Through the Atomic Scale Looking Glass
In Through the Looking Glass, Alice steps through a mirror into a world in which everything is its mirror image. Realizing that writing in books is reversed, Alice wonders what has happened on the atomic scale.

The materials genome gets hot!

V. Stevanovic, R. O’Hayre, A. Zakutayev REMRSEC, NSF DMR-0820518
The goal of this seed project is to bring first-principles theory closer to experimental reality.
The motion of charge carriers in ruthenates is imaged using a technique known as Angle Resolved Photoemission Spectroscopy (ARPES).

Simple stretch “flips” the sign of charge carriers
Electricity is the flow of charged particles through a material, such as a wire — a process that resembles a river of water molecules flowing through a canyon. But are the charged particles positive or negative?

Down the rabbit hole: Sinking electrons in a Weyl sea

H. Inoue, Princeton University A. Gyenis, Princeton University Z. Wang, Princeton University J. Li, Princeton University S. Oh, Princeton University S. Jiang, Princeton University N. Ni, Princeton University B. A. Bernevig, Princeton University A. Yazdani, Princeton University Inoue, et al., Science 351, 1184 (2016)
Weyl semimetals are newly discovered topological electronic materials in which surface electrons (Fermi arcs) are topologically connected with those of the bulk. Princeton researchers have found experimental evidence that electrons can transverse the bulk through the special momentum states, called Weyl points, moving between opposing surfaces.

Single photon bound states in microwave photonic crystals

Andrew Houck, Princeton University Reference: Yanbing Liu and Andrew Houck, “Quantum Electrodynamics Near a Photonic Bandgap,” arXiv:1603.02998, submitted (2016).
Photonic crystals provide an extremely powerful toolset for manipulation of optical dispersion and density of states. Princeton researchers' recent work opens exciting prospects for engineering long-range spin models in the circuit QED architecture, and new opportunities for dissipative quantum state engineering.

MAPLE of Polymer Films for Morphology Control

Craid Arnold, Princeton Univesity Lynn Loo, Princeton University Rodney Priestley, Princeton University
Princeton researchers found that deposition temperature can significantly affect the stability of liquid phase PEO in MAPLE (matrix assisted pulsed laser evaporation)-deposited films, which results in different crystallization kinetics.
