Mathematical Physics Seminar - Ron Peled, Tel Aviv University - Surface depinning under the two-dimensional hammock potential We consider a random two-dimensional surface satisfying a Lipschitz constraint. The surface is uniformly chosen from the set of all real-valued Lipschitz functions on a two-dimensional discrete torus. Our main result is that the surface delocalizes, having fluctuations whose variance is at least logarithmic in the size of the torus. Our technique follows closely the approach of Richthammer, who developed a variant of the Mermin-Wagner method applicable to hard-core constraints. The result answers an open question mentioned by Brascamp, Lieb and Lebowitz on the hammock potential. Extensions and related open problems will also be discussed. Joint work with Piotr Miłoś. Jadwin A06 · 4:30 p.m.– 6:00 p.m. |

Hamilton Colloquium Series - Amir Yacoby, Harvard University - “Quantum Information Processing and Metrology Using Few Electron Spins in Solids” Quantum computing and information processing use quantum two level systems as their building blocks. Solid-state implementations of quantum bits use, for example, single or few electron spins confined to small spatial dimensions. Harnessing the interaction of such electron spins with their environment offers intriguing possibilities for coherent electrical manipulation and controlled generation of entanglement with promising applications in nanoscale imaging and metrology. Jadwin A10 · 4:30 p.m.– 5:30 p.m. |

High Energy Theory Seminar - Ofer Aharony, Weizmann Institute - "From 4d dualities to 3d dualities" It was found in the 1990s that many pairs of supersymmetric gauge theories with four supercharges, both in four and in three space-time dimensions, have the same low-energy dynamics. I will describe how to find relations between the low-energy dualities in four and in three dimensions. This talk is based on ongoing work, in collaboration with Shlomo Razamat, Nati Seiberg and Brian Willett. PCTS Seminar Room · 1:30 p.m.– 3:00 p.m. |
