SUMMARY:Towards a Qubit-Lattice Model of the E_8 State
DESCRIPTION:Featuring David Long\nHosted by: Christopher Laumann\n\nPart of
	 the Biophysics/Condensed Matter Seminar Series.\n\nFor decades an importan
	t goal of condensed matter physics has been to classify and understand all 
	possible phases of matter\, and the phase transitions between them. Quantum
	 physics allows for interesting new phases\, called topological phases. It 
	is generally believed that\, in two dimensions\, we can classify all topolo
	gical phases of matter at an abstract level\, but we have no intuitive hand
	le on the vast majority of these. In particular\, the "E_8 state" is an int
	eresting two-dimensional topological phase of matter which is known to exis
	t\, but which is difficult to understand and work with. I conjecture a simp
	le model for the E_8 state based on a lattice of qubits coupled with a loca
	l Hamiltonian. While I have not proved this model is in the E_8 phase\, I h
	ave intermediate results which are important in their own right. These incl
	ude the construction of models achieving various simpler phases and a study
	 of the edges of some simple phases as they undergo a phase transition.
