Brief About Me

I am driven by curiosity and have studied across various disciplines, including mechanical engineering, physics, and materials science. After graduating from high school, my interest in mechanics and aerodynamics led me to study Power Mechanical Engineering at NTHU. My fascination with mechanics culminated in the invention of patents for a continuously variable transmission, while my enthusiasm for aerodynamics resulted in a published article at the A.A.S.R.C. 2014 conference on the topic of tandem wing design.

During this period, I gradually developed an interest in physics, particularly in superconducting materials. This passion led me to study for a Ph.D. in Materials Science and Engineering, where I began exploring ways to enhance superconductivity from both theoretical and materials research perspectives. Applying my knowledge from mechanical engineering, I constructed automated measurement and powder mixing robotics, accelerating the research process.

Furthermore, I maintained my enthusiasm for fundamental physics by taking courses in General Relativity, Quantum Field Theory, and Statistical Mechanics, and I served as a teaching assistant in the Physics Department, where I was awarded the Outstanding TA Award. My diverse background and expertise allow me to provide innovative solutions to complex problems.

After Ph.D. period, I became a postdoc in Materials Science and Engineering, researching 2D superconducting quantum materials. In the future, I hope to seek employment in the fields of quantum and materials science, aiming to apply cutting-edge technology to practical applications.

Study and Research in Superconducting Qubit

Recently, I established a small education and research group, 𝒊𝑁𝑆𝐼𝐺𝐻𝑇 𝒊ℏ, dedicated to advancing knowledge in superconducting (SC) qubit physics. My work involves studying the Hamiltonian of SC control circuits and employing Python to simulate and visualize qubit state evolution on the Bloch sphere. Our current research focuses on the mathematical frameworks of Lie groups and gauge theory, with an emphasis on their applications in qubit control and topological physics.

▲Simulation of ideal and detuned \(\frac{\pi}{2}-\frac{\pi}{2}\) controls, i.e., the Ramsey experiment.

▲Simulation of detuned \(\frac{\pi}{2}-\frac{\pi}{2}\) control with varying time delays in the Ramsey experiment.

Study and Research in High Entropy Superconductivity

Additionally, we explored the high-entropy counterparts of \(YBCO\) and discovered that these high-entropy counterparts exhibit greater tolerance to doping.

▲The high-entropy counterparts of \(YBCO\) and discovered that these high-entropy counterparts exhibit greater tolerance to doping, as confirmed by XRD analysis of their structural changes.

Progress in Postdoc Works

I have been focusing on the study of 2D quantum materials, specifically 2D Transition Metal Dichalcogenides (TMDs), including \(TaS_2\), \(NbS_2\), and \(VS_2\). These Van der Waals layered materials exhibit promising properties such as superconductivity, charge density waves, and Moiré phenomena.

During my Ph.D., I studied superconducting bulk materials, and now I am gaining more experience in the physics of few-layer materials. TMDs provide an excellent platform for this research, and I am also advancing my skills in scanning tunneling microscopy (STM). Recently, I have been using STM to explore CVD-grown \(TaS_2\) with spiral structures.

This is the powerful of CVD growth method that can fine-tune the chemical composition and provide a fruitful platform for physical researches! (Click to enlarge)

Brief of My Ph.D. Works

My doctoral research focused on how to enhance superconductivity at ambient pressure through materials design. Observing the critical temperature of superconductors, one finds that it increases with the diversity of compound compositions. Extrapolating from this trend, it is anticipated that oxides containing 12 or more elements could achieve room-temperature superconductivity. If we select 12 elements from a commonly used set of 80 elements, there would be at least \(C_{12}^{80}≅10^{14}\) possible combinations! I increased research efficiency from 3 aspects:

1. Propose the theory of critical coupling constants, using this theory to design chemical formulas.\(\to\)Theory of Critical Coupling Constants
2. Automate the preparation of oxide powder compositions to enhance efficiency.\(\to\)Laboratory Automation II: EA-2 Scamander
3. Automate the resistivity temperature 𝝆-T measurements, witch can simultaneously measure multiple samples.\(\to\)Laboratory Automation I: EA-1 Veronica

Teaching Assistant in Physics

I have a minor degree in physics and have taken courses in theoretical mechanics, electromagnetism, and quantum physics. I am particularly interested in the variational principle of least action and Noether’s theorem, which reveal the relationship between symmetry and conservation laws. As a teaching assistant in several physics courses, I received the NTHU Outstanding Teaching Assistant Award in 2019 for my dedicated efforts.

I studied two projects in my bachelor degree:
1. The invention patents of the self-adaptable, positive motion continuously variable transmission (CVT).\(\to\)CVT Patents
2. The second project was the study on the aerodynamic of variable tandem wing aircraft.\(\to\)Tandem Wing Aircraft

The Ability to Learn and Apply Knowledge Across Fields

During my 12 years at National Tsing Hua University, I studied across various disciplines, including mechanical engineering, physics, materials science, and mathematics. I maintained curiosity and strong learning capabilities, integrating knowledge from multiple fields to advance the formulation of superconducting theories, and to automate measurement and powder mixing processes.
