We report multipronged progress on the stochastic averaging approach to numerical
analytic continuation of imaginary-time correlation functions computed by quantum Monte …

Pursuing fractionalized particles that do not bear properties of conventional measurable
objects, exemplified by bare particles in the vacuum such as electrons and elementary …

This review paper describes the basic concept and technical details of sparse modeling and
its applications to quantum many-body problems. Sparse modeling refers to methodologies …

We report an implementation of the momentum space quantum Monte Carlo (QMC) method
on the interaction model for the twisted bilayer graphene (TBG). The long-range Coulomb …

Quantum dimer models are known to host topological quantum spin liquid phases, and it
has recently become possible to simulate such models with Rydberg atoms trapped in …

Frustrated magnets hold the promise of material realizations of exotic phases of quantum
matter, but direct comparisons of unbiased model calculations with experimental …

The interplay between lattice gauge theories and fermionic matter accounts for fundamental
physical phenomena ranging from the deconfinement of quarks in particle physics to …

Spectral probes, such as neutron scattering, are crucial for characterizing excitations in
quantum many-body systems and the properties of quantum materials. Among the most …

We show that for the magic-angle twisted bilayer graphene (TBG) away from the charge
neutrality point, although quantum Monte Carlo (QMC) simulations suffer from the sign …

The Landau-Ginzburg-Wilson theory of phase transitions precludes a continuous transition
between two phases that spontaneously break distinct symmetries. However, quantum …
