Single Particle Hopping Between Luttinger Liquids: A Spectral Function Approach
We present a pedagogical account of our approach to the problem of Luttinger liquids coupled by interliquid single particle hopping. It is shown that the key issue is that of coherence/incoherence of interliquid hopping, and not of relevance/irrelevance in a renormalization group sense. A clear signal of coherence, present in the case of coupled Fermi liquids, is absent for Luttinger liquids, a...
متن کاملFaddeev description of two-hole–one-particle motion and the single-particle spectral function
The Faddeev technique is employed to address the problem of describing the influence of both particleparticle and particle-hole phonons on the single-particle self-energy. The scope of the few-body Faddeev equations is extended to describe the motion of two-hole–one-particle ~two-particle–one-hole! excitations. This formalism allows one to sum both particle-particle and particle-hole phonons, o...
متن کاملSpectral Scattering Imaging for Single Particle Detection and Size Discrimination
We investigate an optical imaging technique which is capable of detecting and size discriminating single nanoparticles which are below the diffraction limited resolution. Our technique employs wide-field detection and processing of interferometric signal due to the elastically scattered light and reference light at different visible wavelengths. The simulation and experimental results prove the...
متن کاملSingle particle high resolution spectral analysis flow cytometry.
BACKGROUND While conventional multiparameter flow cytometers have proven highly successful, there are several types of analytical measurements that would benefit from a more comprehensive and flexible approach to spectral analysis including, but certainly not limited to spectral deconvolution of overlapping emission spectra, fluorescence resonance energy transfer measurements, metachromic dye a...
متن کاملHole spectral function and two-particle-one-hole response propagator.
The fragmentation of one-nucleon knock-out strength at low energies is considered from the viewpoint of the two particle-one hole ~and two holeone particle! response propagator. The aim is to deal with particleparticle ~and hole-hole! as well as particle-hole collectivity simultaneously. This is achieved on a TammDancoff level by the so-called Faddeev approximation of the 2p1h propagator. Resul...
