 | Petra Lommens; Pieter Tack; Luce Vander Elst; Isabel Van Driessche; Laszlo Vincze; Davy Sinnaeve, Dalton Transactions, 2018

Complexes of Cu(ii) with triethanolamine (TEA) are widely used in aqueous precursor solutions of Cu-based catalysts and metal oxides such as YBa2Cu3O7−δ superconductors. An outstanding question is whether such complexes are multinuclear in solution. Here, we use various spectroscopic techniques ...

Quantum corral effects on competing orders and electronic states in chiral d + id or f-wave superconductors

28-May-2018 | Xian-Jun Zuo, Physical Chemistry Chemical Physics, 2018

Self-consistent calculations are performed to characterize the quantum corral effects on the electronic states of chiral d + id or f-wave superconductors in this paper. A variety of spatial structures of competing orders are revealed in the presence of ferromagnetic nano-corrals, and ...

Strain-induced modulations of electronic structure and electron–phonon coupling in dense H3S

26-May-2018 | Chang Liu; Hang Zhai; Ying Sun; Weiguang Gong; Yan Yan; Quan Li; Weitao Zheng, Physical Chemistry Chemical Physics, 2018

A ∼200 K superconducting phase in dense hydrogen sulfide is an important milestone for the development of novel superconductors with high critical temperature. Here, we systematically studied the effect of uniaxial strain on the electronic and superconducting properties in dense H3S using density ...

Superconductivity in two-dimensional phosphorus carbide ([small beta]0-PC)

24-May-2018 | Bao-Tian Wang; Peng-Fei Liu; Tao Bo; Wen Yin; Olle Eriksson; Jijun Zhao; Fangwei Wang, Physical Chemistry Chemical Physics, 2018

Two-dimensional (2D) boron has been predicted to show superconductivity. However, intrinsic 2D carbon and phosphorus have not been reported to be superconductors, which has inspired us to study the superconductivity of their mixture. Here we performed first-principles calculations for the ...

Fully gapped d-wave superconductivity in CeCu2Si2 [Applied Physical Sciences]

22-May-2018 | Guiming Pang; Michael Smidman; Jinglei Zhang; Lin Jiao; Zongfa Weng; Emilian M. Nica; Ye Chen; Wenbing Jiang; Yongju ..., Proceedings of the National Academy of Sciences current issue, 2018

Identifying the gap structure of superconductors is vital for understanding the underlying pairing mechanism of the Cooper pairs. The first heavy fermion superconductor to be discovered, CeCu2Si2, was thought to be a d-wave superconductor with gap nodes, until recent specific heat measurements ...

Higgs mode in a strongly interacting fermionic superfluid

21-May-2018 | A. Behrle; T. Harrison; J. Kombe; K. Gao; M. Link; J.-S. Bernier; C. Kollath; M. Köhl, Nature Physics, 2018

Higgs and Goldstone modes are possible collective modes of an order parameter on spontaneously breaking a continuous symmetry. Whereas the low-energy Goldstone (phase) mode is always stable, additional symmetries are required to prevent the Higgs (amplitude) mode from rapidly decaying into ...

Enhanced spin pumping into superconductors provides evidence for superconducting pure spin currents

16-Apr-2018 | Kun-Rok Jeon; Chiara Ciccarelli; Andrew J. Ferguson; Hidekazu Kurebayashi; Lesley F. Cohen; Xavier Montiel; Matthias ..., Nature Materials, 2018

Unlike conventional spin-singlet Cooper pairs, spin-triplet pairs can carry spin1,2. Triplet supercurrents were discovered in Josephson junctions with metallic ferromagnet spacers, where spin transport can occur only within the ferromagnet and in conjunction with a charge current. Ferromagnetic ...

Charge quantum interference device

09-Apr-2018 | S. E. Graaf; S. T. Skacel; T. Hönigl-Decrinis; R. Shaikhaidarov; H. Rotzinger; S. Linzen; M. Ziegler; U. H ..., Nature Physics, 2018

The demonstration of coherent quantum phase slips (CQPS) in disordered superconductors has opened up a new route towards exploring the fundamental charge–phase duality in superconductors, with the promise of devices with new functionalities and a robust quantum current standard based on CQPS. ...

Entropy, Vol. 20, Pages 183: Equilibrium States in Two-Temperature Systems

09-Mar-2018 | Curado, Evaldo M. F.; Nobre, Fernando D., Entropy, 2018

Entropy, Vol. 20, Pages 183: Equilibrium States in Two-Temperature Systems Entropy doi: 10.3390/e20030183 Authors: Evaldo Curado Fernando Nobre Systems characterized by more than one temperature usually appear in nonequilibrium statistical mechanics. In some cases, e.g., glasses, ...

Topological antiferromagnetic spintronics

02-Mar-2018 | Libor Šmejkal; Yuriy Mokrousov; Binghai Yan; Allan H. MacDonald, Nature Physics, 2018

The recent demonstrations of electrical manipulation and detection of antiferromagnetic spins have opened up a new chapter in the story of spintronics. Here, we review the emerging research field that is exploring the links between antiferromagnetic spintronics and topological structures in real ...
