Local manipulation of skyrmion lattice in Fe3GaTe2 at room temperature by Shuaizhao Jin, Zhan Wang, Shouzhe Dong, Yiting Wang, Kun Han, Guangcheng Wang, Zunyi Deng, Xingan Jiang, Ying Zhang, Houbing Huang, Jiawang Hong, Xiaolei Wang, Tianlong Xia, Sang-Wook Cheong, Xueyun Wang

“…Motivated by advances in spintronic devices, extensive explorations are underway to uncover materials that host topologically protected spin textures, exemplified by skyrmions. One critical challenge involved in the potential application of skyrmions in van der Waals (vdW) materials is the attainment and manipulation of skyrmions at room temperature. …”

Generalising Holographic Superconductors by Andrea Donini, Víctor Enguita-Vileta, Fabian Esser, Veronica Sanz

“…We first unify the description of s-, p-, and d-wave superconductors in a way that can be easily promoted to higher spin. Using a semianalytical procedure to compute the superconductor properties, we are able to further generalise the geometric description of the hologram beyond the AdS-Schwarzschild Black Hole paradigm and propose a set of higher-dimensional metrics which exhibit the same universal behaviour. …”

Planetary Gearbox Vibration Signal Characteristics Analysis and Fault Diagnosis by Qiang Miao, Qinghua Zhou

“…Assuming that the gearbox and the sensor revolve inversely at the speed of planet carrier, the problem can be transformed into two easier parts: research on fixed-shaft gearbox signal model and research on influence of sensor spinning. Based on this assumption, a vibration signal model of planetary gearbox is obtained. …”

Positive energy density in topologically charged exponential wormholes and Regge–Wheeler potential by Faizuddin Ahmed, Jaydeep Goswami, Abdelmalek Bouzenada

“…Our results demonstrate that the radius of the wormhole throat is consistent with established characteristics of traversable wormholes and is free from singularities. subsequently, we study the Regge–Wheeler (RW) potential in the context of our chosen wormhole background, providing a detail analysis of its implications for spin zero scalar s-waves with multipole number $$\ell =0$$ ℓ = 0 . our analysis shows that the RW potential for spin zero scalar field is influence by the global monopole parameter and the coupling constant, which possesses dimensions inverse to that of length present in the wormhole space-time geometry. …”
