Orbital-motion-limited theory of dust charging and plasma response / Tang, Xian-Zhu ; Delzanno, Gian Luca
The foundational theory for dusty plasmas is the dust charging theory that provides the dust potential and charge arising from the dust interaction with a plasma. The most widely used dust charging theory for negatively charged dust particles is the so-called orbital motion limited (OML) theory, which predicts the dust potential and heat collection accurately for a variety of applications, but was previously found to be incapable of evaluating the dust charge and plasma response in any situation. [...]

Sequential evacuation strategy for multiple rooms toward the same means of egress / Parisi, Daniel R ; Negri, Pablo A
This paper examines different evacuation strategies for systems where several rooms evacuate trough the same means of egress, using microscopic pedestrian simulation.As a case study, a medium-rise office building is considered. It was found that the standard strategy, whereby the simultaneous evacuation of all levels is performed, can be improved by a sequential evacuation, beginning with the lowest floor and continuing successively with each one of the upper floors after a certain delay. [...]

Ideological and Temporal Components of Network Polarization in Online Political Participatory Media / Garcia, David ; Abisheva, Adiya ; Schweighofer, Simon ; Serdült, Uwe ; Schweitzer, Frank
Political polarization is traditionally analyzed through the ideological stances of groups and parties, but it also has a behavioral component that manifests in the interactions between individuals. We present an empirical analysis of the digital traces of politicians in politnetz.ch, a Swiss online platform focused on political activity, in which politicians interact by creating support links, comments, and likes.

Adiabatic rapid passage two-photon excitation of a Rydberg atom / Kuznetsova, Elena ; Liu, Gengyuan ; Malinovskaya, Svetlana A
We considered the two-photon adiabatic rapid passage excitation of a single atom from the ground to a Rydberg state. Three schemes were analyzed: both pump and Stokes fields chirped and pulsed, only the pump field is chirped, and only the pump field is pulsed and chirped while the Stokes field is continuous wave (CW). [...]

Population inversion in hyperfine states of Rb with a single nanosecond chirped pulse in the framework of a 4-level system / Liu, G ; Zakharov, V ; Collins, T ; Gould, P ; Malinovskaya, S A
We implement a 4-level semiclassical model of a single pulse interacting with the hyperfine structure in ultracold rubidium aimed at control of population dynamics and quantum state preparation. We discuss a method based on pulse chirping to achieve population inversion between hyperfine states of the 5S shell. [...]

Radiocarbon Dioxide detection based on Cavity Ring-Down Spectroscopy and a Quantum Cascade Laser / Genoud, Guillaume ; Vainio, Markku ; Phillips, Hilary ; Dean, Julian ; Merimaa, Mikko
Monitoring of radiocarbon ($^{14}$C) in carbon dioxide is demonstrated using mid-infrared spectroscopy and a quantum cascade laser. The measurement is based on cavity ring-down spectroscopy, and a high sensitivity is achieved with a simple setup. [...]

Bosonic and fermionic Weinberg-Joos (j,0)+ (0,j) states of arbitrary spins as Lorentz-tensors or tensor-spinors and second order theory / Acosta, E G Delgado ; Guzman, V M Banda ; Kirchbach, M
We propose a general method for the description of arbitrary single spin-j states transforming according to (j,0)+(0,j) carrier spaces of the Lorentz algebra in terms of Lorentz-tensors for bosons, and tensor-spinors for fermions, and by means of second order Lagrangians. The method allows to avoid the cumbersome matrix calculus and higher \partial^{2j} order wave equations inherent to the Weinberg-Joos approach. [...]

The Eisenhart lift: a didactical introduction of modern geometrical concepts from Hamiltonian dynamics / Cariglia, Marco ; Alves, Filipe Kelmer
This work originates from part of a final year undergraduate research project on the Eisenhart lift for Hamiltonian systems. The Eisenhart lift is a procedure to describe trajectories of a classical natural Hamiltonian system as geodesics in an enlarged space. [...]
