We construct static axisymmetric multisolitons in the Einstein-Friedberg-Lee-Sirlin model. This theory features a complex scalar field which gains mass through its interaction with a real scalar field that has a non-zero vacuum expectation value. By performing three-dimensional numerical relativity simulations, we identify stable dipolar boson stars in specific regions of the parameter space. Based on the dipole results, non-rotating odd parity chains with and without gravity can also be constructed when the mass of the real scalar field is sufficiently small. However, chains beyond the dipole case are found to be unstable.

  1. Quantum fields in boson star spacetime

    gr-qc 2026-01 conditional novelty 6.0 of 10

    In boson star spacetimes, the renormalized quantum stress tensor has mostly positive energy density and negative radial pressure that grow with curvature, rivaling the classical stress in the most compact solutions.

  2. Bifurcations in Bosonic Stars: chains and rings from spherical solutions

    gr-qc 2025-01 conditional novelty 6.0 of 10

    Zero-modes of spherical bosonic stars under axisymmetric perturbations explain the bifurcations into chain, ring, and gyroscope-like bosonic star families.
