DESCRIPTION:Speaker: Suraj Hegde\nhosted by Mikhail Lemeshko\nAbstract: Haw
 king radiation and Unruh effect are one of the most fascinating and puzzli
 ng consequences of the interplay between quantum mechanics and relativity.
  In the simplest setting of Unurh effect\, an accelerating observer percei
 ves the Minkowski vacuum as a thermal bath. In the context of black holes\
 , this is manifest as the Hawking radiation. This puzzling thermality\, ar
 ises from a relation between symmetry operation that preserves the causal 
 structure of the spacetime(The Lorentz boost) and the Hamiltonian that gen
 erates time translations in the accelerating(Rindler) space. In this talk\
 , I show that this 'Rindler Hamiltonian' has a structural parallel in the 
 quantum Hall system with an applied saddle potential\, which is an interes
 ting system from the condensed matter perspective itself. All of this phys
 ics ultimately boils down to studying the quantum mechanical scattering of
 f an inverted harmonic oscillator potential. This also uncovers novel time
 -decaying resonant modes(Quasinormal modes) in the quantum Hall set up. Re
 cent LIGO measurements actually observed the quasinormal modes from a blac
 k hole merger. Thus\, we show parallels of black hole phenomena in a quant
 um Hall system and also uncover novel features in the quantum Hall system.
