Sachdev-Ye-Kitaev Models and Beyond: A Window into Non-Fermi Liquids

We present a review of the Sachdev-Ye-Kitaev (SYK) model of compressible
quantum many-body systems without quasiparticle excitations, and its
connections to various theoretical studies of non-Fermi li ...

Variational solutions to fermion-to-qubit mappings in two spatial dimensions

Through the introduction of auxiliary fermions, or an enlarged spin space,
one can map local fermion Hamiltonians onto local spin Hamiltonians, at the
expense of introducing a set of additional constr ...

Symmetric Jordan-Wigner transformation in higher dimensions

The Jordan-Wigner transformation is traditionally applied to one dimensional
systems, but recent works have generalized the transformation to fermionic
lattice systems in higher dimensions while keepi ...

Tuning long-range fermion-mediated interactions in cold-atom quantum simulators

Engineering long-range interactions in cold-atom quantum simulators can lead
to exotic quantum many-body behavior. Fermionic atoms in ultracold atomic
mixtures can act as mediators, giving rise to lon ...

Tricritical point in the quantum Hamiltonian mean-field model

Engineering long-range interactions in experimental platforms has been
achieved with great success in a large variety of quantum systems in recent
years. Inspired by this progress, we propose a genera ...

Discovering Quantum Phase Transitions with Fermionic Neural Networks

Deep neural networks have been extremely successful as highly accurate wave
function ans\"atze for variational Monte Carlo calculations of molecular ground
states. We present an extension of one such ...

Universal thermodynamics of an SU($N$) Fermi-Hubbard Model

The SU(2) symmetric Fermi-Hubbard model (FHM) plays an essential role in
strongly correlated fermionic many-body systems. In the one particle per site
and strongly interacting limit ${U/t \gg 1}$, it ...

Intertwined states at finite temperatures in the Hubbard model

Significant advances in numerical techniques have enabled recent
breakthroughs in the study of various properties of the Hubbard model - a
seemingly simple, yet complex model of correlated electrons t ...

High-order expansion around BCS theory

We demonstrate that high-order diagrammatic expansion around BCS theory is a
viable generic unbiased approach for strongly correlated fermions in
superconducting or superfluid phases. For the 3D attra ...

Numerically exact quantum gas microscopy for interacting lattice fermions

A numerical method is presented for reproducing fermionic quantum gas
microscope experiments in equilibrium. By employing nested componentwise direct
sampling of fermion pseudo-density matrices, as th ...
