SUMMARY:Photonic topological insulators and pseudomagnetism\, Faculty 
 Candidate Seminar\, Mikael Rechtsman\, Technion - Israel Institute of 
 Technology
DESCRIPTION:I will present two examples in which aEuro~fictitious fiel
 dsaEuroTM lead to surprising photonic effects that would be difficult 
 (if not impossible) to achieve with real fields.  Firstly\, I will pre
 sent the first observation of the topological protection of light - a 
 aEuro~Photonic Floquet Topological InsulatoraEuroTM [1].  The structur
 e is an array of coupled helical waveguides (the helicity generates a 
 fictitious circularly-polarized electric field that leads to the TI be
 havior).  Second\, I will demonstrate artificial magnetic fields (aEur
 o~pseudomagnetismaEuroTM) in photonic lattices [2]. The pseudomagnetic
  field is generated by inhomogeneously straining the system (thus brea
 king periodicity)\, and leads to photonic Landau levels with very high
  photonic density of states.  Potential applications include robust ph
 otonic devices and strong light-matter interaction over large areas.<b
