AI Article Synopsis
- The text discusses the phenomenon of strange metal (SM) behavior, characterized by linear resistivity at low temperatures, which is seen in strongly correlated systems, particularly in hole-doped spin-valley (SV) semiconductors like VWSe.
- The study finds that this SM behavior occurs over a broad temperature range (1.8-150 K) and is notably suppressed at temperatures below 20 K when a magnetic field is applied.
- The authors suggest that the SM behavior is linked to spin-orbit coupling and strong correlation effects, which could provide new insights into the understanding of strange metal behavior related to superconductivity and magnetism.
Article Abstract
Linear resistivity-temperature (-) at low temperatures, referred to as strange metal (SM), is an unusual characteristic observed in strongly correlated systems. SM is often mingled with superconductivity and magnetism in various materials. Here, we report a linear - relation in a hole-doped, degenerate spin-valley (SV) semiconductor, VWSe, with hole pockets in the valence band. SM emerges over a wide temperature range (1.8-150 K) without any apparent superconductivity down to 110 mK. This SM behavior is suppressed at low temperatures below 20 K in the presence of a magnetic field. The ansatz yields the γ/α ratio of ∼4, larger than the previous reports. The observed SM over a wide temperature range is explained by a spin-orbit coupling (SOC)-mediated SV pair with strong correlation effects, analogous to a phonon-mediated Cooper pair in superconductivity. This finding opens possible routes for understanding strange metal behavior through the interplay of strong SOC and strong Coulomb interactions.

Pseudogap in electron-doped cuprates: Strong correlation leading to band splitting.
Proc Natl Acad Sci U S A

The pseudogap phenomena have been a long-standing mystery of the cuprate high-temperature superconductors. The pseudogap in the electron-doped cuprates has been attributed to band folding due to antiferromagnetic (AFM) long-range order or short-range correlation. We performed an angle-resolved photoemission spectroscopy study of the electron-doped cuprates PrLaCeCuO showing spin-glass, disordered AFM behaviors, and superconductivity at low temperatures and, by measurements with fine momentum cuts, found that the gap opens on the unfolded Fermi surface rather than the AFM Brillouin zone boundary.

Xylosandrus crassiusculus Motschulsky and Xylosandrus germanus Blandford are serious ambrosia beetle pests in ornamental nurseries. Three ethanol baits, AgBio low release (LR), AgBio high release (HR), and Trécé are commercially available for use in bottle traps to determine flight activity of adult Xylosandrus spp. However, release patterns of ethanol from these baits under varying temperatures and captures of Xylosandrus spp.

In this comprehensive analysis of Chile's air quality dynamics spanning 2016 to 2021, the utilization of data from the National Air Quality Information System (SINCA) and its network of monitoring stations was undertaken. Quintero, Puchuncaví, and Coyhaique were the focal points of this study, with the primary objective being the construction of predictive models for sulfur dioxide (SO2), fine particulate matter (PM2.5), and coarse particulate matter (PM10).

Perfluorinated compounds (PFCs) are emerging environmental pollutants characterized by their extreme stability and resistance to degradation. Among them, tetrafluoromethane (CF) is the simplest and most abundant PFC in the atmosphere. However, the highest C─F bond energy and its highly symmetrical structure make it particularly challenging to decompose.
