We study the role of chiral nuclear forces on propagation neutrinos in hot neutron matter. In particular, we analyze convergence dynamical structure factor and neutrino mean free path with order power counting forces, as well regulator cutoff these determination quantities. Single-particle energies chemical potentials needed to calculate are obtained within Brueckner-Hartree-Fock approximation ...
We study fundamental morphological descriptors of disordered media (e.g., heterogeneous materials, liquids, and amorphous solids): the chord-length distribution function p(z) and the free-path distribution function p(z,a). For concreteness, we will speak in the language of heterogeneous materials composed of two different materials or “phases.” The probability density function p(z) describes th...
Heat conduction in semiconductors and dielectrics depends upon their phonon mean free paths that describe the average travelling distance between two consecutive phonon scattering events. Nondiffusive phonon transport is being exploited to extract phonon mean free path distributions. Here, we describe an implementation of a nanoscale thermal conductivity spectroscopy technique that allows for t...
Abstract The mean free path of ionizing photons, λ mfp , is a critical parameter for modeling the intergalactic medium (IGM) both during and after reionization. We present direct measurements from QSO spectra over redshift range 5 < z 6, including first at ≃ 5.3 5.6. Our sample includes data XQR-30 VLT large program, as well new Keck/ESI observations QSOs near ∼ 5.5, which we also acquire [C...
