Critical point of a weakly interacting two-dimensional Bose gas.
We study the Berezinskii-Kosterlitz-Thouless transition in a weakly interacting 2D quantum Bose gas using the concept of universality and numerical simulations of the classical absolute value psi(4) model on a lattice. The critical density and chemical potential are given by relations n(c) = (mT/2piPlanck's(2))ln(xiPlanck's(2)/mU) and mu(c) = (mTU/piPlanck's(2))ln(xi(mu)Planck's(2)/mU), where T...
متن کاملCritical temperature of Bose-Einstein condensation for weakly interacting bose gas in a potential trap
The critical temperature of Bose-Einstein condensation at minimum momentum state for weakly interacting Bose gases in a power-law potential and the deviation of the critical temperature from ideal bose gas are studied. The effect of interaction on the critical temperature is ascribed to the ratiao α/λc, where α is the scattering length for s wave and λc is de Broglie wavelength at critical temp...
متن کاملCritical behavior of a four-point Schwinger-Dyson equation.
We study the Schwinger-Dyson equation associated with a chirality-changing fermion 4-point function in a strongly-coupled U(1) gauge theory. After making appropriate simpliications, we solve the equation numerically via a relaxation method. Our analysis provides an estimate of the critical coupling and it gives some indication as to the general momentum dependence of the 4-point function.
متن کاملExact renormalization group equation for the Lifshitz critical point
An exact renormalization equation (ERGE) accounting for an anisotropic scaling is derived. The critical and tricritical Lifshitz points are then studied at leading order of the derivative expansion which is shown to involve two differential equations. The resulting estimates of the Lifshitz critical exponents compare well with the O ( ǫ2 ) calculations. In the case of the Lifshitz tricritical p...
متن کاملSolutions of diffusion equation for point defects
An analytical solution of the equation describing diffusion of intrinsic point defects in semiconductor crystals has been obtained for a one-dimensional finite-length domain with the Robin-type boundary conditions. The distributions of point defects for different migration lengths of defects have been calculated. The exact analytical solution was used to verify the approximate numerical solutio...
