A superfluid helium system for an LST IR experiment [PDF]

The results are presented of a study program directed toward evaluating the problems associated with cooling an LST instrument to 2 K for a year by using superfluid helium as the cooling means. The results include the parametric analysis of systems using

Observation of Topological Chirality Switching Induced Freezing of a Skyrmion Crystal

Advanced Materials, EarlyView.
Using Lorentz Transmission electron microscopy, it is shown that in the insulating van der Waals ferromagnet, CrBr3, a magnetic field can cause Bloch skyrmionic bubbles to spontaneously switch their chirality. As achiral type‐II bubbles are an intermediate state, the bubbles rapidly elongate and shrink when switching, thereby inducing a freezing of the

Quantum Phase Transitions in Graphene Coupled to a Twisted WSe2 Moiré Ferroelectricity

Advanced Materials, EarlyView.
Moiré ferroelectricity in twisted WSe2 (t‐WSe2) breaks graphene's sublattice symmetry, inducing a room‐temperature metal‐insulator transition. Coupling graphene with ferroelectric domains of t‐WSe2 creates local Dirac points and metallic phases with Fermi‐liquid and non‐Fermi‐liquid behavior.

Investigating the Effects of Atomic Oxygen Cold Plasma Surface Cleaning on the Oil Paint

Advanced Materials Interfaces, EarlyView.
This study investigates a novel cleaning technique based on the use of atomic oxygen (AO) generated in atmospheric pressure plasma, with the focus on the systematic investigation of the impact of AO on sensitive organic substrates during the cleaning action, to explore the applicability and limitations of the technique.
