Tunnel junction of helical edge states: Determining and controlling spin-preserving and spin-flipping processes through transconductance [PDF]
, 2014 When a constriction is realized in a 2D quantum spin Hall system, electron tunneling between helical edge states occurs via two types of channels allowed by time-reversal symmetry, namely spin-preserving ({p}) and spin-flipping ({f}) tunneling processes.

On Supra – Separation Axioms for Supra Topological Spaces
Tikrit Journal of Pure Science, 2023 Through the concepts of supra open sets and supra we introduce a new class of separation axioms and study some of their properties. We could comparative between these two items.

Two New Families of Supra-Soft Topological Spaces Defined by Separation Axioms
Mathematics, 2022 This paper contributes to the field of supra-soft topology. We introduce and investigate supra pp-soft Tj and supra pt-soft Tj-spaces (j=0,1,2,3,4). These are defined in terms of different ordinary points; they rely on partial belong and partial non ...

Neutrinos and the Highest Energy Cosmic Rays [PDF]
, 2000 Observation of Ultra High Energy Cosmic Rays (UHECR) -whose energy exceeds $10^20$eV- is still a puzzle for modern astrophysics. The transfer of more than 16 Joules to a microscopic particle can hardly be achieved, even in the most powerful cosmic ...

Effects of disorder on electron tunneling through helical edge states [PDF]
, 2014 A tunnel junction between helical edge states, realized via a constriction in a Quantum Spin Hall system, can be exploited to steer both charge and spin current into various terminals.

Another Deleuzian Resnais: l'année dernière à Marienbad as conflict between sadism and masochism [PDF]
, 2008 The Deleuzian reading of L'Année dernière à Marienbad proposed here draws less on what has become a virtually canonical concept in film studies – Deleuze's time-image – than on a much earlier work by the same author, Masochism, which treats sadism and ...

How Can Active Region Plasma Escape into the Solar Wind from below a Closed Helmet Streamer? [PDF]
, 2014 Recent studies show that active-region (AR) upflowing plasma, observed by the EUV-Imaging Spectrometer (EIS), onboard Hinode, can gain access to open field-lines and be released into the solar wind (SW) via magnetic-interchange reconnection at magnetic ...

Analytical computation of the epidemic threshold on temporal networks [PDF]
, 2015 The time variation of contacts in a networked system may fundamentally alter the properties of spreading processes and affect the condition for large-scale propagation, as encoded in the epidemic threshold.
