DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Kadanoff/7/"
 >Dual perspective on quantum Hall to insulator transitions</a>\nby Sri Rag
 hu (Stanford) as part of Kadanoff seminars\n\n\nAbstract\nQuantum Hall to 
 insulator transitions (QHITs) are among the oldest and most studied exampl
 es of quantum critical phenomena.  In this talk I will discuss problems th
 at still remain open in this subject\, and present a dual approach to QHIT
 s based on composite fermion representations.  I discuss the mean-field an
 d fluctuational aspects of the dual theories\, and discuss how they provid
 e a complementary understanding  - and in many instances\, a conceptual ad
 vantage - to current descriptions of QHITs based on the electron represent
 ation.\n
