Renormalization group for treating 2D coupled arrays of continuum 1D systems
1CMPMS Department, Brookhaven National Laboratory, Upton, New York 11973, USA.
Abstract:
We study the spectrum of two dimensional coupled arrays of continuum one-dimensional systems by wedding a density matrix renormalization group procedure to a renormalization group improved truncated spectrum approach. To illustrate the methodology, we study the spectrum of large arrays of coupled quantum Ising chains. We demonstrate explicitly that the method can treat the various regimes of chains, in particular, the three dimensional Ising ordering transition the chains undergo as a function of interchain coupling.

Couples: Scalar and Vector Formulation
A couple moment is a rotational force that tends to rotate the steering wheel. The wheel's rotation can either be in a clockwise or anticlockwise direction. The right-hand rule is a helpful method for determining the direction of a couple moment. To...
