Observation of an accidental bound state in the continuum in a chain of dielectric disks
M. S. Sidorenko, O. N. Sergaeva, Z. F. Sadrieva +4
Being a general wave phenomenon, bound states in the continuum (BICs) appear in acoustic, hydrodynamic, and photonic systems of various dimensionalities. Here, we report the first…
Chaotic and regular dynamics in the three-site Bose-Hubbard model
A. A. Bychek, P. S. Muraev, D. N. Maksimov +1
We analyze the energy spectrum of the three-site Bose-Hubbard model. It is shown that this spectrum is a mixture of the regular and irregular spectra associated with the regular an…
The open Bose-Hubbard chain: Pseudoclassical approach
A. A. Bychek, P. S. Muraev, D. N. Maksimov +1
We analyze stationary current of bosonic carriers in the Bose-Hubbard chain of length where the first and the last sites of the chain are attached to reservoirs of Bose particl…
Probing Quantum Chaos in many-body quantum systems by the induced dissipation
Anna A . Bychek, Pavel S. Muraev, Andrey R. Kolovsky
We theoretically analyze the depletion dynamics of an ensemble of cold atoms in a quasi one-dimensional optical lattice where atoms in one of the lattice sites are subject to decay…
