Interplay of Dzyaloshinskii-Moriya and Kitaev interactions for magnonic properties of Heisenberg-Kitaev honeycomb ferromagnets

Author(s): Li-Chuan Zhang, Fengfeng Zhu, Dongwook Go, Fabian R. Lux, Flaviano José dos Santos, Samir Lounis, Yixi Su, Stefan Blügel, and Yuriy MokrousovThe properties of Kitaev materials are attracting ever increasing attention owing to their exotic properties. In realistic two-dimensional materials, the Kitaev interaction is often accompanied by the...

Electron-electron interactions and weak antilocalization in few-layer $\mathrm{Zr}{\mathrm{Te}}_{5}$ devices

Author(s): Zhijian Xie, Xinjian Wei, Shimin Cao, Yu Zhang, Shili Yan, G. D. Gu, Qiang Li, and Jian-Hao ChenMuch effort has been devoted to the electronic properties of relatively thick ZrTe5 crystals, focusing on their three-dimensional topological effects. Thin ZrTe5 crystals, on the other hand, were much less explored experimentally. Here we present...

Boundary conditions for the Néel order parameter in a chiral antiferromagnetic slab

Author(s): Oleksandr V. Pylypovskyi, Artem V. Tomilo, Denis D. Sheka, Jürgen Fassbender, and Denys MakarovUnderstanding of the interaction of antiferromagnetic solitons including domain walls and skyrmions with boundaries of chiral antiferromagnetic slabs is important for the design of prospective antiferromagnetic spintronic devices. Here, we derive...

Crystal, local atomic, and local electronic structures of ${\mathrm{YbFe}}_{2}{\mathrm{Zn}}_{20−x}{\mathrm{Cd}}_{x}\phantom{\rule{0.16em}{0ex}}(0≤x≤1.4)$: A multiband system with possible coexistence of light and heavy fermions

Author(s): A. Fahl, R. Grossi, D. Rigitano, M. Cabrera-Baez, M. A. Avila, C. Adriano, and E. GranadoThe partial (up to 7%) substitution of Cd for Zn in the Yb-based heavy-fermion material YbFe2Zn20 is known to induce a slight (∼20%) reduction of the Sommerfeld specific-heat coefficient γ and a huge (up to two orders of magnitude) reduction of the T2...

Spin pumping in superconductor-antiferromagnetic insulator bilayers

Author(s): Eirik Holm Fyhn and Jacob LinderWe study theoretically spin pumping in bilayers consisting of superconductors (SC) and antiferromagnetic insulators (AFI). We consider both compensated and uncompensated interfaces and include both the regular scattering channel and the Umklapp scattering channel. We find that at temperatures close ...[Phys....

<i>Ab initio</i> thermoelectric calculations of ring-shaped bands in two-dimensional ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3},\phantom{\rule{0.28em}{0ex}}{\mathrm{Bi}}_{2}{\mathrm{Se}}_{3}$, and ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{3}$: Comparison of scattering approximations

Author(s): Cameron Rudderham and Jesse MaassenMaterials with ring-shaped electronic bands are promising thermoelectric (TE) candidates since their unusual dispersion shape is predicted to give large power factors. In this paper, we use density functional theory to investigate single and double quintuple-layer Bi2Te3,Bi2Se3, and Sb2Te3 and to co...[Phys....

Miscibility gap and possible intrinsic Griffiths phase in $\mathrm{Sr}{({\mathrm{Fe}}_{1−x}{\mathrm{Mn}}_{x})}_{2}{\mathrm{As}}_{2}$ crystals grown by transition metal arsenide flux

Author(s): Long Chen, Cheng Cao, Hongxiang Chen, Jiangang Guo, Jie Ma, Jiangping Hu, and Gang WangThe crystal structure, magnetic, electronic, and thermal properties of Sr(Fe1−xMnx)2As2 crystals grown by transition metal arsenide flux have been systematically investigated. A miscibility gap with x ranging from 0.4362(4) to 0.9612(9) is found in the...

Quantum Monte Carlo simulation of BEC-impurity tunneling

Author(s): A. S. Popova, V. V. Tiunova, and A. N. RubtsovPolaron tunneling is a prominent example of a problem characterized by different energy scales, for which the standard quantum Monte Carlo methods face a slowdown problem. We propose a quantum-tunneling Monte Carlo (QTMC) method which is free from this issue and can be used for a wide range of...

Transient heat transfer of superfluid $^{4}\mathrm{He}$ in nonhomogeneous geometries: Second sound, rarefaction, and thermal layer

Author(s): Shiran Bao and Wei GuoTransient heat transfer in superfluid He4 (He II) is a complex process that involves the interplay of the unique counterflow heat-transfer mode, the emission of second-sound waves, and the creation of quantized vortices. Many past researches focused on homogeneous heat transfer of He II in a uniform...[Phys. Rev. B 103,...

Universal collective modes from strong electronic correlations: Modified $1/{\mathcal{N}}_{f}$ theory with application to high-${T}_{c}$ cuprates

Author(s): Maciej Fidrysiak and Józef SpałekA nonzero-temperature technique for strongly correlated electron lattice systems, combining elements of both variational wave function (VWF) approach and expansion in the inverse number of fermionic flavors (1/Nf), is developed. The departure point, VWF method, goes beyond the renormalized mean-fiel...[Phys....
