密度矩阵重整化群 meaning in English

density matrix renormalization group

It is just the difficulty that the strongly correlated electron systems can not be studied by analytical methods , a variety of simulative numerical methods come out sequentially . there are a few typical methods such as the exact diagonalization ( ed ) , the qutum monte carlo ( qmc ) , the variation monte carlo ( qmc ) , the renormalization group ( rg ) , and the density matrix renormalization group ( dmrg ) and so on
正是强关联系统遇到了解析研究的困难，各种数值模拟方法才相继出现，最典型的数值方法有：严格对角化( ed ) ，量子蒙特卡洛( qmc )模拟、变分蒙特卡洛模拟( vmc ) 、数值重整化群( rg )以及密度矩阵重整化群( dmrg )等。
