v 1 2 3 A pr 1 99 3 Impurity - Bond Effect on the Spin - 1 Antiferromagnetic Heisenberg Chain
Low-lying excited states of the spin-1 antiferromagnetic Heisenberg chain with an impurity bond are investigated in terms of domain-wall excitations by means of analytical methods as well as a method of numerical diagonalization. It is shown that 1) the impurity bond brings about a massive triplet mode in the Haldane gap, 2) the triplet state comprises three of the four ground states of an open...
متن کاملJ an 1 99 8 Resonance tunneling of polaritons in 1 - D chain with a single defect
We consider propagation of coupled waves (polaritons) formed by a scalar electromagnetic wave and excitations of a finite one dimensional chain of dipoles. It is shown that a microscopic defect (an impurity dipole) embedded in the chain causes resonance tunneling of the electromagnetic wave with the frequency within the forbidden band between two polariton branches. We demonstrate that resonanc...
متن کاملA pr 1 99 4 Exact thermostatic results for the n - vector model on the harmonic chain
Here H0 is the Hamiltonian for the nearest-neighbor coupled harmonic chain which consists of a one-dimensional lattice lZ with lattice constant l > 0 and a set of N+1 point particles of mass m > 0 distributed along the Euclidean line IR at positions jl + qj , j = 1, 2, . . . , N + 1. The momentum of the j-th particle is denoted by pj and the spring constant of this chain is mω 0. We assume now ...
متن کامل0 v 1 1 1 A pr 1 99 6 Dark pair coherent states of the motion of a trapped ion
We propose a scheme for generating vibrational pair coherent states of the motion of an ion in a two-dimensional trap. In our scheme, the trapped ion is excited bichromatically by three laser beams along different directions in the X-Y plane of the ion trap. We show that if the initial vibrational state is given by a two-mode Fock state, the final steady state, indicated by the extinction of th...
متن کاملField Theory Approach to Quantum Impurity Problems ∗
Quantum impurity problems occur in various areas of physics. Some examples are: an impurity spin in a metal (the Kondo problem), the two-impurity Kondo problem, a defect or impurity spin in a spin chain, tunnelling through a barrier in a quantum wire proton-monopole scattering (the Callan-Rubakov effect). Some common features of these problems are: 1. gapless “bulk” excitations (ie. far from th...
