I am studying PhD in Theoretical Physics under the supervision of Professor Sean Hartnoll in DAMTP, Cambridge, sponsored by the Gates Foundation. I previously studied Part I Engineering, switched to Mathematics and completed Part IB, II and III in Cambridge, mainly focused on Theoretical/High Energy Physics. I am very grateful for the generous support of the Jardine Foundation for my undergraduate study.
Researches
SU(3) lattice gauge theory
I did a project with Dr Bipasha Chakraborty on SU(3) Lattice Gauge Theory during summer 2021. In this project, I tried to develop a locally gauge-invariant formulation for the Kogut-Susskind Hamiltonian, which solves the non-abelian Gauss Laws. Based on this formulation, it is possible to develop effective quantum algorithms to calculate this system in the strong-coupling regime. I did a presentation and the up-to-date report can be found here.
Mathematical biology
During 2020 Summer, I worked under the supervision of Professor Raymond Goldstein in the area of Mathematics Biology in Cambridge. The research was to explain why p. lunula, a marine microorganism, adopts a non-axisymmetric shape resembling a crescent moon. I proposed that the strange shape may have some optical properties that help its photosynthesis process. Here’s a presentation and a report of my research. I am now collaborating with Dr Sumit Birwa on validating the results.
Quantum information
In 2019, I was supervised by Professor Giulio Chiribella and Dr Ravishankar Ramanathan in HKU on the topic of quantum information theory. I proved a no-side-channel theorem for a time-reversal scheme, which guarantees that the time-reversal map can be viewed as a free source. A paper finally came out 5 years after my project started. I also worked on dense coding where several classical bits are encoded into a qubit and decoded probabilistically. I found and proved a tight bound of a communication protocol similar to 2-bit dense coding using the geometric method.
Maths Blogs
Here is a list of courses I took in PartIB, PartII and Part III Mathematics Tripos.
I did an essay for my Part III on the C-theorems.
Here are the related notes for areas that I am/was interested, mostly concentrating on aspects of theoretical physics.
Projects
In 2017, I was admitted to a joint scheme between Hong Kong University and University of Cambridge, studying Engineering. In 2018, I went to Cambridge, studied Engineering Tripos for a year before switching to Mathematics. The two years of Engineering training brought me unique viewpoints on problems and made me competent in programming languages. I found these very useful in later study and research.
Here is a list of what I have done.
Others
I am an amateur photographer. I have a Chinon CM-5 film camera and enjoy old-school photo development and printing techniques. I also have a Sony DSLR camera so that I’m not too far behind the technologies. Here’s my photo collection.
I’m recently into Drone Videography. CAA A2 certificate holder. Qualified pilot operating in the UK, Europe and the US. I usually upload things on my Youtube Channel. Also, I proudly participated in making the advertisement of KIT Physics.
I am on my way to becoming a solo glider pilot.
I love kayak and Paddleboarding. I am also a ski lover, a traveller and a guitarist. On June 18, 2022, we played the Undertale BGM at the Frazer room, Trinity College Cambridge.
I helped out with the Gates Scholarship Orientation 2023 at the Peak District. Following my fellow scholar friend’s wonderful idea, I hosted a creative writing workshop on collective storytelling. First we had the exquisite corpse drawing game to warm up, then the Six Word Fiction, and finally each group wrote collaboratively without communicating. It went gorgeous. Everyone is a creative writer by nature.
I participated in a Sci-fi Chain-writing event arranged by CUSFS. You can find the electronic version here.
And I’m a big movie fan.
