Abstract

We have investigated analytically and numerically the liquid-glass transition of hard spheres for dimensions dd\to \infty in the framework of mode-coupling theory. The numerical results for the critical collective and self nonergodicity parameters fc(k;d)f_{c}(k;d) and fc(s)(k;d)f_{c}^{(s)}(k;d) exhibit non-Gaussian kk -dependence even up to d=800d=800. fc(s)(k;d)f_{c}^{(s)}(k;d) and fc(k;d)f_{c}(k;d) differ for kd1/2k\sim d^{1/2}, but become identical on a scale kdk\sim d, which is proven analytically. The critical packing fraction ϕc(d)d22d\phi_{c}(d) \sim d^{2}2^{-d} is above the corresponding Kauzmann packing fraction ϕK(d)\phi_{K}(d) derived by a small cage expansion. Its quadratic pre-exponential factor is different from the linear one found earlier. The numerical values for the exponent parameter and therefore the critical exponents aa and bb depend on dd, even for the largest values of dd.
