Exploring fusion at extreme sub barrier energies with weakly bound nuclei

Author(s) : Shrivastava, A. , Navin, A. , Lemasson, A. , Ramachandran, K. , Nanal, V. , Rejmund, M. , Hagino, K. , Ichikawa, T. , Bhattacharyya, S.
Description : Results of measurement of residues formed in fusion of 6Li with 198Pt in the energy range of 0.68< E/$V_b$ <1.3 using a new sensitive off-beam technique are reported. The fusion excitation function and the derived average angular momenta do not indicate a change of slope at deep sub-barrier energies...

Entropy-driven excitation-energy sorting in superfluid fission dynamics

Author(s) : Schmidt, K.-H. , Jurado, B.
Description : It is shown that the constant-temperature behaviour of nuclei in the superfluid regime leads to an energy-sorting process if two nuclei are in thermal contact, as is the case in the fission process. This effect explains for the first time why an increase of the initial excitation energy leads an inc...

Prolate-Spherical Shape Coexistence at N=28 in $^{44}$S

Author(s) : Force, C. , Grévy, S. , Gaudefroy, L. , Sorlin, O. , Caceres, L. , Rotaru, F. , Mrazek, J. , Achouri, N.L. , Angélique, J.C.
Description : The structure of $^{44}$S has been studied using delayed $\gamma$ and electron spectroscopy at \textsc{ganil}. The decay rates of the 0$^+_2$ isomeric state to the 2$^+_1$ and 0$^+_1$ states have been measured for the first time, leading to a reduced transition probability B(E2~:~2$^{+}_1$$\rightarr...

Single cells spreading on a protein lattice adopt an energy minimizing shape.

Author(s) : Vianay, Benoit , Käfer, Jos , Planus, Emmanuelle , Block, Marc , Graner, François , Guillou, Hervé
Description : When spreading onto a protein microlattice living cells spontaneously acquire simple shapes determined by the lattice geometry. This suggests that, on a lattice, living cells' shapes are in thermodynamic metastable states. Using a model at thermodynamic equilibrium we are able to reproduce the obser...

Disorder and transport in cuprates: weak localization and magnetic contributions

Author(s) : Rullier-Albenque, F. , Alloul, H. , Tourbot, R.
Description : We report resistivity measurements in underdoped YBa$_{2}$Cu$_{3}$O$_{6.6}\,$and overdoped Tl$_{2}$Ba$_{2}$CuO$_{6+x}$ single crystals in which the concentration of defects in the CuO$_{2}$ planes is controlled by electron irradiation. Low $T$ upturns of the resistivity are observed in both cases fo...

Edge Logarithmic Corrections Probed by Impurity NMR

Author(s) : Brunel, V. , Bocquet, M. , Jolicoeur, T.
Description : Semi-infinite quantum spin chains display spin autocorrelations near the boundary with power-law exponents that are given by boundary conformal field theories. We show that NMR measurements on spinless impurities that break a quantum spin chain lead to a spin-lattice relaxation rate $1/T_{1}^{edge}$...

Kinetic equations for long-wavelength excitations of the quark-gluon plasma

Author(s) : Blaizot, J.-P. , Iancu, E.
Description : We show that longwavelength excitations of the quark-gluon plasma are described by simple kinetic equations which represent the exact equations of motion at leading order in $ g. $ Properties of the so-called \lq\lq hard thermal loops\rq\rq , i.e. the dominant contributions to amplitudes with soft e...
