Surprising spectra of PT -symmetric point interactions

چکیده

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 self-adjoint case despite of PT -symmetry, P-pseudo-Hermiticity and T -self-adjointness.

Exactly Solvable Many-Body Systems and Pseudo-Hermitian Point Interactions

The complex generalization of conventional quantum mechanics has been investigated extensively in recent years. In particular it is shown that the standard formulation of quantum mechanics in terms of Hermitian Hamiltonians is overly restrictive and a consistent physical theory of quantum mechanics can be built on a complex Hamiltonian that is not Hermitian but satisfies the less restrictive an...

On Integrability and Pseudo-Hermitian Systems with Spin-Coupling Point Interactions

We study the pseudo-Hermitian systems with general spin-coupling point interactions and give a systematic description of the corresponding boundary conditions for PT-symmetric systems. The corresponding integrability for both bosonic and fermionic many-body systems with PT-symmetric contact interactions is investigated.

Biophysical and Molecular Docking Studies of Human Serum Albumin Interactions with a Potential Anticancer Pt(II) Complex

The interaction between [Pt(phen)(pyrr-dtc)]NO3 (where phen = 1,10-phenanthroline and pyrr-dtc =pyrrolidinedithiocarbamat) with human serum albumin (HSA) was studied by fluorescence, UV–vis absorption, circular dichroism (CD) spectroscopy and molecular docking technique under like physiological condition in Tris–HCl buffer solution at pH 7.4. UV-Vis absorption spectroscopy indicates that the pro...

(1+1)-Dirac particle with position-dependent mass in complexified PT -symmetric Lorentz scalar interactions

The effect of the built-in supersymmetric quantum mechanical language on the spectrum of the (1+1)-Dirac equation, with position-dependent mass (PDM) and complexified Lorentz scalar interactions, is re-emphasized. The signature of the ”quasi-parity” on the Dirac particles’ spectra is also studied. A Dirac particle with PDM and complexified scalar interactions of the form S (z) = S (x− ib) (an i...
