TLDR
The special issue on Quantum transport beyond DC has two main goals: 1) to discuss the reasons why such a special issue is timely and relevant and 2) to emphasize didactic explanations in front of formal mathematical developments as mentioned in this paper.Abstract:
This introductory paper for the special issue on Quantum transport beyond DC has two main goals. First, we discuss the reasons why such a special issue is timely and relevant. Second, we present a brief summary of the subsequent papers included in it. Along the paper, we emphasize didactic explanations in front of formal mathematical developments.read more

Environmental effects in the third moment of voltage fluctuations in a tunnel junction
TL;DR: The first measurements of the third moment of the voltage fluctuations in a conductor are presented, which can provide new and complementary information on the electronic transport in conducting systems.
Journal ArticleDOI
Numerical simulations of time-resolved quantum electronics
TL;DR: In this article, the authors developed a theoretical framework for the calculation of time-resolved observables in a general multiterminal system subject to an arbitrary time-dependent perturbation (oscillating electrostatic gates, voltage pulses, time-varying magnetic fields, etc.).
Journal ArticleDOI
Numerical simulations of time resolved quantum electronics
TL;DR: In this paper, a wave function that obeys a simple Schrodinger equation with an additional source term that accounts for the electrons injected from the electrodes is proposed. And the time resolved observables (current, density) and the (inelastic) scattering matrix are simply expressed in terms of this wave function.
Journal ArticleDOI
Applied Bohmian mechanics
TL;DR: In this article, the authors present a large list of examples showing how the Bohmian formalism provides a useful solution in different forefront research fields for this kind of problems (where the Bohmanian and the quantum hydrodynamic formalisms coincide).

Time-dependent exchange and tunneling: detection at the same place of two electrons emitted simultaneously from different sources.
TL;DR: In this article, the two-particle scattering probabilities in tunneling scenarios with exchange interaction are analyzed with quasiparticle wave packets, and it is shown that the probability of detecting two (identically injected) electrons at the same side of the barrier is different from zero in very common (single or double barrier) scenarios.

Self-Consistent Equations Including Exchange and Correlation Effects
Walter Kohn,L. J. Sham +1 more
TL;DR: In this paper, the Hartree and Hartree-Fock equations are applied to a uniform electron gas, where the exchange and correlation portions of the chemical potential of the gas are used as additional effective potentials.

Inhomogeneous Electron Gas
P. C. Hohenberg,Walter Kohn +1 more
TL;DR: In this article, the ground state of an interacting electron gas in an external potential was investigated and it was proved that there exists a universal functional of the density, called F[n(mathrm{r})], independent of the potential of the electron gas.

The SIESTA method for ab initio order-N materials simulation
José M. Soler,Emilio Artacho,Julian D. Gale,Alberto García,Javier Junquera,Javier Junquera,Pablo Ordejón,Daniel Sánchez-Portal +7 more
TL;DR: In this paper, a selfconsistent density functional method using standard norm-conserving pseudopotentials and a flexible, numerical linear combination of atomic orbitals basis set, which includes multiple-zeta and polarization orbitals, was developed and implemented.
