• Computational physics
• First-principle methods of electronic structure theory.
• Application of such methods to study properties of solids, surfaces and clusters.
• Computational material science
• Design of materials with features desired.
• Materials used to store or generate energy.

This project is supported by Hui-Chun Chin and Tsung-Dao Lee Chinese Undergraduate Research Endowment (CURE) in FDUROP.

I implemented an algorithm(C & Fortran hybrid) to design materials with desired feature values. In this project, I debugged and tested the code on binary alloys. Then, I added functional modules to calculate semiconductors` properties and obtained novel four-element alloys. Besides, my program was able to design materials with arbitrary supercell and thus find structures left out by traditional method which combines simulated annealing with superlattice. Up till now, I have written almost 2500 lines of codes originally.

My application proposal in Chinese is here. Code is not available currently.

I wrote Ccodes based on my reading of Simulated Annealing and added Conjugated Gradient local optimizer which improved the precision in three orders of magnitude. Then, I used them to find the most stable distributions of electrons residing on a unit sphere shell. I visualized structures I found, studied the symmetries of distributions and verified Altschuler Conjecture to the extend of hundreds of electrons. ==== Presentation Report & Codes ==== {{:home:students:luoye:推广的模拟退火算法解决电子在球面上的分布.pdf Report}}presentationCode Package in C++ ==== Simulated Annealing + Thomson Model ==== ===== Investigation on Chua's Nonlinear Circuit ===== See details in Chinese
I did a systematical experimental research on Chua`s nonlinear circuit. With circuit parameters obtained, the simulation I did generated phase diagrams and a bifurcation figure in conformity with experiments. Moreover, I theoretically proposed several methods to improve the old apparatus and selected the best one by simulation. The new design facilitated demonstration of chaotic mechanism in Chua`s circuit. ==== Presentation Report & Codes ==== Report Presentation PartA Presentation PartB

===== Automatic Meeting Calculagraph ===== I offered the idea and designed an archetype. I wrote codes for both single-chip-microcomputer and computer interface. After testing the product in a large number of occasions, I made the final version and wrote applications for a patent(China Patent No. 200910055820.X.). ===== Evaluation of Commercial Batteries ===== I designed a circuit to measure capacities of 8 types of batteries sold in the market via data acquisition card LabJack. I also made a report about their cost performances.
