Layer-dependent optically-induced spin polarization in InSe
Jovan Nelson, Teodor K. Stanev, Dmitry Lebedev +9
Optical control of spin in semiconductors has been pioneered using nanostructures of III-V and II-VI semiconductors, but the emergence of two-dimensional van der Waals materials of…
Twisted bilayers of thin film magnetic topological insulators
Gaurav Chaudhary, Anton A. Burkov, Olle G. Heinonen
Twisted bilayer graphene (TBG) near "magic angles" has emerged as a rich platform for strongly correlated states of two-dimensional Dirac semimetals. Here we show that twisted bila…
DFT+U and Quantum Monte Carlo study of electronic and optical properties of AgNiO and AgNiCoO delafossite
Hyeondeok Shin, Panchapakesan Ganesh, Paul R. C. Kent +5
As the only semimetallic -based delafossite, AgNiO has received a great deal of attention due to both its unique semimetallicity and its antiferromagnetism in the NiO$_…
Assessing the accuracy of compound formation energies with quantum Monte Carlo
Eric B. Isaacs, Hyeondeok Shin, Abdulgani Annaberdiyev +4
Accurately predicting the formation energy of a compound, which describes its thermodynamic stability, is a key challenge in materials physics. Here, we employ many-body quantum Mo…
