Hole 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...
متن کاملCombinatorial Properties of One-Dimensional Arrangements
Arrangements are an omni-present topic in computational geometry, since many problems in computer graphics and robotics reduce to the study of such sets. Motivated by two problems from these areas —more precisely from ray-tracing and assembly planning, we study in this paper the combinatorial structure of arrangements of segments on a line and of cones on a circle. We show that the numbers of s...
متن کاملOne-dimensional Quantum Spin Liquids
This chapter is intended as a brief overview of some of the quantum spin liquid phases with unbroken SU(2) spin symmetry available in one dimension. The main characteristics of these phases are discussed by means of the bosonization approach. A special emphasis is laid on the interplay between frustration and quantum fluctuations in one dimension.
متن کاملDecay of spin coherences in one-dimensional spin systems
Strategies to protect multi-qubit states against decoherence are difficult to formulate because of their complex many-body dynamics. A better knowledge of the decay dynamics would help in the construction of dynamical decoupling control schemes. Here we use solid-state nuclear magnetic resonance techniques to experimentally investigate decay of coherent multi-spin states in linear spin chains. ...
متن کاملSpectral Deformations of One-dimensional Schrödinger Operators
We provide a complete spectral characterization of a new method of constructing isospectral (in fact, unitary) deformations of general Schrödinger operators H = − d2 dx2 + V in L2(R). Our technique is connected to Dirichlet data, that is, the spectrum of the operator HD on L2((−∞, x0))⊕L2((x0 ,∞)) with a Dirichlet boundary condition at x0. The transformation moves a single eigenvalue of HD and ...
