報(bào)告人簡(jiǎn)介：Dr. Jun Lu joined the National University of Singapore (NUS) in 2025 under the Presidential Young Professor (PYP) scheme. He earned his B.Sc. in Chemistry from Changchun Normal University in 2012 and his Ph.D. in Chemistry from Jilin University in 2018 under the supervision of Prof. Kun Liu. He subsequently conducted postdoctoral research at the University of Michigan with Prof. Nicholas Kotov. At NUS, Dr. Lu established the Topological Engineering of Asymmetrical Nanointerfaces (TEAN) Lab, where his group pioneers the design and control of asymmetric atomic- and nanoscale interfaces to unlock novel quantum optical, thermal, and biological functionalities. He has achieved fruitful achievement in publication on jounals including Science (2) and Nature (2) as first/co-first authors.
報(bào)告簡(jiǎn)介：Chirality is a fascinating phenomenon ubiquitous in nature, governing structures from molecular configurations to biological systems. Over the past decade, chirality has increasingly entered the realm of materials science, enabling breakthroughs in photonics, catalysis, and beyond. In this talk, I will present recent advances in inorganic chirality by exploiting geometric frustration to drive spontaneous twisting into complex chiral architectures. By rationally tuning particle geometry, ligand chemistry, and intrinsic interactions, we can programmably control both the handedness and the interplay of optical anisotropy, leading to robust confinements to the photon spin angular momentum, even with thermal excitation. Extending chirality from the nanoscale down to the atomic level, our current efforts focus on integrating machine learning and advanced manufacturing platforms for precision control of inorganic chiral architectures. These approaches seek to confine multiple spin and orbital information of photon and heat within asymmetric atomic and nanoscale interfaces. We aim to uncover the interlinked dynamics among chiral electrons, photons, and phonons, opening new avenues for engineering quantum optical, thermal, and even biological functionalities.
