Quantum Monte Carlo Methods

James E. Gubernatis, Naoki Kawashima, Philipp Werner

Featuring detailed explanations of the major algorithms used in quantum Monte Carlo simulations, this is the first textbook of its kind to provide a pedagogical overview of the field and its applications. The book provides a comprehensive introduction to the Monte Carlo method, its use, and its foundations, and examines algorithms for the simulation of quantum many-body lattice problems at finite and zero temperature. These algorithms include continuous-time loop and cluster algorithms for quantum spins, determinant methods for simulating fermions, power methods for computing ground and excited states, and the variational Monte Carlo method. Also discussed are continuous-time algorithms for quantum impurity models and their use within dynamical mean-field theory, along with algorithms for analytically continuing imaginary-time quantum Monte Carlo data. The parallelization of Monte Carlo simulations is also addressed. This is an essential resource for graduate students, teachers, and researchers interested in quantum Monte Carlo techniques.

Real-frequency diagrammatic Monte Carlo at finite temperature

J. Vučičević, Michel Ferrero

Diagrammatic expansions are a central tool for treating correlated electron systems. At thermal equilibrium, they are most naturally defined within the Matsubara formalism. However, extracting any dynamic response function from a Matsubara calculation ultimately requires the ill-defined analytical continuation from the imaginary- to the real-frequency domain. It was recently proposed [A. Taheridehkordi et al., Phys. Rev. B 99, 035120 (2019)] that the internal Matsubara summations of any interaction-expansion diagram can be performed analytically by using symbolic algebra algorithms. The result of the summations is then an analytical function of the complex frequency rather than Matsubara frequency. Here we apply this principle and develop a diagrammatic Monte Carlo technique which yields results directly on the real-frequency axis. We present results for the self-energy $\mathrm{\ensuremath{\Sigma}}(\ensuremath{\omega})$ of the doped $32\ifmmode\times\else\texttimes\fi{}32$ cyclic square-lattice Hubbard model in a nontrivial parameter regime, where signatures of the pseudogap appear close to the antinode. We discuss the behavior of the perturbation series on the real-frequency axis and in particular show that one must be very careful when using the maximum entropy method on truncated perturbation series. Our approach holds great promise for future application in cases when analytical continuation is difficult and moderate-order perturbation theory may be sufficient to converge the result.

Functional-Integral Approaches and Diagrammatic Many-Body Theory of the Hubbard Model

Cláudio Andrade Macedo, M. D. Coutinho Filho

We are able to demonstrate that we can attain a proper comprehension of the functional-integral method as applied to the Hubbard and similar model systems. This is done in the context of diagrammatic perturbation theory. In particular, new as well as well-known exact relations among physical quantities of interest are derived in the context of the formalism.

Hubbard model: Functional-integral approach and diagrammatic perturbation theory

Cláudio Andrade Macedo, Mauriaacio D. Coutinho-Filho

We present a careful analysis of the functional-integral approach as applied to the Hubbard model in the framework of diagrammatic perturbation theory. It is demonstrated that a proper comprehension of the formalism can be attained and that the functional-integral method is a very systematic technique, free of ambiguity. In particular, additional exact relations among physical quantities of interest are derived in the context of the formalism.

Algorithm for computing perturbation series of dynamical mean field theory

Corentin Bertrand, Michel Ferrero, Olivier Parcollet

We show how to use diagrammatic techniques to compute the weak-coupling perturbation series of the self-consistent solution to a dynamical mean field theory (DMFT) problem. This approach constitutes an alternative to using diagrammatic techniques directly as an impurity solver. It allows one to bypass the need of multiple perturbative series resummations within the DMFT self-consistency loop. It can be applied at or out of equilibrium, with any diagrammatic formalism, such as real times, imaginary times, or Matsubara frequencies formalisms. As a proof of principle, we illustrate our method with the half-filled Hubbard model on the Bethe lattice in the DMFT approximation, using quantum quasi Monte Carlo (QQMC) to obtain the impurity perturbation series on the real time axis.

Optimal grouping of arbitrary diagrammatic expansions via analytic pole structure

Amir Taheridehkordi, Stephanie H. Curnoe, J. P. F. LeBlanc

We present a general method to optimize the evaluation of Feynman diagrammatic expansions which uses an automated symbolic assignment of momentum/energy conserving variables to each diagram. With this symbolic representation, we utilize the pole structure of each diagram to sort the Feynman diagrams into groups that are likely to contain nearly equal or nearly canceling diagrams, and we show that for some model parameters this cancellation is exact. This allows for a potentially massive cancellation during the numerical integration of internal momenta variables, leading to an optimal suppression of the ``sign problem'' and hence reducing the computational cost. Although we define these groups using a frequency space representation, the equality or cancellation of diagrams within the group remains valid in other representations such as imaginary time used in standard diagrammatic Monte Carlo. As an application of the approach, we apply this method, combined with algorithmic Matsubara integration (AMI) [A. Taheridehkordi, S. H. Curnoe, and J. P. F. LeBlanc, Phys. Rev. B 99, 035120 (2019)] and Monte Carlo methods, to the Hubbard model self-energy expansion on a 2D square lattice, which we evaluate and compare with existing benchmarks.
