WitrynaHamiltonian is that the Hamiltonian admits a complete set of bi-orthonormal eigenvectors. Most of the papers have discussed the solution of the Hamiltonian of typeH =p2 +V(x). There are few papers in which the authors have studied the case of the Hamiltonian of the type, H =[p +ξg(x)]2 +V(x), which are very important in quantum … WitrynaWe have investigated the exceptional points (EPs) which are degeneracies of a non-Hermitian Hamiltonian, in the case that three modes are interacting with each other. Even though the parametric evolution of the modes cannot be uniquely determined when encircling more than two EPs once, we can recover the initial configuration of the … elevate pharmacy consultingWitrynaIn this paper, we propose a 1+1D chiral fermion model on 1d spatial lattice, standing alone -- without being associated with a 2d bulk -- with a simple it non-Hermitian hopping Hamiltonian. We demonstrate, using various methods, that the model possesses the same chiral anomaly and gravitational anomaly as in continuum theory. elevate performing arts indianapolis
