Hybrid Fracton Orders
Nathanan Tantivasadakarn (Harvard) Video Title: Hybrid Fracton Orders Abstract: I will introduce a family of gapped quantum phases that exhibit the phenomenology of both conventional three-dimensional topological orders and fracton orders called “Hybrid Fracton Orders”. First, I will present the simplest example of such an order: the “Hybrid X-cube” model, where excitations can be labeled identically to […]
Moduli spaces of stable pairs on algebraic surfaces
Interdisciplinary Science Seminar Speaker: Yinbang Lin (Tongji University) Title: Moduli spaces of stable pairs on algebraic surfaces Abstract: As a variant of Grothendieck’s Quot schemes, we introduce the moduli space of limit stable pairs. We show an example over a smooth projective algebraic surface where there is a virtual fundamental class. We are able to […]
The nu=5/2 enigma: Recent insights from theory and experiment
peaker: Ady Stern & David Mross (Weizmann) Speaker: Ady Stern & David Mross (Weizmann Title: The nu=5/2 enigma: Recent insights from theory and experiment Abstract: Non-Abelian phases of matter have long inspired quantum physicists across various disciplines. The strongest experimental evidence of such a phase arises in quantum Hall systems at the filling factor 5/2 […]
