The crossover between the weak-coupling limit and strong-coupling limit provides important information for quantum bound states of interacting fermions. Here, Kasahara et al. report thermodynamic evidence for prevailing phase fluctuations of supercon

The (111)-2 × 1 surface of in situ cleaved heavily P- or B-doped Si is investigated by scanning tunnelling microscopy and spectroscopy at room temperature and at low temperature. P atoms have been identified on different sites of the Si(111)-2 × 1

The heavy-fermion compound CeCu_{6-x}Au_{x} has become a model system for unconventional magnetic quantum criticality. For small Au concentrations 0≤x0.16, the compound undergoes a structural transition from orthorhombic to monoclinic crystal symme

We report on light emission from biased metallic single-wall carbon nanotube (SWNT), multiwall carbon nanotube (MWNT) and few-layer graphene (FLG) devices. SWNT devices were assembled from tubes with different diameters in the range 0.7-1.5 nm. They

The π-conjugated oligomer consisting of ethynyl interlinked thiophene and benzene subunits C114H158O8S2Si2 has been deposited on clean Cu(111) substrates at room temperature using the pulse-injection method with tetrahydrofuran (THF) as solvent. Sca

We present a study of the Fermi surface of KFe$_2$As$_2$ single crystals. Quantum oscillations were observed in magnetostriction measured down to 50 mK and in magnetic fields $H$ up to 14 T. For $H \parallel c$, the calculated effective masses are in

The magnetic flux generated by the screening currents of a superconducting Nb film in the Meissner state is measured with a coaxial gradiometer in a weak magnetic field B. A peculiar position dependence is found when the sample surface is only slight

Das Konzept der Fermi-Flussigkeit hat entscheidend zum Verstandnis von Metallen beigetragen, in denen die Elektronen stark miteinander wechselwirken. Aufgrund der Korrespondenz zwischen Quasiteilchenanregungen einer Fermi-Flussigkeit und freien Elekt
