Discovery Sheds New Light on Photonic Quantum Technologies
In a paper published in Nature Physics, a research team led by Dominik Schneble, a professor in the Department of Physics and Astronomy at Stony Brook University, reports the realization of novel quasiparticles made entirely out of ultracold atomic matter,

The new research allows for studies of such systems with the high flexibility and control of an analog quantum simulation, promising new experimental insights into the physics underlying some of the most important QIST platforms.

New Insights on Cold Ion-Neutral Processes
Dr. Jesus Perez Rios, a new faculty member at the Department of Physics and Astronomy from Stony Brook University, and collaborators find evidence of a reaction between a single ion and molecules at temperatures below 100 µk.

The observed chemical reaction showed that ion-molecule collisions lead inexorably to forming a molecular ion as a product state

Novel Interpretation of Drude Weight
Dr. Cyrus Dreyer and collaborators have found new results for Born effective charges (BECs) in conductors. BECs, defined as the electrical polarization induced by displacement of atoms, are key quantities for understanding how deformations and electric fields are coupled in insulating materials.
“ This work extends the concept of dynamical charges to metals and doped semiconductors as well as providing a novel physical interpretation of the Drude weight in terms of lattice dynamics, instead of transport. ”
