This paper presents new classes of exact radial solutions to the nonlinear ordinary differential equation that arises as a saddle-point condition for a Euclidean scalar field theory in D-dimensional spacetime. These solutions are found by exploiting

For any pair of quantum states, an initial state $|I angle$ and afinal quantum state $|F angle$, in a Hilbert space, there are many Hamiltonians $H$ under which $|I angle$ evolves into $|F angle$. Let us impose the constraint that the difference betw

In quantum mechanics the eigenstates of the Hamiltonian form a complete basis. However, physicists conventionally express completeness as a formal sum over the eigenstates, and this sum is typically a divergent series if the Hilbert space is infinite

Non-Hermitian theories that are explicitly PT-symmetric and/or quasi/pseudo-Hermitian have become the subject of an active research field for the last two decades. They constitute well-defined classical and quantum theories possessing real eigenvalue

In a previous paper it was shown how to calculate the ground-state energy density $\mathcal{E}$ and the $p$-point Green's functions ${G}_{p}({x}_{1},{x}_{2},\dots{},{x}_{p})$ for the $\mathcal{PT}$-symmetric quantum field theory defined by the Hamilt

Quantum systems governed by non-Hermitian Hamiltonians with PT symmetry are special in having real energy eigenvalues bounded below and unitary time evolution. We argue that PT symmetry may also be important and present at the level of Hermitian quan

This paper reports the results of an ongoing in-depth analysis of the classical trajectories of the class of non-Hermitian $PT$-symmetric Hamiltonians $H=p^2+ x^2(ix)^\varepsilon$ ($\varepsilon\geq0$). A variety of phenomena, heretofore overlooked, h

Relativistic $\mathcal{PT}$-symmetric fermionic interacting systems are studied in $1+1$ and $3+1$ dimensions. The noninteracting Dirac equation is separately $\mathcal{P}$ and $\mathcal{T}$ invariant. The objective here is to include non-Hermitian $
