Note on Hawking-Unruh effects in graphene

Abstract

"Beltrami-shaped graphene sheets have been recently proposed as analogs of curved spacetimes with Hawking-Unruh e?ects detected through typi-cal condensed matter measurements involving scanning tunneling micro-scopes and spectroscopy. However, such deformed sheets, if ever fabri-cated, will contain large strain-induced pseudomagnetic ?elds with im-portant guiding e?ects on the motion of the electrons in the conduction band. Besides, possible surface polariton and plasmon modes are known to be important players in the radiative heat transfer which takes place in the natural near-?eld nanoscale experimental conditions. Therefore, we suggest that the latter class of experiments could shed light on phenomena related to the black hole membrane paradigm instead"
