Off-diagonal series expansion for quantum partition functions

We derive an integral-free thermodynamic perturbation series expansion for quantum partition functions which enables an analytical term-by-term calculation of the series. The expansion is carried out

Permutation matrix representation quantum Monte Carlo

We present a quantum Monte Carlo algorithm for the simulation of general quantum and classical many-body models within a single unifying framework. The algorithm builds on a power series expansion of

The Ising model with a transverse field. II. Ground state properties

For Pt. I see ibid., vol. 4, 2359 (1971). The properties of the Ising model with a transverse field, with the Hamiltonian written H=- Gamma Sigma iSix-1/2 Sigma i,jJijSizSjz, are studied by

Rational Krylov approximation of matrix functions: Numerical methods and optimal pole selection

TLDR
This work reviews various rational Krylov methods for the computation of large‐scale matrix functions and focuses on the rational Arnoldi method and variants thereof, namely, the extended Krylov subspace method and the shift‐and‐invert Arnoldi methods.

Evaluating Matrix Functions by Resummations on Graphs: The Method of Path-Sums

We introduce the method of path-sums, which is a tool for analytically evaluating a primary function of a finite square discrete matrix based on the closed-form resummation of infinite families of

Ising model in a transverse field. I. Basic theory

A brief review is first made of systems for which the spin-iIsing model in a transverse field provides a useful description (insulating magnetic systems, order-disorder ferroelectrics, cooperative

A SET of numerical data, whether obtained from theory or experiment, gives rise to mathematical problems of interest and importance. The consideration of these problems now forms an important branch

Network Properties Revealed through Matrix Functions

TLDR
A general class of measures based on matrix functions is introduced, and it is shown that a particular case involving a matrix resolvent arises naturally from graph-theoretic arguments.

Eigenspaces for Graphs

TLDR
The feasibility of using graph-based descriptions to learn the view structure of 3D objects is investigated and how multidimensional scaling may be used to generate eigenspaces from a set of pairwise distances between graphs is investigated.
