Unitarity of the time-evolution and observability of non-Hermitian Hamiltonians for time-dependent Dyson maps
(Iop Publishing Ltd, 2020-06-01)
We present an strategy for the derivation of a time-dependent Dyson map which ensures simultaneously the unitarity of the time evolution and the observability of the whole time-dependent non-Hermitian Hamiltonian or parts ...

Separation of particles in time-dependent focusing billiards
(Elsevier B.V., 2010-12-01)
We consider a family of stadium-like billiards with time-dependent boundaries. Two different cases of time dependence are studied: (i) the fixed boundary approximation and (ii) the exact model which takes into account the ...

Balance of payments constraints as the key to dependency: the case of Argentina
(SAGE Publications, 2022-01)
Considering the constraints to growth derived from the balance of payments and the external sector as the area in which the dependency of Latin American countries is most clearly expressed, application of the contributions ...
