Catalyzing New International Collaboration: US-Singapore collaborative initial data gathering activities on mechanics of quantum and semi-classical conductors

这个美国-新加坡项目将促进PI在纽约州立大学布法罗分校的实验小组和新加坡南洋理工大学的理论小组之间的新的国际合作。在PI团队访问新加坡期间，PI最近关于小到单原子桥的原子尺寸导体的机械稳定性的实验结果将从理论上进行分析，重点关注费米长度尺度下模量增强和变形模式的尺寸依赖性。这将为理解晶体结构和原子配位、温度和表面能对原子尺寸样品稳定性的作用的长期目标奠定基础。学生参与这项活动将有助于发展他们的能力，以适应实验和理论方法。该项目将有助于建立一个理论和定量框架来解释量子和半经典导体的力学。

This US-Singapore project will catalyze a new international collaboration between the PI's experimental group at SUNY-Buffalo and a theoretical group at the Nanyang Technological University in Singapore. During the PI's team visit to Singapore, the PI's recent experimental results on mechanical stability of atomic-sized conductors as small as a single-atom bridge will be analyzed theoretically, focusing on the size dependence of the modulus enhancement and deformation modes at the Fermi length scale. This will lay the foundation for the longer term objective of understanding the role of crystal structure and atomic coordination, temperature, and surface energy, on the stability of atomic-sized samples. Involvement of students in this activity will help to develop their capacities to be comfortable with both experimental and theoretical approaches. The project will help establish a theoretical and quantitativeframework to explain the mechanics of quantum and semi-classical conductors.
