Fermi liquid theory predicts that electron-electron scattering will contribute $\rho_{e-e}(\omega,T)=A \left[(\hbar\omega)^2+b(\pi k_B T)^2 \right]$ to the frequency-dependent resistivity of any metal at low temperatures and frequencies. In its simplest form, the theory further predicts that the temperature and frequency dependence are related by $b=4$, but numerous experimental studies have...

The influence of disorder on correlated electron systems remains poorly understood. Recent work [1], [2] by Johri and Bhatt shows singular behavior in the density of states (DOS) of non-interacting disordered systems. This is surprising because there was a significant and unsuccessful effort to find a singularity in the DOS after Anderson’s prediction of localization in 1958. Furthermore, in...

We present a scalable algorithm for computing Rényi entanglement entropies in systems of itinerant bosons in the spatial continuum via quantum Monte Carlo. This method is applicable to the study of spatial mode entanglement, particle partitioned entanglement, and the entanglement of particles under a spatial partitioning. We demonstrate its utility by studying a non-trivial interacting Bose...
