ABOUT DEBORAH'S WORK
Deborah Jin is a physicist who uses recent advances in atomic cooling to study the behavior of atoms near absolute zero. As a postdoctoral fellow, Jin participated in early demonstrations of Bose-Einstein condensation—a process in which a small number of atoms become so cold that they collapse into a single quantum state, effectively becoming a giant atom. More recently, Jin has led efforts to apply laser cooling and magnetic trapping techniques to explore the properties of super-cooled fermions, which cannot form Bose-Einstein condensates due to quantum mechanical constraints; attempting to force fermions to a minimal temperature results in a set of atoms in a stack of quantized energy states. Jin made early and critical advances toward reliable experimental production of this minimum temperature state—the degenerate fermi gas. This protocol has importance beyond experimental novelty; in theory, fermions at the higher energy states of a degenerate gas should form Cooper pairs, as electrons do in superconductive materials. The phenomenon has not yet been demonstrated in the laboratory, but doing so will represent an important advance in condensed matter physics. Through a combination of strong theoretical background and remarkable experimental innovation, Jin has provided the field the first giant step towards reaching this milestone.

BIOGRAPHY
Deborah Jin received an A.B. (1990) from Princeton University and a Ph.D. (1995) from the University of Chicago. She was a research associate with the National Institute of Standards (NIST) and Technology from 1995-1997. Since 1997, Jin has held the positions of NIST Physicist, Fellow of JILA and Assistant Professor Adjoint with the University of Colorado, Boulder.

关于黛博拉的工作
金秀兰是一位物理学家,她利用原子冷却的最新进展来研究接近绝对零度的原子的行为。作为一名博士后研究员,金参与了早期的玻色-爱因斯坦凝结的演示--在这个过程中,少量的原子变得如此之冷,以至于它们坍缩成一个单一的量子态,有效地成为一个巨大的原子。最近,金领导了应用激光冷却和磁捕集技术来探索超冷费米子的特性,由于量子力学的限制,这些费米子不能形成玻色-爱因斯坦凝聚;试图迫使费米子达到最低温度的结果是一组原子处于量子化的能量状态堆中。在可靠地实验生产这种最低温度状态--退化费米气体方面,金取得了早期和关键的进展。这个协议的重要性超出了实验的新颖性;在理论上,处于退化气体较高能量状态的费米子应该形成库珀对,就像电子在超导材料中那样。这一现象尚未在实验室中得到证实,但这样做将代表着凝聚态物理学的一个重要进步。通过强大的理论背景和卓越的实验创新相结合,金为该领域提供了达到这一里程碑的第一个巨大步骤。

个人简历
金秀兰在普林斯顿大学获得学士学位(1990年),在芝加哥大学获得博士学位(1995年)。1995-1997年,她是美国国家标准与技术研究所(NIST)的研究助理。自1997年以来,金正恩担任NIST物理学家、JILA研究员和科罗拉多大学博尔德分校助理教授的职务。
