报告摘要:Analogy gravity plays an important role to investigate general relativity phenomena. Especially some analog models from various systems in the laboratoryenvironment have been motivatedby the possibility of investigatinggeneral relativityphenomena not readilyaccessible in their cosmologicalcounterparts. One of profound examples isHawking–Unruh radiation emulatedfrom a Fermi-degenerate liquid, a superconductor, opticalfiber, nonlinear crystal, ion ring, and Bose–Einsteincondensates.In addition, given form invariance of Maxwell’s equations between the complex inhomogeneous media and the background of an arbitrary spacetime metric, the proposaland development of transformation optics provide an alternative way to study the curved spacetime. In this talk, I will give our group’s recent experimental work about emulating general relativity phenomena, such as artificial black hole1, Einsteinring2, cosmic string3, and the fermion-pair production in close proximity to the black hole. Furthermore, the combination between transformation optics and quantum optics may have potential applications to study relativistic quantum information.
