Gapless spinons and a field-induced soliton gap in the hyperhoneycomb Cu oxalate framework compound [(${\mathrm{C}}_{2}{\mathrm{H}}_{5}{)}_{3}{\mathrm{NH}]}_{2}{\mathrm{Cu}}_{2}{({\mathrm{C}}_{2}{\mathrm{O}}_{4})}_{3}$

Frustrated magnets can be platforms for quantum spin-liquid states. A putative spin-liquid candidate, the hyperhoneycomb Cu oxalate framework compound [(C2H5)3NH]2Cu2(C2O4)3 exhibits the absence of long-range order and presence of charge-neutral excitations in the Mott insulating state at low temperatures. Here, the authors demonstrate experimental evidence for gapless spinons and a field-induced soliton gap in this material with the aid of theoretical calculations, and attribute them to weakly coupled antiferromagnetic Heisenberg chains, rather than a previously proposed spin-liquid state.

Superconductivity near spin and valley orders in graphene multilayers
Zhiyu Dong, Leonid Levitov, and Andrey V. Chubukov
Author(s): Zhiyu Dong, Leonid Levitov, and Andrey V. Chubukov

Spin excitations that soften near the onset of magnetic order have long been known to act as “paramagnon” pairing glue that can drive superconductivity. Recent findings of superconductivity in graphene bilayers and trilayers, occurring in the proximity of different itinerant ordered phases polarized…

Nonlinear dynamics of skyrmion strings
Volodymyr P. Kravchuk
Author(s): Volodymyr P. Kravchuk

The skyrmion core, percolating the volume of the magnet, forms a skyrmion string—a topological Dirac-string-like object. Here we analyze the nonlinear dynamics of a skyrmion string in a low-energy regime by means of the collective variables approach, which we generalized for the case of strings. Usi…

Charge order induced Dirac pockets in the nonsymmorphic crystal ${\mathrm{TaTe}}_{4}$
Yichen Zhang, Ruixiang Zhou, Hanlin Wu, Ji Seop Oh, Sheng Li, Jianwei Huang, Jonathan D. Denlinger, Makoto Hashimoto, Donghui Lu, Sung-Kwan Mo, Kevin F. Kelly, Robert J. Birgeneau, Bing Lv, Gang Li, and Ming Yi

The interplay between charge order (CO) and nontrivial band topology has spurred tremendous interest in understanding topological excitations beyond the single-particle description. In a quasi-one-dimensional nonsymmorphic crystal ${\mathrm{TaTe}}_{4}$, the ($2\mathrm{a}×2\mathrm{b}×3\mathrm{c}$) ch…

Funneling and spin-orbit coupling in transition metal dichalcogenide nanotubes and wrinkles
M. Daqiqshirazi and T. Brumme
Author(s): M. Daqiqshirazi and T. Brumme

Strain engineering provides a powerful means to tune the properties of two-dimensional materials. Accordingly, numerous studies have investigated the effect of bi- and uniaxial strain. Yet, the strain fields in many systems such as nanotubes and nanoscale wrinkles are intrinsically inhomogeneous and…

Large-gap quantum anomalous Hall insulators in the $A\mathrm{Ti}X$ ($A=\mathrm{K}$, Rb, Sr; $X$=Sb, Bi, Sn) class of compounds
Yadong Jiang, Huan Wang, and Jing Wang
Author(s): Yadong Jiang, Huan Wang, and Jing Wang

Quantum anomalous Hall insulators provide an intriguing platform to study emergent magnetic topological phenomena, but the low critical temperature is a weighty obstacle for practical applications. We theoretically propose that the monolayer $A\mathrm{Ti}X$ family (KTiSb, KTiBi, RbTiSb, SrTiSn) are …

Counting edge modes via dynamics of boundary spin impurities
Umar Javed, Jamir Marino, Vadim Oganesyan, and Michael Kolodrubetz
Author(s): Umar Javed, Jamir Marino, Vadim Oganesyan, and Michael Kolodrubetz

We study the dynamics of the one-dimensional Ising model in the presence of a static symmetry-breaking boundary field via the two-time autocorrelation function of the boundary spin. We find oscillatory correlations that decay as power laws. We uncover a phase diagram of dynamical responses where, up…

Fractal nodal band structures
Marcus Stålhammar and Cristiane Morais Smith
Author(s): Marcus Stålhammar and Cristiane Morais Smith

Non-Hermitian systems exhibit interesting band structures, where novel topological phenomena arise from the existence of exceptional points at which eigenvalues and eigenvectors coalesce. One important open question is how this would manifest at noninteger dimension. Here, we report on the appearanc…
