The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

We study the ground-state phase diagram of a spin-1 2 frustrated XXZ ladder, in which two
antiferromagnetic chains are coupled by competing rung and diagonal interactions, J⊥ and …

We study the ground-state phase diagram of a spin-1 2 XXZ model with a chirality-chirality
interaction (CCI) on a two-leg ladder. This model offers a minimal setup to study an interplay …

We study the entanglement spectrum (ES) and entropy between two coupled Tomonaga-
Luttinger liquids (TLLs) on parallel periodic chains. This problem gives access to the …

We consider a two-leg Bose-Hubbard ladder in the presence of a magnetic flux. We make
use of Gross-Pitaevskii, Bogoliubov, bosonization, and renormalization group approaches to …

We consider a system of two coupled Tomonaga-Luttinger liquids (TLL's) on parallel chains
and study the Rényi entanglement entropy S n between the two chains. Here the …

We study a two-species bosonic Hubbard model on a two-dimensional square lattice by
means of quantum Monte Carlo simulations. In addition to the usual contact repulsive …

We study the decay rate Γ (k) of density excitations of two-component Bose-Einstein
condensates at zero temperature. Those excitations, where the two components oscillate in …

We study the recently introduced self-pinning transition [Phys. Rev. Lett. 128, 053401
(2022)] in a quasi-one-dimensional two-component quantum gas in the case where the …

The interplay of quantum statistics, interactions, and temperature is studied within the
framework of the bosonic two-component theory with repulsive delta-function interaction in …
