Many-Configuration Markov-Chain Monte Carlo
Fedor Šimkovic, Riccardo Rossi
We propose a minimal generalization of the celebrated Markov-Chain Monte Carlo algorithm which allows for an arbitrary number of configurations to be visited at every Monte Carlo s…
Mott insulating states with competing orders in the triangular lattice Hubbard model
Alexander Wietek, Riccardo Rossi, Fedor Šimkovic +6
The physics of the triangular lattice Hubbard model exhibits a rich phenomenology, ranging from a metal-insulator transition, intriguing thermodynamic behavior, and a putative spin…
Efficient One-Loop-Renormalized Vertex Expansions with Connected Determinant Diagrammatic Monte Carlo
Fedor Šimkovic, Riccardo Rossi, Michel Ferrero
We present a technique that enables the evaluation of perturbative expansions based on one-loop-renormalized vertices up to large expansion orders. Specifically, we show how to com…
Renormalized perturbation theory at large expansion orders
Riccardo Rossi, Fedor Simkovic, Michel Ferrero
We present a general formalism that allows for the computation of large-order renormalized expansions in the spacetime representation, effectively doubling the numerically attainab…
High-precision numerical solution of the Fermi polaron problem and large-order behavior of its diagrammatic series
K. Van Houcke, F. Werner, R. Rossi
We introduce a simple determinant diagrammatic Monte Carlo algorithm to compute the ground-state properties of a particle interacting with a Fermi sea through a zero-range interact…
Direct sampling of the self-energy with Connected Determinant Monte Carlo
Riccardo Rossi
In this note, we present an efficient algorithm to sample directly the self-energy in the framework of the Connected Determinant technique. The introduction of the formalism of man…
