A central challenge in modern condensed matter physics is developing the tools for
understanding nontrivial yet unordered states of matter. One important idea to emerge in this …

For quantum many-body systems with short-range correlations (SRCs), the intimate
relationship between their magnitude, the behavior of the single-particle occupation …

We discuss the pseudogap regime in the unitary Fermi gas (UFG), with a particular
emphasis on the auxiliary-field quantum Monte Carlo (AFMC) approach. We discuss …

We numerically emulate noisy intermediate-scale quantum (NISQ) devices and determine
the minimal hardware requirements for two-site hybrid quantum–classical dynamical mean …

In a classical plasma the momentum distribution, n (k), decays exponentially, for large k, and
the same is observed for an ideal Fermi gas. However, when quantum and correlation …

We provide a fresh perspective on the pseudogap physics for attractive fermions as
described by the three-dimensional Hubbard model. The pseudogap in the single-particle …

This article provides a brief review of how various spectroscopies have been used to
investitage many-body quantum phenomena in the context of ultracold Fermi gases. In …

Over the past two decades, many studies in the density functional theory context revealed
new aspects and properties of strongly correlated superfluid quantum systems in numerous …

We present a general method for the high-temperature expansion of the self-energy of
interacting particles. Although the method is valid for fermions and bosons, we illustrate it for …

Nonlocal effective interactions are inherent to non-relativistic quantum many-body systems,
but their systematic resummation poses a significant challenge known as the``vertex …
