Enhancement of the electron spin memory by localization on donors in a quantum well
J. Tribollet, E. Aubry, G. Karczewski +4
We present easily reproducible experimental conditions giving long electron spin relaxation and dephasing times at low temperature in a quantum well. The proposed system consists i…
Frictional dissipation of polymeric solids vs interfacial glass transition
Lionel Bureau, Christiane Caroli, Tristan Baumberger
We present single contact friction experiments between a glassy polymer and smooth silica substrates grafted with alkylsilane layers of different coverage densities and morphologie…
Quasiparticle spectrum of the cuprate BiSrCaCuO: Possible connection to the phase diagram
W. Sacks, T. Cren, D. Roditchev +1
We previously introduced [T. Cren et al., Europhys. Lett. 52, 203 (2000)] an energy-dependant gap function, , that fits the unusual shape of the quasiparticle (QP) spectrum f…
Fracture of a biopolymer gel as a viscoplastic disentanglement process
Tristan Baumberger, Christiane Caroli, David Martina
We present an extensive experimental study of mode-I, steady, slow crack dynamics in gelatin gels. Taking advantage of the sensitivity of the elastic stiffness to gel composition a…
Solvent control of crack dynamics in a reversible hydrogel
Tristan Baumberger, Christiane Caroli, David Martina
The resistance to fracture of reversible biopolymer hydrogels is an important control factor of the cutting/slicing and eating characteristics of food gels. It is also critical for…
Local Tunneling Study of Three-Dimensional Order Parameter in the -band of Al-doped MgB Single Crystals
F. Giubileo, F. Bobba, A. Scarfato +5
We have performed local tunneling spectroscopy on high quality MgAlB single crystals by means of Variable Temperature Scanning Tunneling Spectroscopy (STS) in magne…
