Axions and superfluidity in Weyl semimetals

Author(s): Emil Mottola, Andrey V. Sadofyev, and Andreas StergiouAn effective field theory (EFT) for dynamical axions in Weyl semimetals (WSMs) is presented. A pseudoscalar axion excitation is predicted in WSMs at sufficiently low temperatures, independently of the strength of the Weyl fermion self-coupling. For strong fermion self-coupling the axion...

Topological protection of Majorana polaritons in a cavity

Author(s): Zeno Bacciconi, Gian Marcello Andolina, and Christophe MoraCavity embedding is an emerging paradigm for the control of quantum matter, offering avenues to manipulate electronic states and potentially drive topological phase transitions. In this work, we address the stability of a one-dimensional topological superconducting phase to the vacuum...

Persistent spin dynamics in magnetically ordered honeycomb-lattice cobalt oxides

Author(s): Ping Miao, Xianghong Jin, Weiliang Yao, Yue Chen, Akihiro Koda, Zhenhong Tan, Wu Xie, Wenhai Ji, Takashi Kamiyama, and Yuan LiIn the quest to find quantum spin liquids, layered cobalt oxides Na2Co2TeO6 and Na3Co2SbO6 have been proposed as promising candidates for approximating the Kitaev honeycomb-lattice model. Yet, their suitability has...

Exciton-activated effective phonon magnetic moment in monolayer ${\mathrm{MoS}}_{2}$

Author(s): Chunli Tang, Gaihua Ye, Cynthia Nnokwe, Mengqi Fang, Li Xiang, Masoud Mahjouri-Samani, Dmitry Smirnov, Eui-Hyeok Yang, Tingting Wang, Lifa Zhang, Rui He, and Wencan JinChiral phonons are lattice vibration modes in which the atomic circular motions produce nonzero angular momentum. In monolayer MoS2, the authors demonstrate here a chiral phonon...

Ultrahigh pressure shock compression of platinum up to 1.1 TPa: Melting and ionization

Author(s): Zhiguo Li, Long Hao, Xiang Wang, Guojun Li, Yong Hou, Qingsong Wang, Lei Liu, Huayun Geng, Yuying Yu, Chengda Dai, Qiang Wu, and Jianbo HuShock compression experiments on platinum (Pt) were carried out by combining a two-stage gas gun with the unique high-Z three-stage gas gun launcher technique. The shock Hugoniot of Pt was determined in...

Longitudinal coupling between electrically driven spin qubits and a resonator

Author(s): Sarath Prem, Pei-Xin Shen, Marcin M. Wysokiński, and Mircea TrifAt the core of the success of semiconducting spin qubits is the ability to manipulate them electrically, enabled by the spin-orbit interactions. However, most implementations require external magnetic fields to define the spin qubit, which in turn activate various charge-noise...
