Quantum calculation of vortices in the inner crust of neutron stars
The self-consistent mean-field quantum mechanical solution of a vortex and a nucleus immersed in a sea of free neutrons, a scenario representative of the inner crust of neutron stars, is presented
Semiclassical Approximation to Neutron Star Superfluidity Corrected for Proximity Effects
The inner crust of a neutron star is a superfluid and inhomogeneous system, consisting of a lattice of nuclei immersed in a sea of neutrons. We perform a quantum calculation of the associated pairing
Folding and aggregation of designed proteins.
It is found that protein aggregation is determined by elementary structures controlled by local contacts among some of the most strongly interacting amino acids and formed at an early stage in the folding process.
Giant dipole resonance as a quantitative constraint on the symmetry energy
The possible constraints on the poorly determined symmetry part of the effective nuclear Hamiltonians or effective energy functionals, i.e., the so-called symmetry energy $S(\ensuremath{\rho})$, are
Microscopic Calculation and Local Approximation of the Spatial Dependence of the Pairing Field with Bare and Induced Interaction
The bare nucleon-nucleon interaction is essential for the production of pair correlations in nuclei, but an important contribution also arises from the induced interaction resulting from the exchange
Attractive and repulsive contributions of medium fluctuations to nuclear superfluidity
Oscillations of mainly surface character ($S=0$ modes) give rise, in atomic nuclei, to an attractive (induced) pairing interaction, while spin ($S=1$) modes of mainly volume character generate a
Folding and misfolding of designed proteinlike chains with mutations
The analysis reveals that mutations affect primarily the energetics of the native conformation and to a much lesser extent the ensemble of unfolded conformations, corroborating the utility of the “energy gap” concept for the analysis of folding properties of proteinlike heteropolymers.
The stability of model proteins with designed sequences is assessed in terms of the number of sequences, obtained from the designed sequence through mutations, which fold into 5 the ``native'' conformation, which shows a remarkable degree of stability and, to a large extent, of designability.
Cooper pair transfer in nuclei.
The second-order distorted wave Born approximation implementation of two-particle transfer direct reactions which includes simultaneous and successive transfer is tested with the help of controlled nuclear structure and reaction inputs against data spanning the whole mass table and showed to constitute a quantitative probe of nuclear pairing correlations.
Quasiparticle random-phase approximation with quasiparticle-vibration coupling: Application to the Gamow-Teller response of the superfluid nucleus $^{120}$Sn
We propose a self-consistent quasiparticle random-phase approximation (QRPA) plus quasiparticle-vibration coupling (QPVC) model with Skyrme interactions to describe the width and the line shape of
