Electron relaxation in metals: Theory and exact analytical solutions [PDF]

open access: yes, 2008
The non-equilibrium dynamics of electrons is of a great experimental and theoretical value providing important microscopic parameters of the Coulomb and electron-phonon interactions in metals and other cold plasmas. Because of the mathematical complexity

HOL Light QE

open access: yes, 2018
We are interested in algorithms that manipulate mathematical expressions in mathematically meaningful ways. Expressions are syntactic, but most logics do not allow one to discuss syntax. ${\rm CTT}_{\rm qe}$ is a version of Church's type theory that includes quotation and evaluation operators, akin to quote and eval in the Lisp programming language ...

Axial F–Bi–Ov Electron Pump Drives Continuous Reconfiguration of Bi Sites for Efficient Photocatalytic N2 Reduction

open access: yesAdvanced Science, EarlyView.
Axial Fluorine and Light‐Induced Oxygen Vacancies Synergize as an Electron Pump to Lower N2 Activation Energy and Enable Sustained NH3 Synthesis on FBWO. ABSTRACT The electronic structure precision of single‐atom catalysts (SACs) represents a decisive factor limiting advancements in photocatalytic nitrogen reduction (NRR) efficiency.

Numerical Study of Carrier Multiplication Pathways in Nanocrystalline and Bulk Form of PbSe

open access: yes, 2011
Employing the interband exciton scattering model, we have performed a numerical study of the direct photogeneration and population relaxation processes contributing to carrier multiplication (CM) in nanocrystalline and bulk PbSe.

DC‐magnetometry Analytical Tool Driven by Spin Ordering Phenomena for Sensing Chemical Interactions at the Surface of Nanomaterials

open access: yesAdvanced Science, EarlyView.
The adsorption of AsV on akaganeite nanorods was found to provide a magnetic signature. A change in the surface spin order gave rise to a second peak in the zero‐field cooled curve. AsIII adsorption does not provide any change in the magnetic behavior of the sorbent.

A Multi-objective Optimization Model for Robust Skip-Stop Scheduling with Earliness and Tardiness Penalties

open access: yesUrban Rail Transit, 2019
Inefficient transport systems impose extra travel time for travelers, cause dissatisfaction and reduce service levels. In this study, the demand-oriented train scheduling problem is addressed using a robust skip-stop method under uncertain arrival rates ...

Resolving the Axial Mass Anomaly in neutrino Scattering

open access: yes, 2011
We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum transfer (Q2) in terms of a correction to the magnetic ...
