Preparation of the Phencyclidine Analogues (Part II)
Using a-tetralone, as starting material, a series of phencyclidine analogues were synthesized. This ketone was reacted separately with ethylmagnesium bromide, P-methoxyphenylmagnesium bromide and P-methylphenylmagnesium bromide. The resultant alcohols were treated with a suspension of NaN3 and CCl3COOH in CHCl3. The azides were subsequently...
متن کاملPT −symmetric square well
Below a (comparatively large) measure of non-Hermiticity Z = Z (crit) 0 > 0 of a PT symmetrically complexified square well, bound states are constructed non-numerically. All their energies prove real and continuous in the (Hermitian) limit Z → 0. Beyond the threshold Z (crit) 0 (and, in general, beyond Z (crit) m at m = 0, 1, . . .) the lowest two real energies (i.e., E2m and E2m+1) are shown t...
متن کاملSurprising spectra of PT -symmetric point interactions
Spectra of the second derivative operators corresponding to the special PT -symmetric point interactions are studied. The results are partly the completion of those obtained in [1]. The particular PT -symmetric point interactions causing unusual spectral effects are investigated for the systems defined on a finite interval as well. The spectrum of this type of interactions is very far from the ...
متن کاملDiscrete PT −symmetric square-well oscillators
Exact solvability of the discretized N−point version of the PT −symmetric squarewell model at all N is pointed out. Its wave functions are found proportional to the classical Tshebyshev polynomials Uk cos θ) of a complex argument. A compact secular equation is derived giving the real spectrum of energies at all the non-Hermiticity strengths Z ∈ (−Zcrit(N), Zcrit(N)). In the limit Z → 0 the mode...
متن کاملPT -Symmetric Quantum Field Theory
A new approach to quantum theories was proposed in 1996 in the context of the so-called δ-expansion [1]. The idea was to study non-Hermitian theories which nevertheless possessed positive spectra. Parity symmetry P was broken in these theories, as well as time-reversal invariance T . However, PT symmetry was unbroken. In early papers we examined scalar field theories with interaction [1] Lint =...
