Strengthening weak measurements of qubit out-of-time-order correlators [PDF]

open access: yes, 2018
For systems of controllable qubits, we provide a method for experimentally obtaining a useful class of multitime correlators using sequential generalized measurements of arbitrary strength.

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Increasing tolerance of wolves in Montana, United States (2012–2023)

open access: yesConservation Science and Practice, Volume 8, Issue 2, February 2026.
There is little reliable human dimensions data on people's attitudes toward wolves in the Northern Rocky Mountains despite global interest in wolf management in the area, and limited information globally about how people's attitudes toward wolves change over time.

Optical Properties of Heavy Fermion Systems with SDW Order

open access: yes, 2001
The dynamical conductivity $\sigma (\omega)$, reflectivity $R(\omega)$, and tunneling density of states $N(\omega)$ of strongly correlated systems (like heavy fermions) with a spin-density wave (SDW) magnetic order are studied as a function of impurity ...

Optical signatures of the superconducting Goldstone mode in granular aluminum: experiments and theory [PDF]

open access: yes, 2017
Recent advances in the experimental growth and control of disordered thin films, heterostructures, and interfaces provide a fertile ground for the observation and characterisation of the collective superconducting excitations emerging below $T_c$ after ...

Vielseitiger und selektiver Biomolekül‐Pulldown mit kombinatorischen DNA‐quervernetzten Polymeren

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Wir stellen ein programmierbares Polymersystem für die universelle, sequenzselektive Bioseparation unter nativen Bedingungen vor. Eine Polymerphasentrennung wird durch kombinatorische DNA‐Vernetzung erreicht, wodurch DNA, RNA oder Proteine in homogener Lösung mit hoher Pulldown‐Effizienz und vernachlässigbarer Hintergrundbindung eingefangen werden ...

Linear-in-frequency optical conductivity in GdPtBi due to transitions near the triple points

open access: yes, 2018
The complex optical conductivity of the half-Heusler compound GdPtBi is measured in a frequency range from 20 to 22 000 cm$^{-1}$ (2.5 meV - 2.73 eV) at temperatures down to 10 K in zero magnetic field. We find the real part of the conductivity, $\sigma_{
