Inclement Weather Event Updates

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”
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” 
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.
