报告内容简介：In the last decades, density-matrix renormalization group (DMRG) method shows the power of depicting states of low-dimensional quantum systems in or out of equilibrium with incredible precision. Infinite DMRG, as one of outstanding algorithms, targets the wave function translation invariant by a certain unit-cell in the thermodynamical limit and has been generalized into the application on several 1D and 2D quantum systems.

In this talk, I will first introduce elementary ideas of the conventional DMRG on two aspects: (1) Successfully applications in 1D; (2) Challenge in 2D. Secondly, I will extend our discussion to the infinite DMRG in the thermodynamical limit.
