Trapped-Ion Quantum Simulation of Chemical Dynamics beyond Born-Oppenheimer
时 间：10:00-10:45, Jul 24, 2026 (Fri)地 点：RM 1-222, FIT Building内容：Understanding how molecular vibrations afiect charge and energy transfer in complex chemical and biological systems requires modeling the interactions among the electronic, spin, and vibrational degrees of freedom, which cannot be treated independently, especially when the Born-Oppenheimer approximation breaks down. Tr...

On Minimax Exponents of Sparse Submatrix Detection
时 间：13:30-15:00, Jul 15, 2026 (Wed)地 点：RM 1-222, FIT Building内容：We consider the exact asymptotics of the minimax risk for detecting an elevated-mean sparse submatrix in a large Gaussian random matrix. Although there exists a precise characterization of when and how asymptotic consistency is possible for such testing problems, there is limited understanding of the exact minimax risk...

Towards Trustworthy Cooperative AI: Simulating, Aligning, and Constraining Multi-Agent Systems
时 间：15:00-16:00, Jul 9, 2026 (Thu)地 点：RM 1-202, FIT Building内容：As AI systems increasingly operate as autonomous agents, intelligence is becoming inherently social. Future AI systems will not act in isolation, but will learn, coordinate, communicate, and make decisions alongside humans and other agents in open-ended environments. This shift raises fundamental challenges: How can age...

Recent Advances in Fast Graph Algorithms: Combinatorial Techniques for Path and Flow Problems
时 间：14:00-15:00, Jun 29, 2026 (Mon)地 点：RM 1-222, FIT Building内容：We will discuss recent algorithmic advances for fundamental graph problems, including negative-weight shortest paths, maximum flow, and minimum-cost flow. Classical textbook-style algorithms, such as Bellman-Ford and push-relabel, often lead to \(O(mn)\)-type running times. In recent years, however, there has been trem...
