# Induced Gravity in Superfluid 3He

@article{Volovik1998InducedGI, title={Induced Gravity in Superfluid 3He}, author={Grigori E. Volovik}, journal={Journal of Low Temperature Physics}, year={1998}, volume={113}, pages={667-680} }

The gapless fermionic excitations in superfluid3He-A have the “relativistic” spectrum close to the gap nodes. This allowed us to model the modern cos-mological scenaria of baryogenesis and magnetogenesis. The same massless fermions induce another low-energy property of the quantum vacuum – the gravitation. The effective metric of the space, in which the free quasiparticles move along geodesies, is not generally flat. Different order parameter textures correspond to curved effective space and…
