Droplet States in the XXZ Heisenberg Chain
We consider the ground states of the ferromagnetic XXZ chain with spin up boundary conditions in sectors with a fixed number of down spins. This forces the existence of a droplet of down spins in the system. We find the exact energy and the states that describe these droplets in the limit of an infinite number of down spins. We also prove that the droplet states, which were known to be separate...
متن کامل20 09 Heisenberg - Lorentz Quantum Group
In this article we present a new deformation of SL(2,C) on the C∗-algebra level. The method of its construction is the Rieffel deformation. We give a detailed description of so obtained a quantum group (A,∆) in terms of affiliated elements α̂, β̂, γ̂, δ̂ ∈ A generating A. In order to construct β̂, we split A onto parts on which β̂ can easily be defined and then show that gluing procedure can be perfo...

متن کاملModified Quantum Renormalization Group for xxz spin chain
A simple modification of the standard Renormalization Group (RG) technique for the study of quantum spin systems is introduced. By applying this method to the xxz spin 1 2 Heisenberg chain, we obtain the ground state energy with much higher accuracy than the standard RG.
متن کاملA Modified Quantum Renormalization Group for xxz Spin Chain
A simple modification of the standard Renormalization Group (RG) technique for the study of quantum spin systems is introduced. Our method which takes into account the effect of boundary conditions by employing the concept of superblock, may be regarded as a simple way for obtaining first estimates of many properties of spin systems. By applying this method to the xxz spin 1 2 Heisenberg chain,...
