Kavli Affiliate: Leon Balents | First 5 Authors: Qingkai Meng, Jianting Dong, Pan Nie, Liangcai Xu, Jinhua Wang | Summary: Whenever the elastic energy of a solid depends on magnetic field, there is a magnetostrictive response. Field-linear magnetostriction implies piezomagnetism and vice versa. Here, we show that Mn$_3$Sn, a non-collinear antiferromanget with Weyl nodes, hosts […]

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Bolei Deng, Jordan R. Raney, Katia Bertoldi, Vincent Tournat, | Summary: Flexible mechanical metamaterials are compliant structures engineered to achieve unique properties via the large deformation of their components. While their static character has been studied extensively, the study of their dynamic properties is still at an […]

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Maria Teresa Mercaldo, Canio Noce, Andrea D. Caviglia, Mario Cuoco, Carmine Ortix | Summary: The Berry curvature (BC) – a quantity encoding the geometric properties of the electronic wavefunctions in a solid – is at the heart of different Hall-like transport phenomena, including the anomalous Hall […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Xingyao Chen, Shuailiang Ge, Jia Liu, Yan Luo | Summary: Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: The first billion years of cosmic history remains largely unobserved. We demonstrate, using a novel machine learning technique, how combining upper limits on the spatial fluctuations in the 21-cm signal with […]

Kavli Affiliate: Paul McEuen | First 5 Authors: Teaya Yang, David Hathcock, Yuchao Chen, Paul McEuen, James P. Sethna | Summary: We propose a novel design paradigm for multistate machines where transitions from one state to another are organized by bifurcations of multiple equilibria of the energy landscape describing the collective interactions of the machine […]
Kavli Affiliate: John Silverman | First 5 Authors: Johan Comparat, Wentao Luo, Andrea Merloni, Surhud More, Mara Salvato | Summary: Which galaxies in the general population turn into active galactic nuclei (AGNs) is a keystone of galaxy formation and evolution. Thanks to SRG/eROSITA’s contiguous 140 square degree pilot survey field, we constructed a large, complete, […]
