Due to the inclement weather the following events have been rescheduled:
Della Pietra Lecture Series – General Public Lecture
Date: Tuesday, February 9, 2016
Wine and Cheese Reception: 5:00 pm, Simons Center Lobby and Art Gallery
Lecture: 6:00pm, Simons Center Auditorium, Room 103
Title: “Science from a sheet of paper”
Abstract:
Starting from just a sheet of paper, by folding, stacking, crumpling, tearing, we will explore a rich variety of sciences, from geometry and magic tricks to elasticity and the traditional Japanese art of origami. Much of the lecture consists of actual table-top demos, which you can try later with friends and family.
So, take a sheet of paper. . .

Title: “Discovery of the chiral magnetic effect in condensed matter”
Abstract:
The chiral magnetic effect is the generation of electric current induced by chirality imbalance in the presence of magnetic field. It is a macroscopic manifestation of the quantum anomaly in relativistic field theory of chiral fermions – a dramatic phenomenon arising from a collective motion of particles and antiparticles in the Dirac sea. The recent availability of Dirac semimetals with chiral quasi-particles opens a fascinating possibility to study this phenomenon in condensed matter experiments. In this talk, I will report on the first observation of chiral magnetic effect through the measurement of magneto-transport in zirconium pentatelluride, ZrTe5 [BNL-Stony Brook-Princeton-Berkeley Coll., Nature Physics, to appear]. Our angle-resolved photoemission spectroscopy experiments show that this material’s electronic structure is consistent with a 3D Dirac semimetal. We observe a large negative magnetoresistance when magnetic field is parallel with the current. The measured quadratic field dependence of the magnetoconductance is a clear indication of the chiral magnetic effect. I will also discuss recent observations of the effect in other materials, and directions for future research.
