DESCRIPTION:Speaker: Artem Volosniev\nhosted by Mikhail Lemeshko\nAbstract:
   The energy spectrum of lead-halide perovskites (LHPs) in the vicinity o
 f the band gap resembles that of a Dirac equation. This observation establ
 ishes a fruitful analogy between condensed matter and high-energy physics.
  Indeed\, on the one hand\, it allows one to use well-established theoreti
 cal techniques to study strong-field effects in LHPs. On the other hand\, 
 it paves the way for the first experimental observations of textbook pheno
 mena in high-energy physics.The talk will first introduce LHPs as a Dirac 
 semiconductor. This will lay down the base for the discussion of a recent 
 observation of the dynamical Schwinger effect in LHPs. Besides being of ge
 neral interest\, this observation implies a number of useful applications\
 , in particular detection of strong electric fields\, also demonstrated in
  the laboratory. Further\, I will argue that LHPs can potentially be emplo
 yed to study Dirac-Pauli physics – an extension of the Dirac equation du
 e to Pauli\, which has found limited use in high-energy physics. The prese
 ntation is based on arXiv: 2406.05032 and arXiv:2407.04450.
