2nd International Workshop on the Frontiers of Nanomechanical Systems (FNS/2019)

第二届纳米机械系统前沿国际研讨会（FNS/2019）将于2019年2月10日至14日在加州棕榈泉举行。 本次研讨会将汇集国际研究界从事研究纳米机械系统，旨在促进思想，方法和技术的交流。这将推动纳米力学的跨学科合作研究，并进一步加速该领域在基础研究和应用方面的进展。研究生和研究助理特别欢迎参加会议。为了吸引他们，有关会议的信息被广泛传播，并要求同事们鼓励他们的学生和博士后参加。已经有32名研究生参加了研讨会，约占整个参与者群体的三分之一。与会者限于110名科学家，以确保整个过程中活跃的互动和充分的参与。其余三分之二的参与者大致分为博士后和高级科学家（教授或专业科学研究人员）。预计从这笔赠款中获得的奖学金将提供给未来的学生和博士后。这将大大增加和加强学生和博士后在研讨会上的参与。已采取步骤鼓励代表性不足的群体成员也参加会议。这一努力的成功的一个衡量标准是，沿着女性受邀演讲者，一名女研究生被选中做口头贡献演讲，这对于一个考虑到会议水平的学生来说是一个难得的机会。FNS/2019研讨会来自纳米机械系统所带来的挑战。它们包括，但不限于，（i）相对较强的量子和经典波动的发生和（ii）振动非线性。沿着热涨落的存在，NEMS也受到非平衡涨落的影响。描述和理解这些波动以及揭示其后果是复杂的，需要开发新的技术。同时，由于系统尺寸小，即使振幅相对较小的振动也会变成非线性的，非线性通常已经对热波动起作用。应对这些挑战需要国际社会的共同努力。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Second International Workshop on the Frontiers of Nanomechanical Systems (FNS/2019) will be held in Palm Springs, California, 10 to 14 February 2019. This workshop will serve to bring together the international research community engaged in studying nanomechanical systems and is intended to promote exchange of ideas, approaches, and techniques. This should advance collaborative, cross-disciplinary research on nanomechanics and further accelerate the progress in the field, both in terms of fundamental studies and applications. Graduate students and research associates are especially welcome at the conference. To attract them, information about the conference was broadly disseminated, and colleagues were asked to encourage their students and postdocs to attend. There are already 32 graduate students participating in the workshop, which is roughly one-third of the entire participant cohort. The participants are limited to 110 scientists to ensure lively interaction and full participation throughout. The remaining two-thirds of the participants are roughly divided equally between postdocs and senior scientists (either professorial faculty, or professional scientific researchers). The scholarships expected from this grant are intended to be provided to prospective students and postdocs. This should significantly increase and enhance the participation of students and postdocs at the workshop. Steps have been taken to encourage members of the underrepresented groups to attend as well. A measure of success of this effort is that, along with female invited speakers, a female graduate student has been chosen to give an oral contributed talk, which is an exceptional opportunity for a student given the level of the conference.The workshop FNS/2019 comes from the challenges that are posed by nanomechanical systems. They include, but are not limited to, (i) the occurrence of comparatively strong quantum and classical fluctuations and (ii) the vibration nonlinearity. Along with the invariably present thermal fluctuations, NEMS are subject to nonequilibrium fluctuations. Characterizing and understanding these fluctuations, as well as revealing their consequences is complicated and requires developing new techniques. At the same time, because of the small system size, vibrations with even comparatively small amplitudes become nonlinear, with the nonlinearity often coming into play already for thermal fluctuations. Addressing these challenges requires concerted international effort.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
