Universal dimerized quantum droplets in a one-dimensional lattice

I Morera, GE Astrakharchik, A Polls, B Juliá-Díaz - Physical review letters, 2021‏ - APS
The ground-state properties of two-component bosonic mixtures in a one-dimensional
optical lattice are studied both from few-and many-body perspectives. We rely directly on a …

Beyond hard-core bosons in transmon arrays

O Mansikkamäki, S Laine, A Piltonen, M Silveri - PRX Quantum, 2022‏ - APS
Arrays of transmons have proven to be a viable medium for quantum information science
and quantum simulations. Despite their widespread popularity as qubit arrays, there remains …

Observation of pair tunneling and coherent destruction of tunneling in arrays of optical waveguides

S Mukherjee, M Valiente, N Goldman, A Spracklen… - Physical Review A, 2016‏ - APS
We report on the experimental realization of a photonic system that simulates the one-
dimensional two-particle Hubbard model. This analogy is realized by means of two …

Arbitrary synthetic dimensions via multiboson dynamics on a one-dimensional lattice

The synthetic dimension, a research topic of both fundamental significance and practical
applications, has been attracting increasing attention in recent years. In this paper, we …

Lattice two-body problem with arbitrary finite-range interactions

M Valiente - Physical Review A—Atomic, Molecular, and Optical …, 2010‏ - APS
We study the exact solution of the two-body problem on a tight-binding one-dimensional
lattice, with pairwise interaction potentials which have an arbitrary but finite range. We show …

Pairs, trimers, and BCS-BEC crossover near a flat band: Sawtooth lattice

G Orso, M Singh - Physical Review B, 2022‏ - APS
We investigate pairing and superconductivity in the attractive Fermi-Hubbard model on the
one-dimensional sawtooth lattice, which exhibits a flat band by fine-tuning the hop** rates …

The few-atom problem

DS Petrov - Many-Body Physics With Ultracold Gases (Les …, 2012‏ - books.google.com
The few-body problem plays a very important role in the physics of ultracold gases. It
describes the structure of molecules and their formation in three-body collisions (three-body …

Quasi-soliton scattering in quantum spin chains

Rise and fall of a bright soliton in an optical lattice

P Naldesi, JP Gomez, B Malomed, M Olshanii… - Physical Review Letters, 2019‏ - APS
We study an ultracold atomic gas with attractive interactions in a one-dimensional optical
lattice. We find that its excitation spectrum displays a quantum soliton band, corresponding …
