Synthetic dimensions using ultrafast free electrons
Yiming Pan, Bin Zhang, Daniel Podolsky
We propose a synthetic dimension for ultrafast free electrons based on the discrete energy sidebands in photon-induced near-field electron microscopy (PINEM). The PINEM synthetic d…

Phonon-induced modification of quantum criticality
Abhisek Samanta, Efrat Shimshoni, Daniel Podolsky
We study the effect of acoustic phonons on the quantum phase transition in the O() model. We develop a renormalization group analysis near (3+1) space-time dimensions and derive…
