Chiral-bubble-induced topological Hall effect in ferromagnetic topological insulator heterostructures

January 6, 2021

Author(s)

Wenbo Wang, Yifan Zhao, Fei Wang, Matthew Daniels, Cui-Zu Chang, Jiadong Zang, Di Xiao, Weida Wu

The topological Hall effect (THE) is a transverse response of charge carriers due to emergent gauge field of non-coplanar spin textures. It has been a powerful tool to probe unconventional topological spin orders, such as the skyrmion crystal phase, in

Thermoelectric transport in coupled double layers with interlayer excitons and exciton condensation

December 29, 2020

Author(s)

Jiuning Hu, David B. Newell, Yong P. Chen, Albert Rigosi

We employ quantum Boltzmann formalism to study the transport properties of generic double layer systems where the strong interlayer interaction allows the formation of interlayer excitons and exciton condensations. The Onsager relation for Coulomb drag

A system for probing Casimir energy corrections to the condensation energy

December 28, 2020

Author(s)

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

Kitaev Interactions in the Co Honeycomb Antiferromagnets Na 3 Co 2 SbO 6 and Na 2 Co 2 TeO 6

December 24, 2020

M. Songvilay, J. Robert, Jose Rodriguez Rivera, William D. Ratcliff, F. Damay, V. Baledent, M. Jimenez-Ruiz, P. Lejay, E. Pachoud, A. Hadj-Azzem, V. Simonet, C. Stock

Co 2+ ions in an octahedral crystal field, stabilize a jeff = 1⁄2 ground state with an orbital degree of freedom and and have been recently put forward for realising Kitaev interactions, a prediction that we have tested by investigating spin dynamics in

Microscopic Origin of Inhomogeneous Transport in Four-Terminal Tellurene Devices

December 22, 2020

Author(s)

Benjamin Kupp, Gang Qiu, Yixiu Wang, Clayton Caspeer, Thomas Mitchell (Mitch) Wallis, Joanna Atkin, Wenzhuo Wu, Peide Ye, Pavel Kabos, Samuel Berweger

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
