Research Interests

Strongly correlated (model) systems, with quantum Monte Carlo.

Currently applying neural network quantum Monte Carlo (NNQMC, NNVMC, ML-VMC) to studying quantum phases in strong-correlated systems, such as:

• Tomonaga-Luttinger liquid @ ab inito hydrogen chain
• Correlated insulators @ Moire systems.

Previously struggled with Hubbard model using FCIQMC.

Misc.

• “Haoxiang” sounds like “how-shuaang”. “X” sounds more like “ch” in “sprichst” if you know Deutsch.

Non-academic part

• 谜题巡猎 / puzzle hunt:
  • CCBC13&14 (Eat Well Sleep Well); MiaoHunt 2023 (猫猫鉴赏团); CCBC9R (一届好题); P&KU3上 (江南四大才子); CCBC15 (一队好人)
  • 城市定向系列: MV4, MVϑ, MV5
• (休闲) 骑行:
  • “禅与自行车维修艺术”: 车的齿轮如何运转一般还是直观的、讲道理的，可以假设与检验；但是提出假设的过程不是完全理性的，而需要基于”经验”
  • 喜欢蹦蹦跳跳，所以和公路车大抵没什么缘分
• 学习语言:
  • 浅尝辄止，基本上是为了好玩
  • 普通话(流利); 闽南语(能说), English (can speak); 日本語 (学んでいる); Deutsch (nur ein bisschen)
• 写信:
  • 收到明信片时很快乐

About this blog

• About physics, shower thought and randomness.
• Basically written in Chinese, 物理随笔中不想强调的部分会用英文写.
