Magneto-thermoelectric transport provides an understanding of coupled electron-hole-phonon current in topological materials and has applications in energy conversion and cooling. In this work, we investigate the effects of an external magnetic field ( 3 T)

Two-beam coupling by a hot electron nonlinearity

Jagannath Paul, Mario Miscuglio, Yaliang Gui, Volker Sorger, Jared Wahlstrand
Transparent conductive oxides such as indium tin oxide (ITO) have attracted much recent interest for their enhanced optical nonlinearity near the epsilon near zero wavelength. The nonlinearity of these materials is caused by laser heating of electrons

Xin Gui, Ryan Klein, Craig Brown, Weiwei Xie
Subtle changes in chemical bonds may result in dramatic revolutions in magnetic properties in solid state materials. MnPt 5P, a new derivative of the rare-earth-free ferromagnetic MnPt5As, was discovered and is presented in this work. MnPt 5P was

We investigate the magnetic properties of LiYbO 2, containing a three-dimensionally frustrated, diamondlike lattice via neutron scattering, magnetization, and heat capacity measurements. The stretched diamond network of Yb 3+ ions in LiYbO 2 enters a long

Field-Induced Topological Hall Effect and Double-Fan Spin Structure with a c-Axis Component in the Metallic Kagome Antiferromagnetic Compound YMn 6 Sn 6

Qi Wang, Kelly J. Neubauer, Chunruo Duan, Qiangwei Yin, Satoru Fujitsu, Hideo Hosono, Feng Ye, Rui Zhang, Songxue Chi, Kathryn L. Krycka, Hechang Lei, Pengcheng Dai
The geometrical frustration nature of the kagome lattice makes it a great host to flat electronic band, non-trivial topological properties, and novel magnetisms. Metallic kagome antiferromagnet YMn 6Sn 6 exhibits the topological Hall effect (THE) when an

A system for probing Casimir energy corrections to the condensation energy

Diego J. Perez, Alexander Stange, Richard Lally, Lawrence Barrett, Matthias Imboden, Abhishek Som, David Campbell, Vladimir Aksyuk, David Bishop
In this article, we present a nano-electromechanical system (NEMS) designed to detect changes in the Casimir Energy. The Casimir effect is a result of the appearance of quantum fluctuations in the electromagnetic vacuum. Previous experiments have used nano

Tellurene—the 2D form of elemental tellurium—provides an attractive alternative to conventional 2D semiconductors due to its high bipolar mobilities, facile solution processing, and the possibility of dopant intercalation into its 1D van der Waals lattice

Josephson Microwave Sources Applied to Quantum Information Systems
