Journalism Department popup.description2 A new method for construction of multi-dimensional quasi-exactly solvable potentials is proposed. Harmonic oscillator spectrum in the deformed phase space is found. The Dirac equation is solved for Coulomb potential with a given deformation. Three-particle potential for helium-4 is found. Thermodynamic functions of N-boson system are calculated for the hard sphere and Coulomb interactions. Product Description popup.authors popup.nrat_date 2020-04-02 Close
