Search for low-mass electron-recoil dark matter using a single-charge sensitive SuperCDMS-HVeV Detector

Posted by klaurent Stanford

Kavli Affiliate: D. B. Macfarlane | Summary:We present constraints on low-mass dark matter electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water equivalent. The experiment benefits from the minimizing of luminescence from the […]

The clustering of C IV and Si IV at the end of reionisation: A perspective from the E-XQR-30 survey

Posted by klaurent Cambridge

Kavli Affiliate: Martin Haehnelt | Summary:We aim to study the clustering of metal absorption lines and the structures that they arise in as a function of cosmic time. We focus on C IV and Si IV absorption features that are identified along a given quasar sightline. We exploit the two-point correlation function (2PCF) to investigate […]

Electronic origin of delicate antiferromagnetism in Fe$_x$NbS$_2$

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey Neaton | Summary:Among the family of intercalated transition-metal dichalcogenides (TMDs), Fe$_x$NbS$_2$ is found to possess unique current-induced resistive switching behaviors, tunable antiferromagnetic states, and a commensurate charge order, all of which are tied to a critical Fe doping of $x_c$ = 1/3. However, the electronic origin of such extreme stoichiometry sensitivities remains […]

Deconfined Quantum Critical Point in Quantum Hall Bilayers

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Guangyu Yu, Guangyu Yu, , , | Summary: Deconfined quantum critical points (DQCPs) represent an unconventional class of quantum criticality beyond the Landau-Ginzburg-Wilson-Fisher paradigm. Nevertheless, both their theoretical identification and experimental realization remain challenging. Here we report compelling evidence of a DQCP in quantum Hall bilayers with […]

Octupole-driven spin-transfer torque switching of all-antiferromagnetic tunnel junctions

Posted by klaurent Cornell

Kavli Affiliate: Gregory D. Fuchs | Summary:Magnetic tunnel junctions (MTJs) based on ferromagnets are canonical devices in spintronics, with wide-ranging applications in data storage, computing, and sensing. They simultaneously exhibit mechanisms for electrical detection of magnetic order through the tunneling magnetoresistance (TMR) effect, and reciprocally, for controlling magnetic order by electric currents through spin-transfer torque […]
