Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Spectral instability of Electronic Euler-Poisson System
电子 Euler-Poisson系统 谱不稳定性
2023/12/11
The focus of this presentation is the spectral (in-)stability of periodic waves for the electronic Euler-Poisson system, a hydrodynamical model for understanding electron dynamics in plasmas. It is fo...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Topological materials: concept, theory, prediction, and detection
拓扑材料 固体物理学 量子霍尔效应
2023/4/17
物理学中许多概念是在不断地发展中的。例如人们对光、电子等的理解与它们刚开始出现时的概念已经发生了许多进化，而固体物理学中的“绝缘体”概念也是如此。近三十年来，量子霍尔效应的相关研究不仅催生了拓扑序这一新的物相分类，也推动了拓扑绝缘体这一新兴研究领域的诞生和发展。随着量子自旋霍尔效应、拓扑晶体绝缘体等工作的后续展开，人们意识到对称性可以带来新的拓扑态，同时也不断地在“普通绝缘体”中发现新的拓扑态。这...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Does qubit connectivity impact quantum circuit complexity
量子比特连接 量子电路 复杂性
2023/4/13
Some physical implementation schemes of quantum computing -- such as those based on superconducting qubits, quantum dots, and cold atoms -- can apply two-qubit gates only on certain pairs of qubits. O...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Equivalence Checking of Quantum Circuits by Nonlocality
量子电路 非局域 等价性检验
2023/4/17
Suppose two quantum circuit chips are located at different places, for which we do not have any prior knowledge, and cannot see the internal structures either. In such a situation, a realistic and fun...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：基于谱形因子的量子混沌与退相干的研究
谱形因子 量子混沌 退相干
2023/5/10
谱形因子的"倾角-斜坡-平台"结构可以反映量子混沌效应的强弱，特别是"斜坡"的展宽是复杂系统能级长程关联的直接体现。本报告主要以随机矩阵和Sachdev-Ye-Kitaev模型为例，介绍我们对于量子混沌与量子退相干之间关系的一些研究进展，包括：1）退相干可以抑制倾角的出现并且缩短与混沌行为相关的线性斜坡的跨度，也就是说退相干可以抑制混沌效应；2）进一步发现在具有平衡增益和损失的非厄米演化过程中却可...
