Speaker: Prof. HUANG Qihai (University of Huddersfield)Host: Prof. HU Qiongjing (Zhejiang University)Venue: Room 723, Building A, School of Management, Zijingang CampusAbstract: Online labor platforms (OLPs) employ algorithmic management practices to manage app-workers. Drawing upon the self-determination theory, this research examines the impact of perceived algorithmic management practices (PAMP) on the service performance of ride-hailing drivers through three studies. We theorise the process by investigating the mediating roles of individual needs satisfaction (competence, autonomy, and relatedness) and work engagement, and the moderating role of online community support (OCS). We developed and validated a PAMP scale using a rigorous multistep process in the first study. In the second study, we empirically tested our conceptual model with a sample of 431 ride-hailing drivers. Our findings reveal that PAMP influences drivers’ competence, autonomy, and relatedness needs satisfaction differently. The satisfaction of these three basic needs enhances work engagement, subsequently improving service performance.Furthermore, OCS positively moderates the relationship between PAMP and drivers’ needs satisfaction. To deepen our understanding of how PAMP influences drivers’ needs satisfaction and subsequent behaviors, we conducted a qualitative investigation with 103 ride-hailing drivers. Our study provides valuable insights for future research and practice in managing app-workers in the gig economy.

Speaker: Prof. CHEN Yanze (University of Alberta)Venue: Room 101, Building 2, Haina Court, Zijingang CampusAbstract: An analogue of the Segal-Shale-Weil representation for loop symplectic groups over a local field was constructed by Zhu 15 years ago. For a reductive dual pair in a symplectic group over a global field, one can thus consider the analogue of the global theta lifting of an automorphic form in the context of loop groups. We computed the theta liftings of a "cusp form" on the loop GL(n) group induced from a "classical" cusp form for the loop group dual pair (GL(n),GL(n)), and explained the result an Eisenstein series. In this computation, an interesting model of the local loop Weil representation is introduced, which is essentially due to Kapranov. This is a joint work with Yongchang Zhu.Contact person: Prof. LIU Dongwen (maliu@zju.edu.cn）

Speaker: Prof. Zhimin ShiVenue: Online (Zoom ID: 851 7706 1692)Abstract:The first part of the talk is centered around understanding and utilizing high-dimensional light, also known as structured light. I will first present a family of direct tomography protocols that can characterize various types of structured light or high-dimensional photon states. I will introduce some high-performance mode sorters for structured light as well as a series of scan-free direct tomography protocols that can measure high-dimensional spatial modes, spatial vector modes and partially-coherent modes (mixed states). The direct tomography methods directly relate the readouts to the complex-valued description of the photon states to be measured, and can measure the entire photon state in a single experimental setup without any need of scanning. Consequently, direct measurements become critical in enabling real-time metrology of both quantum and classical photon states. I will will present some recent work on robust high-information-capacity optical communication protocols in turbulent environment, including a turbulence-resilient vector beam based communication protocol, a phase conjugation based scheme to enable communication using OAM modes with low crosstalk through a 340m free-space-link, and a vector phase conjugation scheme that can enable 210-spatial-polarization mode communication through 1 km of multi-mode fiber. These breakthroughs can lead to practical carryout of high-dimensional optical communications in realistic environment. The second part of the talk is to introduce Meta’s vision and efforts to empower people to connect with each other and the world around them. In specific, I will present some collective work from Reality Labs – Research to address one question: “What will we need for future VR’s display?”Profile of the speaker: Zhimin Shi received his Ph.D. degree in Optics from the University of Rochester in 2011.

Speaker: Prof. LU JiongVenue: Online (Zoom ID: 882 1089 8817)Abstract: Atomic-precision manufacturing of artificial quantum states of matter with high digital fidelity and desired quantum states not only presents exciting opportunities for exploring fundamental quantum physics, but also marks a crucial step towards the realization of atomic-scale devices for future quantum technologies. The current strategy of creating these quantum architectures mainly relies on atom-by-atom, molecule-by-molecule manipulation, or molecular assembly through non-covalent interactions, which may lack sufficient chemical robustness required for on-chip quantum device operation at elevated temperature. In this talk, I will discuss the bottom-up fabrication of robust organic quantum corrals, as well as periodic quantum corrals (eg. molecular superlattices) with flat bands. I will also present atomically precise vacancy-assembled quantum antidots in a 2D transition metal dichalcogenide. The resulting antidots have tunable quantum hole states, which are robust to oxygen substitutional doping, and could have applications in quantum information technologies. Profile of the speaker: Prof. LU Jiong holds Dean’s Chair Professorship, associate professor at Department of Chemistry and Institute for Functional Intelligent Materials at NUS.

Speaker: Prof. Nigel HusseyVenue: Online (Zoom ID: 885 1517 9800)Abstract:In typical metals, the electrical resistivity ρ tends to vanish at the extreme f temperature T and magnetic field strength H, albeit for different reasons. At intermediate temperatures, however, ρ(T) is invariably linear due to the scattering of electrons off phonons – the quantized vibrations of the lattice. Electronphonon coupling is also responsible for superconductivity in many of these metals. Indeed, a robust correlation exists between the coefficient of the T-linear resistivity α and the superconducting transition temperature Tc; a link enshrined in the old adage “bad metals make good superconductors”. Despite being discovered almost four decades ago, the high-Tc cuprates still boast the highest ambientpressure Tc values of all known materials. Intriguingly, a similar correlation between α and Tc exists in cuprates too, prompting many in the field to argue that whatever is the cause of this (T-linear) scattering is also the pairing mechanism for high-temperature superconductivity. Despite a prolonged and intense search, however, the origin of this scattering has not been identified. Crucially, the linearity in ρ in cuprates extends over an anomalously broad temperature and field range, implying an unconventional electronic state. Moreover, the H-linear resistivity has a slope ϒ that also correlates with Tc. In this colloquium, I will discuss the profound implications of these correlations, along with a number of other simple observations linking the (magneto)transport properties of cuprates with their corresponding superconducting properties. Collectively, these observations motivate the search for an entirely new paradigm for hightemperature superconductivity, one in which these T- and H-linearities play a central role.Profile of the speaker:Nigel Hussey has been full professor since 2006, initially at the University of Bristol then from 2013 at Radboud University. From 2013 until 2018, he also served as director of the High Field Magnet Laboratory. His research focuses on precision measurements of the transport properties of exotic, low-dimensional metals and superconductors in high magnetic fields. He is credited with the first experimental determination of the full Fermi surface of a high temperature superconductor, and the discovery of the strange metallic state. In recognition of these discoveries, he has been a recipient of the Charles Vernon Boys medal (now the Henry Moseley medal) from the Institute of Physics, the inaugural Brian Pippard superconductivity prize and a Royal Society Wolfson Research Merit award. He is also an elected Fellow of the Institute of Physics. In 2019, Hussey received an ERC Advanced grant.
