Boundary elds and renormalization group owin the two

چکیده
We analyze the Ising model on a random surface with a boundary magnetic eld using matrix model techniques. We are able to exactly calculate the disk amplitude, boundary magnetization and bulk magnetization in the presence of a boundary eld. The results of these calculations can be interpreted in terms of renormalization group ow induced by the boundary operator. In the continuum limit this RG ow corresponds to the ow from non-conformal to conformal boundary conditions which has recently been studied in at space theories.

Time-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
متن کاملOne-loop Renormalization of the Qcd Schrr Odinger Functional
In a previous publication, we have constructed the Schrr odinger functional in Wil-son's lattice QCD. It was found that the naive continuum limit leads to a well-deened classical continuum theory. Starting from the latter, a formal continuum deenition of the Schrr odinger functional is given and its saddle point expansion is carried out to one-loop order of perturbation theory. Dimensional regu...
متن کاملA numerical renormalization group approach for calculating the spectrum of a vibronic system occurring in molecules or impurities in insulators
Theoretically, in order to describe the behavior of a spectrum, a mathematical model whichcould predict the spectrum characteristics is needed. Since in this study a Two-state system has beenused like models which was introduced previously past and could couple with the environment, theformer ideas have been extended in this study. we use the second quantized version for writing thisHamiltonian...
متن کاملRenormalization Group Ow and Xed Point of the Lattice Topological Charge in the 2{d O(3) {model Typeset Using Revt E X 2
We study the renormalization group evolution up to the xed point of the lattice topological susceptibility in the 2{d O(3) non{linear {model. We start with a discretization of the continuum topological charge by a local charge density, polynomial in the lattice elds. Among the diierent choices we propose also a Symanzik{improved lattice topological charge. We check step by step in the renormali...
متن کاملDetermining the Likelihood of Damage in Concrete and its Physical Structure
Applying renormalization group theory to evaluate the safety of overall structure, local damage probability must be obtained at first. According to the results of unit detection test and numerical simulation, the methods how to determine local damage probability was presented in the paper. For small unit, meaning the unit size is far less than the maximum primitive cell or the structure size, i...
