Greenwashing in the Spotlight: Synthesising Evidence on Unethical Environmental Claims and Future Pathways

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Firms are experiencing mounting pressure to report their environmental impact. Rather than disclosing their actual performance, however, some are engaging in unethical business (i.e., greenwashing) practices. Prior studies have contributed significantly to the greenwashing literature from varied perspectives, but a comprehensive understanding ...

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

Contributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Reweighting Scheme for the Calculation of Grand‐Canonical Expectation Values in Quantum Monte Carlo Simulations With a Fermion Sign Problem

Contributions to Plasma Physics, EarlyView.
ABSTRACT Ab initio path integral Monte Carlo (PIMC) simulations constitute the gold standard for the estimation of a broad range of equilibrium properties of a host of interacting quantum many‐body systems spanning a broad range of conditions from ultracold atoms to warm dense quantum plasmas.

Edge Fluid Turbulence Simulations of Stellarators With GRILLIX

Contributions to Plasma Physics, EarlyView.
ABSTRACT The edge fluid turbulence code GRILLIX has recently been extended from axisymmetric tokamak geometries to support 3D stellarator configurations. Following successful proof‐of‐principle simulations published in Stegmeir et al., we present here a comprehensive simulation of the Wendelstein 7‐AS stellarator.

Evidence of Free‐Bound Transitions in Warm Dense Matter and Their Impact on Equation‐of‐State Measurements

Contributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is now routinely created and probed in laboratories around the world, providing unprecedented insights into conditions achieved in stellar atmospheres, planetary interiors, and inertial confinement fusion experiments.
