The successes and limitations of statistical sampling for a sequence of models studied in the
context of lattice QCD are discussed and the need for new methods to deal with finite …

Studying QCD and other gauge theories on quantum hardware requires the preparation of
physically interesting states. The variational quantum eigensolver provides a way of …

We derive a representation for a lattice U (1) gauge theory with exponential convergence in
the number of states used to represent each lattice site that is applicable at all values of the …

The time evolution of an Ising model with large driving fields over discrete time intervals is
shown to be reproduced by an effective XXZ-Heisenberg model at leading order in the …

We use the higher-order tensor renormalization group method to study the two-dimensional
generalized XY model that admits integer and half-integer vortices. This model is the …

In recent years simulations of chemistry and condensed materials has emerged as one of
the preeminent applications of quantum computing, offering an exponential speedup for the …

For performing regression tasks involved in various physics problems, enhancing the
precision or equivalently reducing the uncertainty of regression results is undoubtedly one of …

We reanalyze some critical exponents of the O (N) model within the functional
renormalization group (FRG) approach in the local potential approximation (LPA). We use …

We propose a method to construct a tensor network representation of partition functions
without singular value decompositions nor series expansions. The approach is …
