物理学院“锶光钟”研究团队荣获“2022中国光学十大进展”提名奖
4月20日晚，由中国激光杂志社、杭州光学精密机械研究所和杭州市富阳区人民政府联合主办的2023中国光学十大进展高峰论坛暨颁奖典礼在杭州富阳隆重举行。由于成果本身突出的学术水平，以及评审专家的严格公正，这一奖项已经在学术界被广泛认可，成为光学领域最受关注的年度盛典。重庆大学物理学院与重庆大学量子材料与器件研究中心汪涛，张学锋研究团队和国家授时中心“巴渝学者”常宏研究团队合作的“首次实现非重力压制下的锶... April 28, 2023 -
Towards Outer Space: Shaking the Optical Lattice Clock
When travelling in outer space, what is necessary equipment for you? The answer should be an extremely accurate clock, which is useful for checking time and navigation. Then, the best candidate should be optical lattice clock – the most accurate time-frequency measurement device [1].With help of the laser cooling technique, the ultra-cold atom can be trapped in the optical lattice constructed...

‘Battle Ropes’ in the optical lattice clock
The usage of battle ropes is highly related to the relative phase between two waves, such as alternative and double ways. Similarly, researchers doubly modulate one of the most accurate platforms – optical lattice clock [1], and observe the relative phase can strongly affect the ultra-cold quantum systems.[2] The Strontium atoms are cooled down to 3 micro-Kelvins and trapped in the optical lat...

Prof. Rui Wang proposed a novel quantum states in topological phonon systems(published on Phys.Rev.Lett).
On 10 March 2020, the top physical journal Physical Review Letters published the research work lead by Rui Wang, et.al [Phys. Rev. Lett. 124, 105303 (2020)]. Their work proposed a novel quantum states in topological phonon systems, termed as “Symmetry-Protected Topological Triangular Weyl Complex”. Distinct from conventional Weyl systems with Weyl points appearing in pairs, a symmetry-protect... March 27, 2021
