Orbital torque switching of room temperature two-dimensional van der Waals ferromagnet Fe3GaTe2
Orbital torque device based on 2D-vdW ferromagnet
In 2D-vdW FM SOT heterostructures, the JS can be generated by SHMs [e.g., Pt34,35,36, Bi1.1Sb0.9Te2S137, and WTe239], and then these JS flow into 2D-vdW ferromagnets, exerting a torque that…

Higher glass transition temperatures reduce thermal stress cracking in aqueous solutions relevant to cryopreservation
Theoretical considerations
Thermal stress, though in practice a function of several interacting thermophysical phenomena (e.g. thermal diffusivity, temperature-dependent viscosity), exists due only to one: thermal expansion. In the limit of zero…

Protecting gauge symmetries in the dynamics of SU(3) lattice gauge theories
A suitable framework to study dynamics: LSH framework
As mentioned in the Introduction, we focus on a particular framework, namely the LSH framework developed for SU(2)4 and SU(3)108,109 gauge theories in 1 + 1 dimensions. The SU(2) framework has…

Non-equilibrium anti-Stokes Raman spectroscopy for investigating Higgs modes in superconductors
Raman instrument
Spontaneous Raman measurements were performed on the UT-3 Raman spectrometer (see Fig. S1)46. This triple-grated spectrometer is fully achromatic due to the use of reflective optics. Excellent stray light rejection is achieved…
