报告提纲

• A new generic way to access eigenstates inside the spectrum is proposed within the context of matrix product state (MPSs)

• With the above method, plus excited state level-crossing analysis, we determined the ground state phase diagram of the spin-1/2 J1-J2 Antiferromagnetic (AF) Heisenberg model on square lattice

• Combined with real time evolution using Time Dependent Variational Principle (TDVP) applied to MPSs, we studied the dynamics structure factor for the spin-1/2 AF Heisenberg chain

• Conclusion and remarks

个人简介

Ling Wang, assistant Professor at Beijing Computational Science Research Center. She work in condensed matter theory, specializing in computational simulations of strongly correlated quantum systems. What interests her are the exotic states of matter that can emerge from the strong interactions among the particles, such as electrons or ions, that make up these systems. These include high-temperature superconductors, one dimensional electron arrays, and exotic particles that have promise as elements in quantum computing. These systems have unusual characteristics, and modeling them has been a formidable problem in physics. Her research involves developing simple, workable models that can improve our ability to understand and predict their properties and behavior.

会议简介

This workshop focus on recent advances in the field of quantum many-body computation, including Monte Carlo methods, renormalization group and tensor network methods, machine learning, etc. It aims to provide young researchers and graduate students with introductory and updated research information, promote exchange of ideas and in-depth discussions, and enhance the interactions of researchers working in relevant areas.

Organizer:  Department of Physics, Renmin University of China
