Comment on "Time-Dependent Density-Matrix Renormalization Group: A Systematic Method for the Study of Quantum Many-Body Out-of- Equilibrium Systems"
H. G. Luo, T. Xiang, X. Q. Wang
In a recent Letter [Phys. Rev. Lett. 88, 256403(2002), cond-mat/0109158] Cazalilla and Marston proposed a time-dependent density- matrix renormalization group (TdDMRG) algorithm fo…
CP Violating Rate Difference Relations for and in Broken SU(3)
A. D. Dariescu, N. G. Deshpande, X. -G. He +1
Within the standard model there exist certain relations between CP violating rate differences in B decays in the SU(3) limit. We study SU(3) breaking corrections to these relations…
Tagging the p n -> d phi reaction by backward protons in p d -> d phi p_{sp} processes
L. P. Kaptari, B. Kampfer, S. S. Semikh
The reaction p d -> d phi p_{sp} is studied within the Bethe-Salpeter formalism. Under special kinematical conditions (slow backward spectator proton p_{sp} and fast forward deuter…
Topological Charge of Noncommutative ADHM Instanton
Yu Tian, Chuan-Jie Zhu, Xing-Chang Song
We analytically calculate the topological charge of the noncommutative ADHM U(N) k-instanton using the Corrigan's identity and find that the result is exactly the instanton number…
Non-minimally Coupled Tachyon and Inflation
Yun-Song Piao, Qing-Guo Huang, Xinmin Zhang +1
In this paper, we consider a model of tachyon with a non-minimal coupling to gravity and study its cosmological effects. Regarding inflation we will show that for a specific coupli…
Scaling and nonscaling finite-size effects in the Gaussian and the mean spherical model with free boundary conditions
X. S. Chen, V. Dohm
We calculate finite-size effects of the Gaussian model in a L\times \tilde L^{d-1} box geometry with free boundary conditions in one direction and periodic boundary conditions in d…
