Ad hoc physical Hilbert spaces in Quantum Mechanics
(Springer, 2014-10-21)
The overall principles of what is now widely known as PT-symmetric quantum mechanics are listed, explained and illustrated via a few examples. In particular, models based on an elementary local interaction V(x) are discussed ...
Soluções exatas das equações de Einstein com simetria axialExact solutions to the Einstein equations with axial symmetry

Interplay of disorder and PT symmetry in one-dimensional optical lattices
(American Physical Society, 2015)
We study a one-dimensional binary optical lattice in the presence of diagonal disorder and alternating gain
and loss, and examine the light transport phenomena for localized and extended input beams. In the pure
PT ...
Symmetric quadratic Hamiltonians with pseudo-Hermitian matrix representation
(Academic Press Inc Elsevier Science, 2016-06)
We prove that any symmetric Hamiltonian that is a quadratic function of the coordinates and momenta has a pseudo-Hermitian adjoint or regular matrix representation. The eigenvalues of the latter matrix are the natural ...
