Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
Contributions to Plasma Physics, EarlyView.ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Precision control for gravitational wave detectors
, 2022 Gravitational Wave (GW) detectors are state-of-the-art mechatronic systems that can measure spatial distortions in the order of 10"18 meters. Two GW detectors that are currently operational are LIGO and Virgo, both of which have already measured GWs, with the first one being measured in 2015 resulting from the collision of two black holes.

Few‐Photon Fluorescence From Ultracold Bosons in an Optical Cavity
Contributions to Plasma Physics, EarlyView.ABSTRACT Within a cavity quantum electrodynamics framework, we analyse the fluorescent spectrum of ultracold bosons in resonant and second‐harmonic generation (SHG) regimes. Two settings are considered: (i) (few) bosons in an optical lattice and (ii) a trapped two‐component dilute Bose–Einstein condensate (2BEC) within the Bogoliubov scheme.

Deep Underground Science and Engineering, EarlyView.The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Gravitational lenses as long-baseline gravitational-wave detectors [PDF]
Physical Review Letters, 1989 Gravitational waves produce a time delay between the different images of a gravitational lens. The measurements of the time delay in the gravitational lens 0957{plus minus}561 put new limits on the amplitude of low-frequency gravitational waves {ital h}{lt}2{times}10{sup {minus}5}({nu}/(3{times}10{sup {minus}18} Hz)) in the frequency range 3{times}10 ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Disasters exacerbated by climate change have prompted adaptation measures, including seawall heightening, which is an effective approach to protecting coastal areas. However, the combined effect of rising sea levels and tsunamis can create a compound coastal hazard, in which long‐term sea level rise amplifies the impact of tsunamis.
