Abstract. We solved numerically the implicit, trascendental equation that defines the eigenenergy surface of a degenerating isolated doublet of unbound states in the simple but illustrative case of the scattering of a beam of particles by a double barrier potential. Unfolding the degeneracy point with the help of a contact equivalent approximant, crossings and anticrossings of energies and widt...
متن کاملCoherent states of non-Hermitian quantum systems
We use the Gazeau-Klauder formalsim to construct coherent states of non-Hermitian quantum systems. In particular we use this formalism to construct coherent state of a PT symmetric system. We also describe the construction of coherent states following Klauder’s minimal prescription. e-mail : [email protected] e-mail : [email protected]
متن کاملTopological degeneracy of non-Abelian states for dummies
We present a physical construction of degenerate groundstates of the Moore-Read Pfaffian states, which exhibits non-Abelian statistics, on general Riemann surface with genus g. The construction is given by a generalization of the recent argument [M.O. and T. Senthil, Phys. Rev. Lett. 96, 060601 (2006)] which relates fractionalization and topological order. The nontrivial groundstate degeneracy ...
متن کاملBound States of Non-Hermitian Quantum Field Theories
The spectrum of the Hermitian Hamiltonian 1 2p 2 + 12m 2x2 + gx4 (g > 0), which describes the quantum anharmonic oscillator, is real and positive. The non-Hermitian quantum-mechanical Hamiltonian H = 1 2p 2 + 12m 2x2 − gx4, where the coupling constant g is real and positive, is PT -symmetric. As a consequence, the spectrum ofH is known to be real and positive as well. Here, it is shown that the...
متن کاملOptimal Fluctuations and Tail States of non-Hermitian Operators
A statistical field theory is developed to explore the density of states and spatial profile of ‘tail states’ at the edge of the spectral support of a general class of disordered non-Hermitian operators. These states, which are identified with symmetry broken, instanton field configurations of the theory, are closely related to localized sub-gap states recently identified in disordered supercon...
