Gravitating scalar stars in the large D limit
Published 2018-11-01“…The leading order equations in the 1/D expansion can be solved analytically, providing a large D description of oscillating soliton stars. When the amplitude reaches a critical threshold, certain divergences occur which we interpret as signal of horizon formation. …”

Mass loss and longevity of gravitationally bound oscillating scalar lumps (oscillatons) in D dimensions
Published 2010“…Spherically symmetric oscillatons (also referred to as oscillating soliton stars) i.e. gravitationally bound oscillating scalar lumps are considered in theories containing a massive self-interacting real scalar field coupled to Einstein’s gravity in 1+D dimensional spacetimes. …”

On a Crucial Role of Gravity in the Formation of Elementary Particles
Published 2020-10-01“…We obtain—to our knowledge—for the first time, the discrete spectrum of neutral soliton-like solutions (“mini-boson stars”, “soliton stars”, etc.)…”
