DESCRIPTION:Holography of the lowest Landau level problem\nAjay Mohan (TIFR
  Mumbai)\n&nbsp\;\n\nWe consider a system of fermions on a 2 dimensional p
 lane with a perpendicular magnetic field (also called the Landau problem) 
 whose spectrum is labelled by Landau levels. While it is well-known that t
 here is a classical description of the lowest Landau level in terms of an 
 effectively 1 dimensional constrained system\, our recent findings suggest
  that this 1D-2D correspondence holds quantum-mechanically as well. Moreov
 er\, we find to our surprise that while certain physical quantities of the
  original 2D theory have a description in terms of an equivalent 1D theory
  (like the 2D fermion density of an N-fermion state)\, certain other quant
 ities (like the ground state entanglement entropy) partially remember the 
 2D origin of the system. In this talk\, I will present these findings in d
 etail.
