U.S.-Brazil Collaborative Research: Non-Equilibrium Aspects of Quantum Field Systems

这个美国和巴西的合作研究项目将研究某些非平衡系统的动态特性；特别是，相变的非平衡动力学和孤子和涡旋的输运现象。匹兹堡大学的Daniel Boyanovsky和里约热内卢联邦大学的Carlos Aragao de Carvalho的合作将专注于系统的实时描述，包括再加热和热化的动力学。这项工作还将扩展到隧道和热激活，开发可应用于凝聚态物质、粒子物理和宇宙学中的成核和量子隧道的方法。拟议的工作是及时和创新的，解决了几个重叠领域的关切问题。此次合作在巴西得到了CNPq的支持，双方都将有研究生和博士后参与研究和旅行。来访的资深科学家将与研究生互动，提供特殊的教育体验。* * * *

9512798 Boyanovsky This U.S.-Brazil collaborative research effort will study dynamic properties of certain systems out of equilibrium; in particular, the non-equilibrium dynamics of phase transitions and transport phenomena of solitons and vortices. The collaboration between Daniel Boyanovsky of the University of Pittsburgh and Carlos Aragao de Carvalho of Universidade Federal do Rio de Janeiro will focus on real-time descriptions of the systems, including the dynamics of reheating and thermalization. The work will also extend to tunneling and thermal activation, developing methods that can be applied to nucleation and quantum tunneling in condensed matter, particle physics, and cosmology. The proposed work is timely and innovative, addressing issues of concern in several overlapping fields. The collaboration is supported in Brazil by CNPq, and both sides will include graduate students and post-docs in the research and travel. The visiting senior scientists will interact with graduate students to provide special educational experiences. ****
