来自江西省宜春市高安市的美丽乡村：太阳镇西阳村。
I am the son of the Sun！
My surname is Liu, and I’m a Leo, so ‘Leo’ represents both my zodiac sign and is also a phonetic translation of my surname.

💻 RESEARCH EXPERIENCE
- Tensor Network Methods:
- Simulating Quantum States of 1D Lattice Models:
- Tensor Renormalization Group (TRG):
Utilized Matrix Product States (MPS) to simulate quantum states of a 1D lattice model through MATLAB and Python. Applied imaginary time evolution to solve for the ground state energy of the 1D Heisenberg model using the imaginary Time Evolution Block Decimation (iTEBD) algorithm.
Implemented the Trotter-Suzuki decomposition of the imaginary time evolution operator for the 1D Transverse Field Ising Model. Developed a 2D tensor network using Matrix Product Operators (MPOs) and employed Higher Order Tensor Renormalization Group (HOTRG) for efficient contraction.
- Fisher Zeros and Quantum Phase Transitions:
Analyzed Fisher zeros in the 1D-TFIM, revealing distinct smooth curves in the complex beta plane across a quantum critical point. The results refined Suzuki’s solution, providing new analytical predictions about quantum dynamics. Extended this framework to other spin models, opening avenues for studying quantum critical systems in higher dimensions.
