Tracking down localized modes in PT-symmetric Hamiltonians under the influence of a competing nonlinearity [PDF]
, 2014 The relevance of parity and time reversal (PT)-symmetric structures in optical systems is known for sometime with the correspondence existing between the Schrodinger equation and the paraxial equation of diffraction where the time parameter represents ...

Variational approach to a class of nonlinear oscillators with several limit cycles [PDF]
, 2001 We study limit cycles of nonlinear oscillators described by the equation $\ddot x + \nu F(\dot x) + x =0$. Depending on the nonlinearity this equation may exhibit different number of limit cycles.

Complex Extension of Quantum Mechanics [PDF]
, 2002 It is shown that the standard formulation of quantum mechanics in terms of Hermitian Hamiltonians is overly restrictive. A consistent physical theory of quantum mechanics can be built on a complex Hamiltonian that is not Hermitian but satisfies the less ...

A method for solving systems of non-linear differential equations with moving singularities [PDF]
, 2002 We present a method for solving a class of initial valued, coupled, non-linear differential equations with `moving singularities' subject to some subsidiary conditions.

Complex Lagrangians and phantom cosmology [PDF]
, 2006 Motivated by the generalization of quantum theory for the case of non-Hermitian Hamiltonians with PT symmetry, we show how a classical cosmological model describes a smooth transition from ordinary dark energy to the phantom one.
