Phase transitions of wave packet dynamics in disordered non-Hermitian systems

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Fabian A. Gerritsma, Ion Cosma Fulga, Anton R. Akhmerov | Summary: Disorder can localize the eigenstates of one-dimensional non-Hermitian systems, leading to an Anderson transition with a critical exponent of 1. We show that, due to the lack of energy conservation, the […]

Mineral Detection of Neutrinos and Dark Matter. A Whitepaper

Kavli Affiliate: Noah A. Kurinsky | First 5 Authors: Sebastian Baum, Patrick Stengel, Natsue Abe, Javier F. Acevedo, Gabriela R. Araujo | Summary: Minerals are solid state nuclear track detectors – nuclear recoils in a mineral leave latent damage to the crystal structure. Depending on the mineral and its temperature, the damage features are retained […]

Magnetostriction, piezomagnetism and domain nucleation in a kagome antiferromagnet

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 […]

Nonlinear waves in flexible mechanical metamaterials

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 […]

Orbital design of Berry curvature: pinch points and giant dipoles induced by crystal fields

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 […]

Searching for Ultralight Dark Matter Conversion in Solar Corona using Low Frequency Array Data

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 […]

Joint analysis constraints on the physics of the first galaxies with low frequency radio astronomy data

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 […]
