Transport-Noise Witnesses of Electronic Multipartite Entanglement
Shuhan Ding, Prakash Sharma, Zecheng Shen +3
Entanglement among particles is a defining feature of strongly correlated quantum materials, distinguishing them from conventional metals and semiconductors. The ability to certify…
Fluctuation-Driven Enhancement of Spin-Orbit Torque near the Curie Temperature of Ultrathin Ferromagnets
Mateusz Szurek, Sergei Ivanov, Sergei Urazhdin
We investigate how magnetic fluctuations influence spin-orbit torque in ultrathin-film magnetic heterostructures whose Curie temperature is suppressed by confinement. Above $…
Symmetries of electron interactions in Hubbard models of unconventional superconductors
Sergei Urazhdin, Yiou Zhang
We use symmetry arguments to show that the matrix elements of electron-electron interaction on a lattice reach extrema in states composed of wavevectors near high-symmetry points o…
The role of electron interactions in a failed insulator revealed by shot noise
Mateusz Szurek, Hanqiao Cheng, Zilu Pang +2
In materials known as failed insulators, electrical resistivity increases as temperature decreases, yet does not diverge - a phenomenon inconsistent with single-particle theories.…
Evidence for Bose liquid from anomalous shot noise in nanojunctions of bad metal beta-Ta
Yiou Zhang, Chendi Xie, John Bacsa +2
We report anomalous shot noise in nanojunctions of beta-tantalum, a ``bad" metal whose electronic properties are inconsistent with the Fermi liquid theory. Fano factors cluster aro…
Anomalous shot noise in a bad metal beta-tantalum
M. Szurek, H. Cheng, Z. Pang +3
We investigate the electronic shot noise produced by nanowires of -Ta, an archetypal ``bad" metal with resistivity near the Ioffe-Regel localization limit. The Fano factor chara…
Symmetry constraints on the orbital transport in solids
S. Urazhdin
We show that electron interaction with the crystal lattice imposes stringent symmetry constrains on the orbital moment propagation. We present examples that elucidate the underlyin…
Brillouin Light Scattering of Spin Waves Inaccessible with Free-Space Light
R. Freeman, R. Lemasters, T. Kalejaiye +8
Micro-focus Brillouin light scattering is a powerful technique for the spectroscopic and spatial characterization of elementary excitations in materials. However, the small momentu…
Direct observation and imaging of a spin-wave soliton with like symmetry
S. Bonetti, R. Kukreja, Z. Chen +12
The prediction and realization of magnetic excitations driven by electrical currents via the spin transfer torque effect, enables novel magnetic nano-devices where spin-waves can b…
