We numerically study the phase diagram of bosons tightly trapped in the lowest band of an optical lattice and dispersively coupled to a single-mode cavity field. The dynamics is encompassed by an extended Bose-Hubbard model. Here, the cavity-mediated interactions are described by a two-body potential term with a global range and by a correlated tunneling term where the hopping amplitude depends on a global observable. We determine the ground state properties in one dimension by means of the…

Continuous matrix-product states in inhomogeneous systems with long-range interactions

We develop the continuous matrix-product states approach for description of inhomogeneous one-dimensional quantum systems with long-range interactions. The method is applied to the exactly-solvable

Programmable interactions and emergent geometry in an array of atom clouds.

TLDR
By programming the distance dependence of the interactions, the realization of programmable non-local interactions in an array of atomic ensembles within an optical cavity is described, in which photons carry information between atomic spins12-19.

Self-organized topological insulator due to cavity-mediated correlated tunneling

Topological materials have potential applications for quantum technologies. Non-interacting topological materials, such as e.g., topological insulators and superconductors, are classified by means of

The ITensor Software Library for Tensor Network Calculations

TLDR
The philosophy behind ITensor, a system for programming tensor network calculations with an interface modeled on tensor diagrams, and examples of each part of the interface including Index objects, the ITensor product operator, tensor factorizations, and tensor storage types are discussed.

Haldane insulator in the 1D nearest-neighbor extended Bose-Hubbard model with cavity-mediated long-range interactions

Abstract In the one-dimensional Bose-Hubbard model with on-site and nearest-neighbor interactions, a gapped phase characterized by an exotic non-local order parameter emerges, the Haldane insulator.
