Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids

Advanced Materials, EarlyView.
Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

Jet outbursts, non-thermal pressure, and the AGN jet duty cycle

Monthly Notices of the Royal Astronomical Society
ABSTRACT We predict the non-thermal pressure (NTP) induced in the cores of galaxy clusters by kinetic jet feedback from an active galactic nucleus (AGN). We model a population of Fanaroff–Riley type I jets when sampling power-law distributions in jet power and age, which we evolve in time with a two-phase jet-lobe model.
