The recent emergence of cavity-spintronics [1] has garnered intense interest from both the quantum information and spintronics communities, the former inspired by the enhanced coherence rates of ferromagnetic systems and the latter motivated by new avenues for spin current control. Indeed myriad technological developments have already been revealed, such as novel memory architectures [2],...

Les matériaux thermochromes sont ceux qui subissent un changement brusque de premier ordre de leurs propriétés optiques à une température spécifique. Un tel matériau thermochrome très connu est le VO2, il présente un intérêt scientifique et industriel majeur. En effet, les couches de VO2 sont des semi-conducteurs transparents dans l’infrarouge à une température ambiante et passent à un état...

In quantum physics, if we can find the eigenstates $| \phi_i\rangle$ of a Hamiltonian $H$, and the respective eigenergies $E_i$, we can calculate many aspects such as time evolution, or its thermal properties. Exact diagonalization is a method which can solve the Hamiltonian numerically. For a small Hamiltonian system, we can find the eigenvalues by solve the characteristic polynomial equation...

Electron beam induced current (EBIC) measurements were carried out in situ in the scanning electron microscope on free-standing GaAs/Fe core–shell nanowires (NWs), isolated from the GaAs substrate via a layer of aluminum oxide. The excess current as a function of the electron beam energy, position on the NW, and scan direction were collected, together with energy dispersive x-ray spectroscopy....

Abstract
Lithium has been investigated in detail as a possible acceptor impurity in zinc oxide for many years. Li interstitials are highly mobile in ZnO under Zn rich conditions and diffuse easily at temperatures as low as 300C. In contrast Li substituting for Zn sites is a known deep acceptor and is formed at much lower concentrations under O-rich conditions. [1]. The high mobility of Li...

Weyl metal is one of the topological non-trivial materials holding Weyl fermions which are massless and have a chirality. The Weyl metal has been described in terms of axion electromagnetism rather than in Maxwell electromagnetism, and has peculiar properties such as chiral anomaly, the presence of magnetic monopole in the reciprocal lattice space and negative longitudinal magneto resistance....

Silicon nanostructures are candidates for thermoelectric materials and can be used to effectively harvest energy if they can be designed in such a way as to improve their thermodynamic figure of merit. In silicon this is achieved primarily by reducing thermal conductivity through clever design minimizing heat transport. Phononic crystals are a form of acoustic metamaterial that aim to do this...

When can quantum information be localized to each of a collection of spacetime

regions, while also excluded from another collection of regions? We answer this question by defining and analyzing the localize-exclude task, in which a state must be localized to a collection of authorized regions while also being excluded from a set of unauthorized regions. This task is a spacetime analogue of... -

We combine optical tweezers with feedback to impose arbitrary potentials on a colloidal particle. The feedback trap detects a particle’s position, calculates a force based on an imposed \virtual potential," and shifts the trap center to generate the desired force. We create virtual harmonic and double-well potentials to manipulate particles. The harmonic potentials can be chosen to be either...

Nucleation is the process by which a bulk metastable phase undergoes a phase transition to a stable phase via the formation of a local fluctuation (the critical nucleus) of sufficient size to be able to grow spontaneously to macroscopic scale. In the case of ``two-step nucleation" (TSN), the first step in the phase transformation process consists of the appearance in the bulk metastable phase...
