Paramagnetic state in d-wave Superconductors

We study theoretically the paramagnetic state in d-wave superconductors. We present the specific heat, the magnetization, superfluid density obtained within the weak-coupling model. At low temperatures and for small magnetic fields they exhibit simple power law behaviors, which should be accessible experimentally in hole-doped high-T_c cuprates and \kappa-(ET)_2 salts in a magnetic field within the conducting plane.Comment: 5 pages(EuroTeX), 13 figures, submitted to Europhysics Letter

Bremsstrahlung Radiation At a Vacuum Bubble Wall

When charged particles collide with a vacuum bubble, they can radiate strong electromagnetic waves due to rapid deceleration. Owing to the energy loss of the particles by this bremsstrahlung radiation, there is a non-negligible damping pressure acting on the bubble wall even when thermal equilibrium is maintained. In the non-relativistic region, this pressure is proportional to the velocity of the wall and could have influenced the bubble dynamics in the early universe.Comment: 6 pages, 2 figures, revtex, to appear in JKP

‘My Business is All About Love and Care’: Korean Female Immigrant Entrepreneurship in Sydney

This paper reports on a study of Korean immigrant women to examine various personal, social, economic and cultural aspects of their entrepreneurial activities in Australia. Based on in-depth interviews, findings suggest that women’s decision to start business was greatly affected by a complex interaction between push and pull factors; that their performance in the business were often constrained by a lack of support and resources as well as traditional gender role; and that doing business empowered the women, helping improve financial, social and/or psychological independence. These findings, although generated from a small sample, will contribute to a better understanding of the intersection of gender, ethnicity and entrepreneurship
