The dynamical instabilities involve creation of quasiparticle pairs in positive and negative energy states, as in the well-known suggested mechanism for black-hole evaporation. We propose a scheme to generate a stable sonic black hole in a ring trap.engjournal articlehttp://dx.doi.org/10.1103/PhysRevLett.85.4643http://journals.aps.orghttp://arxiv-web2.library.cornell.edu/pdf/gr-qc/0002015.pdfopen access51-73Hawking radiationDark solitonsAtom laserEvaporationVorticesHorizonsCreationHe-3Física-Modelos matemáticosFísica matemática
