摘要:

We demonstrate that hot superheavy nuclei do not retain spherical shapes, as traditionally assumed, but instead equilibrate in deformed—often oblate or triaxial—configurations at finite excitation energy. This behavior arises from a mechanism analogous to the Jahn--Teller effect: spherical systems exhibit high single-particle degeneracy near the Fermi surface, causing their shell corrections to damp out significantly faster with temperature than those of deformed shapes. Using a finite-temperature framework, we reveal a thermally induced inversion of the potential-energy landscape in the Z=118-120 region, where deformed minima become energetically favored at U ≈ 30-50 MeV. This shape inversion fundamentally alters the competition between neutron evaporation and fission. We derive a deformation-dependent correction to the survival probability, revealing a systematic bias in estimates based on spherical ground-state properties.

Our results identify a finite-temperature structure effect that calls for a revision of current models of superheavy nucleus synthesis and decay.

摘要:

In this talk, I will introduce a framework utilizing zero-dimensional defects to analyze light-light-heavy-heavy (LLHH) correlators in conformal field theories. I will apply this formalism specifically to giant graviton correlators in N=4 super Yang-Mills. By combining this defect perspective with analytic bootstrap techniques, I will show how we can completely determine infinitely many four-point correlators at strong coupling. Furthermore, I will highlight a partially broken, higher-dimensional hidden symmetry that packages these correlators into a single generating function which also persists at weak coupling. I will also explain how a systematic operator product expansion analysis allows us to extract nontrivial dynamical information, including the complete spectrum of anomalous dimensions for double-particle operators. Finally, I will demonstrate that this zero-dimensional defect formalism extends far beyond supersymmetry, providing a naturally nonperturbative description for LLHH correlators in any general CFT by reducing four-point conformal blocks to defect two-point blocks in the heavy limit.

摘要:

與自身鏡像無法通過平動和轉動重合的分子被稱為手性分子。手性分子和它的鏡像互為手性異構體。雖然手性異構體有許多相同的物理性質，但是它們卻具有完全不同的化學性質和藥理功能。因此手性分子的研究在醫藥方面具有非常重要的意義。從本世紀初，人們開始研究基于電偶極相互作用形成的循環三能級手性分子模型。在這樣的模型中，左右手性分子將有依賴于手性的不同量子性質，從而可以采用量子力學的方法來進行手性分子的分離、檢測和轉化。本報告將介紹該領域的理論與實驗進展，以及匯報我們在這方面的主要研究工作。

摘要：

Quantum simulation in High Energy Physics (HEP) has advanced significantly in recent years. Nevertheless, further development of a comprehensive simulation framework remains an important challenge. In this talk, I will first highlight the essential role of quantum computing in HEP and review recent progress in the field. I will then discuss the impact of gauge redundancies on quantum simulations of quantum field theories, with particular emphasis on digitization—the encoding of field variables into qubits. Finally, I will present quantum algorithms for the efficient preparation of initial states in quantum field theory simulations.

摘要：

Core-collapse supernovae (CCSNe) are spectacular explosions of dying massive stars and play significant roles in various astrophysical processes. It is a key topic, and still a major difficulty, to determine the progenitors of different types of CCSNe. in this talk, l will describe the general understanding on this topic from past studies and introduce our recent work in this field on a wide range of CCSN types using a combination of different techniques. Our main finding is that interacting binaries play ubiquitous roles in almost all types of CCSNe, from the H-rich Type ll-P to the H-poor Types llb/lb/lc as well as those types with strong interaction with circumstellar material. Future large-scale surveys with high spatial and temporal resolutions (such as Euclid, CSST, LSST and GOTTA) will better reveal the progenitors of CCSNe in the golden era of time-domain astronomy.

摘要:

自由調控電磁波在基礎理論和實際應用(信息、能源、國防）兩方面均有重大意義。然而自然材料對電磁波的調控能力十分有限。過去二十余年間，利用亞波長人工微結構構建的超構材料原則上可具有任意的介電常數和磁導率，實現了遠超自然材料的卓越電磁調控能力。其中，最具突破性的進展之一是超構表面的出現——這種由人工微結構按照特定方式排列而成的平面型超構材料，徹底改變了光場調控的范式。與超構材料不同，超構表面利用電磁波在人工微結構上透/反射時的“界面相位”調控電磁波，因而具有超薄、易制備、高集成、低損耗等突出優勢，一經提出即成為納米光學的研究前沿。本報告將系統回顧從“界面相位”的提出到“平面光學”領域的建立過程，并對該領域的未來發展方向進行展望。
