Epsilon-near-zero regime enables permanent ultrafast all-optical reversal of ferroelectric polarization

Posted by in category: futurism

Researchers reveal that naturally emerging epsilon-near-zero conditions in BaTiO3 can be exploited to drive permanent all-optical switching of ferroelectric polarization. The general nature of the epsilon-near-zero regime means that the approach could be used to switch spontaneous order parameters in other systems.
