LaGa-based bulk metallic glasses

Linzhi Zhao、Rongjie Xue、Weihua Wang 等 4 位作者2017-01-01Chinese Physics B

We report the formation of LaGa-based bulk metallic glasses. Ternary La–Ga–Cu glassy rods of 2–3 mm in diameter can be easily formed in a wide composition range by the conventional copper mold casting method. With minor addition of extra elements such as Co, Ni, Fe, Nb, Y, and Zr, the critical diameter of the full gla…

OSEFT or how to go beyond hard thermal loops

Cristina Manuel、Joan Soto、Stephan Stetina2017-01-01EPJ Web of Conferences

We show that effective field theory techniques can be applied in the high temperature T regime of plasmas to improve the accuracy of the physics of the hard scales (or scales of order T), and as a by-product, also that of the soft scales (or scales of order gT). At leading order in the coupling constant the hard scale…
