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

小行星9512798 这个美国-巴西的合作研究工作将研究某些不平衡系统的动力学特性，特别是相变的非平衡动力学以及孤立子和涡旋的传输现象。 匹兹堡大学的丹尼尔·博亚诺夫斯基和里约热内卢联邦大学的卡洛斯·阿拉冈·德卡瓦略之间的合作将集中在系统的实时描述上，包括再加热和热化的动态。 这项工作还将扩展到隧道和热激活，开发可应用于凝聚态，粒子物理学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，涉及若干重叠领域的关切问题。这项合作在巴西得到了CNPq的支持，双方将在研究和旅行中包括研究生和博士后。 来访的高级科学家将与研究生互动，提供特殊的教育经验。 ****

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. ****
