Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Xiaoxi Huang, Xiaoxi Huang, , , | Summary: We report measurements of the current-induced spin torque produced by the delafossite antiferromagnet PdCrO2 and acting on an adjacent ferromagnetic permalloy layer. The spin torque increases strongly as the temperature is reduced through the Neel temperature, when the […]
Kavli Affiliate: Amal El-Ghazaly | Summary:We report measurements of the current-induced spin torque produced by the delafossite antiferromagnet PdCrO2 and acting on an adjacent ferromagnetic permalloy layer. The spin torque increases strongly as the temperature is reduced through the Neel temperature, when the PdCrO2 transitions from a paramagnetic phase to a noncollinear antiferromagnetic state. This […]
Kavli Affiliate: Nicole A. Benedek | Summary:We present a technique for partitioning the total energy from a semi-local density functional theory calculation into contributions from individual electronic states in a localized Wannier basis. We use our technique to reveal the key role played by the $s$ and $p$ orbitals of the apical oxygen atoms in […]
Kavli Affiliate: Itai Cohen | Summary:Tuning shear thickening behavior is a longstanding problem in the field of dense suspensions. Acoustic perturbations offer a convenient way to control shear thickening in real time, opening the door to a new class of smart materials. However, complete control over shear thickening requires a quantitative description for how suspension […]
Kavli Affiliate: J. C. Seamus Davis | Summary:The kagome lattice of spin-1/2 Cu atoms in herbertsmithite (ZnCu3(OH)6Cl2) may sustain a quantum spin liquid (QSL) state with spinon quasiparticles. Each kagome plane is separated from its homologues by a layer of spinless Zn atoms. Providentially, however, some spin-1/2 Cu atoms substitute randomly onto these inter-kagome Zn […]
Kavli Affiliate: J. C. Seamus Davis | Summary:The kagome lattice of spin-1/2 copper atoms in herbertsmithite is conjectured to sustain a quantum spin liquid state with spinon quasiparticles. Ideally, the kagome crystal planes are each separated by a plane of spinless zinc atoms. However, in real crystals some spin-1/2 copper atoms substitute randomly onto these […]
Kavli Affiliate: Grace Xing | Summary:The importance of electrical contact resistance and thermal boundary resistance has increased dramatically as devices are scaled to atomic limits. The use of a rich range of materials with various bandstructures (e.g. parabolic, conical), and in geometries exploiting various dimensionalities (e.g. 1D wires, 2D sheets, and 3D bulk) will increase […]
Kavli Affiliate: Chris Xu| First 5 Authors: Jilei Xu, Jilei Xu, , , | Summary:Over 25,600 3-inch photomultiplier tubes (PMTs) have been instrumented for the central detector of the Jiangmen Underground Neutrino Observatory. Each PMT is equipped with a high-voltage divider and a frontend cable with waterproof sealing. Groups of sixteen PMTs are connected to […]
Kavli Affiliate: Brad Ramshaw | Summary:The thermal Hall effect has been observed in a wide variety of magnetic insulators, yet its origin remains controversial. While some studies attribute it to intrinsic origins — such as heat carriers with Berry curvature — others propose extrinsic origins — such as heat carriers scattering off crystal defects. Even […]
