Many‐body open quantum systems (OQSs) have a profound impact on various
subdisciplines of physics, chemistry, and biology. Thus, the development of a computer …

A major challenge in the field of correlated electrons is the computation of dynamical
correlation functions. For comparisons with experiment, one is interested in their real …

The localization-delocalization transition is at the heart of strong correlation physics.
Recently, there is great interest in multiorbital systems where this transition can be restricted …

Multipoint vertex functions, and the four-point vertex in particular, are crucial ingredients in
many-body theory. Recent years have seen significant algorithmic progress toward …

Real-time calculations in tensor networks are strongly limited in time by entanglement
growth, restricting the achievable frequency resolution of Green's functions, spectral …

The interplay between delocalisation and repulsive interactions can cause electronic
systems to undergo a Mott transition between a metal and an insulator. Here we use neural …

We present an approach to tame the growth of entanglement during time evolution by tensor
network methods. It combines time evolution in the complex plane with a perturbative and …

We report spin-polarized scanning tunneling microscopy measurements of an Anderson
impurity system in MoS 2 mirror-twin boundaries, where both the quantum-confined impurity …

We show that the remarkably small Fermi-liquid coherence scale and large effective mass
observed in LiV $ _2 $ O $ _4 $ are due to the proximity of a Hund-assisted orbital-selective …

We present a minimally entangled typical thermal state quantum impurity solver for general
multiorbital systems at finite temperatures. We introduce an improved estimator for the single …
