Together with Sergey Syzranov, I studied the conductivity of nodal line semimetals. These turn out to be qualitatively different from other semimetals, like Weyl or Dirac semimetals, because of an unusual screening that changes the nature of the Coulomb potential from 1/r to 1/r^2. Most...

A new paper in Nature Communications describes experiments that examine the "extreme quantum limit" of magnetic field in the material strontium titanate. We find evidence of a drastic reduction of the Fermi energy driven by the magnetic field, which leads to the formation of a spatially...

In a recent paper, Tianran Chen and I identified an interesting fractal structure of hopping conduction pathways in compensated semiconductors. The finding implies that hopping conductivity is unusually large and robust in these systems, and can appear two-dimensional even in a 3D system.

...In a series of recent papers, I explored ways to make bosonic particles with unusual properties using bilayer electronic systems. These works suggest new ways to realize quantum phases and quantum phase transitions of 2D bosons.

I am giving a seminar at the Applied Math Lab at NYU's Courant Institute in New York City.

I am giving a talk on Friday, Feb. 26, at Harvard Unversity as part of the Boston Area CarBon Nanoscience Meetings (BACON+).

The topic will be the possibility of creating continuously tunable bosonic phases (such as Bose-Einstein condensates, superfluids, and Wigner crystals) using...

I am giving a seminar on Tuesday, Feb. 23 at the Widely Applied Math seminar at Harvard University. My talk is entitled "Problems in Human Motion Planning", and it will deal with the statistical mechanics of pedestrian crowds and traffic networks.

I recently co-authored a book chapter that reviews what we know about the theory (and practice) of optimal offensive strategy in basketball. You can also read a popular summary of its contents here: http...

I recently delivered a talk for the Condensed Matter Theory seminar at MIT about Coulomb disorder and nonlinear screening effects in topological materials.

My colleague Stephen Guy and I wrote a paper about how to use player tracking data in basketball to build a network model of a basketball offense. The method allows one to infer player traits and predict the performance of untested lineups and strategies.
