Reentrant resistivity due to the interplay of superconductivity and magnetism in ${\mathrm{Eu}}_{0.73}{\mathrm{Ca}}_{0.27}$$({\mathrm{Fe}}_{0.87}{\mathrm{Co}}_{0.13}{)}_{2}{\mathrm{As}}_{2}$
Lan Maria Tran, Andrzej J. Zaleski, and Zbigniew Bukowski
Author(s): Lan Maria Tran, Andrzej J. Zaleski, and Zbigniew Bukowski

By simultaneous Co and Ca doping we were able to obtain an ${\mathrm{EuFe}}_{2}{\mathrm{As}}_{2}$-based compound with superconductivity appearing above the antiferromagnetic order of ${\mathrm{Eu}}^{2+}$ magnetic moments. However, as soon as the antiferromagnetic order appears, a reentrance behavior…

Gilbert damping in metallic ferromagnets from Schwinger-Keldysh field theory: Intrinsically nonlocal, nonuniform, and made anisotropic by spin-orbit coupling
Felipe Reyes-Osorio and Branislav K. Nikolić
Author(s): Felipe Reyes-Osorio and Branislav K. Nikolić

Understanding the origin of damping mechanisms in the magnetization dynamics of metallic ferromagnets is a fundamental problem for nonequilibrium many-body physics of systems in which quantum conduction electrons interact with localized spins assumed to be governed by the classical Landau-Lifshitz-G…

Here we report recent data on the phenomenon of total nonreflection of spin waves (NRSWs). Using space- and phase-resolved Brillouin light scattering we experimentally studied the amplitude, direction, and phase of the NRSW in yttrium iron garnet films with artificial defects—an antidot array. An NR…

Phase transitions in the Haldane-Hubbard model
Wan-Xiu He, Rubem Mondaini, Hong-Gang Luo, Xiaoqun Wang, and Shijie Hu
Author(s): Wan-Xiu He, Rubem Mondaini, Hong-Gang Luo, Xiaoqun Wang, and Shijie Hu

The Haldane-Hubbard model is a prime example of the combined effects of band topology and electronic interaction. We revisit its spinful phase diagram at half filling as a consensus on the presence of SU(2) symmetry is currently lacking. To start, we utilize the Hartree-Fock mean-field method, which…

Quasiparticle interference of the topological surface state on gray arsenic

Author(s): Xingfu Cai, Zhongzheng Yang, Chenhaoping Wen, Yang Yang, Xiangde Zhu, Wei Ning, Shichao Yan, and Jiamin Xue

Recent theory and experiment have shown that gray arsenic has a Shockley surface state with a topological origin, and is spin polarized by the Rashba spin-orbital coupling. However, there has been no microscopic study of the scattering properties of this surface state, which could reveal its spin st…

Minimal quantum dot based Kitaev chain with only local superconducting proximity effect
William Samuelson, Viktor Svensson, and Martin Leijnse
Author(s): William Samuelson, Viktor Svensson, and Martin Leijnse

The possibility to engineer a Kitaev chain in quantum dots coupled via superconductors has recently emerged as a promising path toward topological superconductivity and possibly non-Abelian physics. Here we show that it is possible to avoid some of the main experimental hurdles on this path by using…

Definition and classification of Fermi surface anomalies
Da-Chuan Lu, Juven Wang, and Yi-Zhuang You
Author(s): Da-Chuan Lu, Juven Wang, and Yi-Zhuang You

We propose that the Fermi surface anomaly of symmetry group $G$ in any dimension is universally classified by $G$-symmetric interacting fermionic symmetry-protected topological (SPT) phases in $(0+1)$-dimensional spacetime. The argument is based on the perspective that the gapless fermions on the Fe…

Author(s): Lingpu Gong, Yan Li, Huaiqiang Wang, and Haijun Zhang

Recently, the magnetic topological insulator ${\mathrm{MnBi}}_{2}{\mathrm{Te}}_{4}$ was discovered as a great platform to investigate the interplay between magnetism and topology, such as the anomalous Hall effect and the topological magnetoelectric effect. Here, we employ a first-principles approac…

Spin Weyl topological insulators
Rafael González-Hernández and Bernardo Uribe
Author(s): Rafael González-Hernández and Bernardo Uribe

The quantum nature of electron spin is crucial for establishing topological invariants in real materials. Since the spin does not in general commute with the Hamiltonian, some of the topological features of the material can be extracted from its study. In insulating materials, the spin operator indu…

Poles and zeros in non-Hermitian systems: Application to photonics
Felix Binkowski, Fridtjof Betz, Rémi Colom, Patrice Genevet, and Sven Burger
Author(s): Felix Binkowski, Fridtjof Betz, Rémi Colom, Patrice Genevet, and Sven Burger

Resonances are essential for understanding the interactions between light and matter in photonic systems. The real frequency response of the non-Hermitian systems depends on the complex-valued resonance frequencies, which are the poles of electromagnetic response functions. The zeros of the response…

Impact of vacancies on twisted bilayer graphene quantum point contacts
Pablo Moles, Francisco Domínguez-Adame, and Leonor Chico
Author(s): Pablo Moles, Francisco Domínguez-Adame, and Leonor Chico

We carry out an extensive numerical study of low-temperature electronic transport in quantum point contacts based on twisted bilayer graphene. Assuming ballistic electron dynamics, quantized plateaus in the conductance are observed in defect-free samples when the twisting angle is large enough. Howe…

Author(s): Giuseppe Baio, Matthew T. Wheeler, David S. Hall, Janne Ruostekoski, and Magnus O. Borgh

We systematically and analytically construct a set of spinor wave functions representing defects and textures that continuously penetrate interfaces between coexisting, topologically distinct magnetic phases in a spin-2 Bose-Einstein condensate. These include singular and nonsingular vortices carryi…

We investigate the dependence of the photogalvanic response of a twofold degenerate multi-Weyl semimetal on its topological charge, tilt, and chemical potential. We derive analytical expressions for the shift and injection conductivities for tilted charge-$n$ Weyl points using a low-energy two-band …

Topological high-harmonic spectroscopy
Carlos Hernández-García

Communications Physics, Published online: 11 January 2024; doi:10.1038/s42005-023-01511-7

Harmonics produced when structured lasers hit isotropic targets inherit the topological properties of the driver, but such properties become more complex in the case of anisotropic nonlinear targets. The authors exploit topological analysis of the high-order harmonics to spatially resolve the information about the nonlinear response of the target.
