New physics study findings recently were reported by researchers at Kyoto University

  2008 NOV 24 - (VerticalNews.com) -- "We propose a density matrix renormalization group (DMRG) technique at finite temperatures," researchers in Kyoto, Japan report.

  "As is the case of the ground-state DMRG, we use a single-target state that is calculated by making use of a regulated polynomial expansion. Both static and dynamical quantities are obtained after a random-sampling and averaging procedure," wrote S. Sota and colleagues, Kyoto University.

  The researchers concluded: "We apply this technique to the one-dimensional Hubbard model at half filling and find that this gives excellent results at low temperatures."

  Sota and colleagues published their study in Physical Review B (Low-temperature density matrix renormalization group using regulated polynomial expansion. Physical Review B, 2008;78(11):3101).
