DESCRIPTION:[b]Speaker: Ralph Kaufmann [/b](Purdue University).\n\n[b]Abst
 ract: [/b]\nQuantum phase transitions are a key part of the quantum lands
 cape. These appear in mathematical systems and real materials. They are p
 otentially useful for quantum computing and quantum sensing. In joint wor
 k with Mohamad Mousa and Birgit Kaufmann-Wehefritz\, we showed that any a
 bstract phase diagram of Chern insulators can be achieved in a continuum 
 model. Furthermore\, we gave sequences of higher Chern models built on ti
 ght-binding models exhibiting an infinite sequence of Chern numbers. In n
 ewer developments these constructions also will shed light on MPS and mat
 erials with symmetries. We also conjecture that they will be useful for q
 uantum error correction.
