Note on Angular Momentum of Phonons in Chiral Crystals

Phonon angular momentum in chiral materials has been widely studied in spintronics and condensed matter physics. In chiral crystals, this is not the conserved quantity in contrast to the pseudo-angular momentum. To highlight this point and to understand the behavior of the angular momentum, we reexamined phonon dispersion theory based on the irreducible representation of helix and found the distinction of these angular momentum is originated from chirality.Comment: 2 pages, 2 figure

"Public Debt and Economic Growth in an Aging Japan"

This@paper@examines@the@effects of the demographic change and the government debt policy in Japan on economic growth and economic welfare, particularly by taking into account the existing public pension scheme as well as national medical expenditure through the existing public health insurance, wherea computational overlapping generations model is used within a general equilibrium context. One of the main results of this paper is that the tax burden (GDP) ratio will increase up to about 36%, and the social security burden (GDP) ratio will increase up to 23.3% in 2050, even though the government tries to have a positive primary balance by 2010. The ratio of public health insurance bene?ts to GDP is expected to increase at 1% every 10years, and the ratio will be around 9.6%in 2050. The 2004 public pension reform will successfully result in a 13 point decrease in the contribution rate from 36.44% to 23.53%, and reduce the social security burden (GDP) ratio by about 8 points from 23.27% to 15.02% in 2050, compared with the benchmark case.
