Abstract: In metals near quantum phase transitions, critical modes can significantly slow down the motion of electrons through a red shift that dilates frequency. If such quantum corrections are anisotropic, the momentum-dependent red shift can create a curved momentum-spacetime geometry. In this talk, we will discuss an example where a strongly curved momentum-spacetime geometry emerges dynamically - in a certain limit, the emergent geometry becomes analogous to that of the black hole horizon. Its experimental implication for the cyclotron motion of electron will be discussed.
