28th INTERNATIONAL SYMPOSIUM ON SUPERCONDUCTIVITY
(ISS 2015)
 
Selected Plenary and Invited Presentations
 
 
FOREWORD
 
This Preview includes one plenary and three invited slide presentations from the recent International Superconductivity Symposium (ISS 2015) meeting, held from November 16 to 18, 2015 at Funabori, Tokyo, Japan.
 
In his special plenary talk (CRP66), Shin-ichi Uchida presented and discussed the long way to higher Tc superconductors.  In chronological order of discoveries, he highlighted the cuprates, MgB2, Fe-arsenides/selenides, and commented on possibilities to discover still higher Tc, beyond the record high values attained in cuprates over twenty years ago.  Mentioned were the very recent observations of high-Tc in FeSe monolayers, the yet to be confirmed results near 200 K in sulphur hydride under very high pressures and the transient  Tc > 300 K in underdoped YBCO excited by laser THz light pulses.
 
Among the invited presentations, electronics is represented by the Lixing You’s annotated review (STP515) of recent results in superconducting nanowire single photon detectors for applications such as quantum information communication, laser ranging, single photon imaging, and others.  The review emphasizes own results obtained at SIMIT in Shanghai, China.
 
M. Eisterer’s annotated presentation (STP514) covers investigations of current flow in polycrystalline iron-based superconductors by means of scanning Hall probe microscopy (SHPM) to explore possibilities for advancing performance of such granular materials.  A Josephson intergranular coupling model predicts increase of macroscopic current density with decreasing grain size, which was confirmed by experiments.
 
Xin Yao’s presentation (STP513) summarizes recent progress in growing bulk REBCO superconductors for practical applications, emphasizes the promise of light rare earth (RE) compounds and discusses superheating effects.  Thin REBCO films with high thermal stability have been successfully employed as seed materials in inducing growth of thick films, single crystals, and single-domain bulk materials.
