Ford C, Bender C, Hassanpour N, et al., 2018, Series solutions of PT -symmetric Schrödinger equations, Journal of Physics Communications, Vol: 2, ISSN: 2399-6528
A simple and accurate numerical technique for finding eigenvalues, node structure, and expectation values of ${ \mathcal P }{ \mathcal T }$-symmetric potentials is devised. The approach involves expanding the solution to the Schrödinger equation in series involving powers of both the coordinate and the energy. The technique is designed to allow one to impose boundary conditions in ${ \mathcal P }{ \mathcal T }$-symmetric pairs of Stokes sectors. The method is illustrated by using many examples of ${ \mathcal P }{ \mathcal T }$-symmetric potentials in both the unbroken- and broken-${ \mathcal P }{ \mathcal T }$-symmetric regions.

Bender CM, Hassanpour N, Hook DW, et al., 2017, Behavior of eigenvalues in a region of broken PT symmetry, Physical Review A, Vol: 95, ISSN: 1050-2947
PT-symmetric quantum mechanics began with a study of the Hamiltonian H=p2+x2(ix)ɛ. When ɛ≥0, the eigenvalues of this non-Hermitian Hamiltonian are discrete, real, and positive. This portion of parameter space is known as the region of unbroken PT symmetry. In the region of broken PT symmetry, ɛ<0, only a finite number of eigenvalues are real and the remaining eigenvalues appear as complex-conjugate pairs. The region of unbroken PT symmetry has been studied but the region of broken PT symmetry has thus far been unexplored. This paper presents a detailed numerical and analytical examination of the behavior of the eigenvalues for −4<ɛ<0. In particular, it reports the discovery of an infinite-order exceptional point at ɛ=−1, a transition from a discrete spectrum to a partially continuous spectrum at ɛ=−2, a transition at the Coulomb value ɛ=−3, and the behavior of the eigenvalues as ɛ approaches the conformal limit ɛ=−4.

Bender CM, Hook DW, Mavromatos NE, et al., 2016, PT-symmetric interpretation of unstable effective potentials, Journal of Physics A: Mathematical and Theoretical, Vol: 49, ISSN: 1751-8113
The conventional interpretation of the one-loop effective potentials of theHiggs field in the Standard Model and the gravitino condensate in dynamicallybroken supergravity is that these theories are unstable at large field values.A PT-symmetric reinterpretation of these models at a quantum-mechanical leveleliminates these instabilities and suggests that these instabilities may alsobe tamed at the quantum-field-theory level.

In a remarkable paper Chandrasekar et al. showed that the (second-order constant-coefficient) classical equation of motion for a damped harmonic oscillator can be derived from a Hamiltonian having one degree of freedom. This paper gives a simple derivation of their result and generalizes it to the case of an nth-order constant-coefficient differential equation.
