Author(s): Sebastián A. Díaz, Jonas Nothhelfer, Kjetil M. D. Hals, and Karin Everschor-SitteVortices are pointlike topological defects in superconductors whose motion dictates superconducting properties and controls device performance. In superconductor-ferromagnet heterostructures, vortices interact with topological defects in the ferromagnet such...
Author(s): Changqing Zhu, Patrick Pilch, Renato M. A. Dantas, Anneke Reinold, Yunkun Yang, Faxian Xiu, Amilcar Bedoya-Pinto, Stuart S. P. Parkin, Roderich Moessner, and Zhe WangHarmonic generation provides an efficient tool for the study of ultrafast nonlinear dynamics. We report on time-resolved optical-pump terahertz harmonic generation spectroscopic...
Author(s): Han Yan (闫寒), Owen Benton, Andriy H. Nevidomskyy, and Roderich MoessnerThe hallmark of highly frustrated systems is the presence of many states close in energy to the ground state. Fluctuations between these states can preclude the emergence of any form of order and lead to the appearance of spin liquids. Even on the classical level, spin...
Author(s): Xiangshang Xiao, Kunlong Zhao, Yifan Cui, Hanjun Liu, Yi Wei, Shuting Yang, and Amitesh PaulWe explore the exchange bias coupling at the RE-RE interfaces (RE denotes rare earth) due to a plausible increase in the spin-imbalance induced by magnetic sublattice disorder around the temperature range where one of the REs exists in its conical...
Author(s): Yaoyao Ji, Shilin Hu, Junhua Liu, Long Wei, Chen Luo, Victor Ukleev, Florin Radu, Wensheng Yan, Dachuan Chen, Zhicheng Zhong, Yulin Gan, Kai Chen, and Zhaoliang LiaoThe perovskite oxide heterointerface is a complex and fascinating region where charge transfer dramatically alters the coupling between charge, spin, orbital, and lattice order,...
Author(s): Jonas Beck, Jonathan Bodky, Johannes Motruk, Tobias Müller, Ronny Thomale, and Pratyay GhoshWe microscopically analyze the nearest-neighbor Heisenberg model on the maple leaf lattice through neural quantum state (NQS) and infinite density matrix renormalization group (iDMRG) methods. Embarking to parameter regimes beyond the exact dimer singlet...
