A conventional laser consists of three main components: a gain medium, a cavity, and an energy source. Researchers at Princeton and the University of Maryland Joint Quantum Institute have demonstrated a nanoscale laser that is driven by a single electron tunneling events.

The chiral anomaly in a Dirac semimetal

The notion of handedness or chirality (Greek for “hand”) is ubiquitous in chemistry, biology and physics. In quantum field theory, all massless particles (e.g. neutrinos) are chiral. The left- and right-handed populations are independent and never mix (Fig. A). However, inter-conversion occurs once electromagnetic fields are turned on. The field-induced mixing -- known as the chiral anomaly – produces an “axial current”. The effect was predicted in 1983 to occur in crystals. This was recently confirmed in the Dirac semimetal Na3Bi [1].

Teachers as Scholars - Materials Science Program
On November 10 and 17, 2015, 18 teachers visited the Princeton Center for Complex Materials as part of Teacher Prep's program to learn about materials science and how to apply it to the classroom. This unique PCCM program is part of a larger "Teachers as Scholars" initiative as part of Princeton University's Teacher Preparation program.

UMN Materials Research Science and Engineering Center (2014)
American Indian Visit Day
In 2015, the University of Minnesota MRSEC expanded its American Indian Outreach activities with the inaugural American Indian Visit Day. On November 7, 2015, 270 American Indian middle and high school students were invited to UMN for a day of activities to introduce opportunities in STEM available at UMN. The students participated in hands on activities presented by each of the three MRSEC IRGs exposing them to research in multiple science and engineering fields. Additionally, the students toured campus cultural offices and heard from American Indian student and alumni speakers.

Liquid Crystal Nano-Flowers
The nanoscale structures of liquid crystals are rarely more exotic
than that of the sponge phases of bent-core molecules, visualized here in an
electron microscope image made by researchers at the Liquid Crystal Materials
Research (MRSEC) Center of the University of Colorado, Boulder. The image shows a plant stalk-like network
that gives the appearance of a grayscale photo of dense tropical foliage, but here the stalk
