Energy Levels for Nonsymmetric Double-Well Potentials in Several Dimensions: Hill Determinant Approach

Spin–orbit interaction and magnetic field effects on the energy dispersion of double quantum wire

“…This potential has been used to explain the many physical phenomena such as tunneling and doublet splitting by using quantum mechanical or semi-classical methods [2][3][4][5][6][7]. In these studies, usually WKB approximation, variational perturbation method etc.…”

“…In contrast, double-well potentials in multidimensional space have not received so much attention although some progress has been made in calculating their energy eigenvalues [16][17][18][19].…”
