The 2H-MoTe2 films with thickness of 6–7 nm (9–10 atomic layers) were epitaxially grown on a silicon wafer (see Methods)19, then transferred onto bare grid as the free-standing (FS) specimen, and onto carbon membrane coated grid as the…

Thermodynamic analysis of magnetocaloric properties of ferromagnet undergoing structural phase transition near Curie temperature
Some solid-state compounds and alloys exhibit a magnetocaloric effect (MCE), i.e. a noticeable temperature change caused by application or removal of a magnetic field (see1 and references therein). These solids are referred to as magnetocaloric…

All genuinely entangled stabilizer subspaces are multipartite fully nonlocal
Preliminaries
Let us first provide some background information.
Stabilizer formalism
We begin with the stabilizer formalism and define the N-qubit Pauli group \({{\mathbb{P}}}_{N}\) to be one containing all N-fold tensor product of Pauli matrices

Discovery of an intermediate nematic state in a bilayer kagome metal ScV6Sn6
First, we report an intermediate phase inside the CDW state in high-quality ScV6Sn6 samples synthesized using the tin flux method10. They are nicely faceted metallic hexagonal blocks about \(1{{\rm{mm}}}\) in size with optically flat ab-plane…

Characterising high-order interdependence via entropic conjugation
Measures of multivariate interdependence
Consider a system whose state is specified by the random vector X = (X1, …, Xn) following a joint distribution pX and marginal distributions \({p}_{{X}_{i}}\). The literature presents various…

Bilateral Geiger mode avalanche in InSe Schottky photodiodes
PN Junction and Schottky Junction avalanche photodiodes
APDs are generally based on the PN or SJ junction, taking the junction’s strong electric field (εfield) under a reverse bias to trigger carrier impact ionization and multiplication….

Average quantum dynamics of closed systems over stochastic Hamiltonians
We will illustrate the general results by applying them to a few examples. The findings will then be used to gain physical insights, and the validity of the master equation approach will be examined by comparing to the exact dynamics.

Physics – Microchip Provides Made-to-Order Photons
• Physics 18, 151
A 10-µm-wide microchip can generate light with any desired direction, polarization, and intensity, which will be handy for future quantum technologies.
Bespoke photons. A laser pulse (not shown)… Continue Reading
