Author(s): Erik G. C. P. van Loon and Hugo U. R. StrandDynamical mean-field theory describes the impact of strong local correlation effects in many-electron systems. While the single-particle spectral function is directly obtained within the formalism, two-particle susceptibilities can also be obtained by solving the Bethe-Salpeter equation. The solutio…...
Author(s): Z. Z. Alisultanov and A. KudlisWe examine the impact of nonmagnetic disorder on the electronic states of a multilayer structure comprising layers of both topological and conventional band insulators. Employing the Burkov-Balents model with renormalized tunneling parameters, we generate phase diagrams correlating with disorder, de… [Phys....
Author(s): Jean-Emile Bourgine and Yutaka MatsuoA model of the non-Abelian fractional quantum Hall effect is obtained from the diagonalization of the matrix model proposed by Dorey, Tong, and Turner (DTT). The Hamiltonian is reminiscent of a spin Calogero-Moser model but involves higher-order symmetric representations of the non-Abelian symmetry.… [Phys....
Author(s): Zhengde Xu, Xue Zhang, Yixiao Qiao, Gengchiau Liang, Shuyuan Shi, and Zhifeng ZhuPrevious research has demonstrated the spin-orbit torque (SOT) switching of Mn3Sn in configuration I, where the spin polarization σ resides within the kagome plane. However, this configuration has yielded several unexpected outcomes, giving rise to debates concerning...
Author(s): Xiangtian Bu, Haitao Liu, and Yuanchang LiDespite being successfully synthesized [Zhang et al., Nat. Mater. 20, 1073 (2021)], the monolayer structure of stable hexagonal TiO2 is unknown, and it is not even clear whether it can exist in a freestanding form. Through first-principles calculations, we have identified two previously uncharted...
Author(s): Johan Cedervall, Vitalii Shtender, Pascal Manuel, Vladimir Pomjakushin, Roland Mathieu, Ulrich Häussermann, and Mikael S. AnderssonUsing a combination of neutron powder diffraction and SQUID magnetometry, this work explores the impact that hydrogen (deuterium) incorporation has on the magnetic properties of NdGaDx (x=0, 0.9, and 1.6). The...
