Abstract Discrete multiparametric 1D quantum well with P T -symmetric long-range boundary conditions is proposed and studied. As a nonlocal descendant of the square well families endowed with Dirac (i.e., Hermitian) and with complex Robin (i.e., non-Hermitian but still local) boundary conditions, the model is shown characterized by the survival of solvability in combination with an enhanced spectral-design flexibility. The solvability incorporates also the feasibility of closed-form…

Quantization of Big Bang in crypto-Hermitian Heisenberg picture
A background-independent quantization of the Universe near its Big Bang singularity is considered using a drastically simplified toy model. Several conceptual issues are addressed. (1) The
Two patterns of PT-symmetry breakdown in a non-numerical six-state simulation
Three-parametric family of non-Hermitian but ${\cal PT}-$symmetric six-by-six matrix Hamiltonians $H^{(6)}(x,y,z)$ is considered. The ${\cal PT}-$symmetry remains spontaneously unbroken (i.e., the


Discrete quantum square well of the first kind
Abstract A new exactly solvable cryptohermitian quantum chain model is proposed and analyzed. Its discrete-square-well-like Hamiltonian with the real spectrum possesses a manifestly non-Hermitian
Solvable non-Hermitian discrete square well with closed-form physical inner product
A new Hermitizable quantum model is proposed in which the bound-state energies are real and given as roots of an elementary trigonometric expression while the wave function components are expressed
Real Spectra in Non-Hermitian Hamiltonians Having PT Symmetry
The condition of self-adjointness ensures that the eigenvalues of a Hamiltonian are real and bounded below. Replacing this condition by the weaker condition of $\mathrm{PT}$ symmetry, one obtains new
Pseudo-Hermitian Quantum Mechanics
A diagonalizable non-Hermitian Hamiltonian having a real spectrum may be used to define a unitary quantum system, if one modifies the inner product of the Hilbert space properly. We give a
Scattering in PT-symmetric quantum mechanics
Abstract A general formalism is worked out for the description of one-dimensional scattering in non-hermitian quantum mechanics and constraints on transmission and reflection coefficients are derived
On the Similarity of Sturm–Liouville Operators with Non-Hermitian Boundary Conditions to Self-Adjoint and Normal Operators
We consider one-dimensional Schrödinger-type operators in a bounded interval with non-self-adjoint Robin-type boundary conditions. It is well known that such operators are generically conjugate to
Entanglement and spin squeezing in non-Hermitian phase transitions.
The non-Hermitian Lipkin-Meshkov-Glick model is considered and it is shown that its phase transition occurs with maximum multiparticle entanglement: There is full N-particle entanglements at the transition, in contrast to the Hermitian case.
Scattering from localized non-Hermitian potentials
We highlight the conceptual issues that arise when one applies the quasi-Hermitian framework to analyze scattering from localized non-Hermitian potentials, in particular complex square wells or delta
On the S-matrix of Schrödinger operators with non-symmetric zero-range potentials
Non-self-adjoint Schr?dinger operators which correspond to non-symmetric zero-range potentials are investigated. We show that various properties of (eigenvalues, exceptional points, spectral
Pseudo-Hermitian Representation of Quantum Mechanics
A diagonalizable non-Hermitian Hamiltonian having a real spectrum may be used to define a unitary quantum system, if one modifies the inner product of the Hilbert space properly. We give a
