  • Asymptotic solvability of an imaginary cubic oscillator with spikes 
    Znojil, Miloslav; Gemperle, Frantisek; Mustafa, Omar (IOP Publishing, 2002)
    For complex potentials V(x) = -(ix)(3) -beta(2)(ix)(-2) - 2betadelta(ix)(1/2) which are PT symmetric, we show that in beta much greater than 1 strong coupling regime the low-lying bound states almost coincide with harmonic ...
