1	徐长松	Realistic Spin Model for Multiferroic NiI2	Comprehensive first-principle-based spin Hamiltonians are constructed for the type-II multiferroic NiI2 with application of an invariant expansion method. The model can well reproduce the experimental ground state of canted proper screw that propagate along 〈1-10〉 directions. It is demonstrated that the Kitaev interaction not only strongly contributes to the stabilization of the helical ground state, but also dominantly determines its spin rotation plane. A phase diagram is also established in terms of frustration, biquadratic interaction and Kitaev interaction. Monte Carlo simulations are performed and diverse complex spin textures are predicted. The present findings demonstrate the importance of Kitaev interaction in stabilizing classical noncollinear magnetic orders, besides its relevance to quantum spin liquids.					csxu@fudan.edu.cn
2	Cosimo Bambi	Testing General Relativity with black hole X-ray data	The theory of General Relativity has successfully passed a large number of observational tests. The theory has been extensively tested in the weak-field regime with experiments in the Solar System and observations of binary pulsars. The past 5-6 years have seen tremendous progress in the study of the strong-field regime, which can now be tested with gravitational waves, X-ray data, and mm Very Long Baseline Interferometry observations. In my talk, I will summarize the state-of-the-art of the tests of General Relativity with black hole X-ray data, discussing its recent progress and future developments.					bambi@fudan.edu.cn
3	顾嘉荫	SMEFT at future lepton colliders	With the completion of the Standard Model, there is no guarantee that new particles can be found at current or future colliders. Meanwhile, precision measurements of the Higgs and electroweak bosons at future lepton colliders offer a great opportunity for probing new physics beyond the Standard Model. The Standard Model Effective Field Theory (SMEFT) provides an ideal framework for a model-independent interpretation of these measurements. In this talk, I will try to provide an overview on the global SMEFT analyses at future lepton colliders, highlight some of my own work, and briefly discuss how these analyses could benefit from machine learning techniques.					jiayin_gu@fudan.edu.cn
4	万义顿	Experimental realization of a topologically protected Hadamard gate via braiding Fibonacci anyons	Topological quantum computation (TQC) is one of the most striking architectures that can realize fault-tolerant quantum computers. In TQC, the logical space and the quantum gates are topologically protected, i.e., robust against local disturbances. The topological protection, however, requires rather complicated lattice models and hard-to-manipulate dynamics; even the simplest system that can realize universal TQC–the Fibonacci anyon system–lacks a physical realization, let alone braiding the non-Abelian anyons. Here, we propose a disk model that can realize the Fibonacci anyon system, and construct the topologically protected logical spaces with the Fibonacci anyons. Via braiding the Fibonacci anyons, we can implement universal quantum gates on the logical space. Our proposal is platform-independent. As a demonstration, we implement a topological Hadamard gate on a logical qubit through a sequence of 15 braiding operations of three Fibonacci anyons with merely 2 nuclear spin qubits. The gate fidelity reaches 97.18% by randomized benchmarking. We further prove by experiment that the logical space and Hadamard gate are topologically protected: local disturbances due to thermal fluctuations result in a global phase only. Our work is a proof of principle of TQC and paves the way towards fault-tolerant quantum computation.					ydwan@fudan.edu.cn
