I received Ph.D degree in solid state physics from TU-Dresden in 1999. Before 2007, I proposed the mean-field and perturbation theory to investigate the roles played by the crystal-field levels and RKKY interactions, and estimated magnetic transition temperatures of rare-earth systems. In 2008, I built a two sub-lattice model to describe antiferromagnetic (AFM) rare-earth compounds, overcoming a difficulty met by experimental physicists.
Since 2010, I have been working on developing two quantum computational methods, namely the self-consistent approach (SCA) and quantum Monte Carlo method (QMC). In these models, the spins in Hamiltonians are quantum operators instead of classical vectors, all physical quantities are evaluated with quantum formulas.
The uncertainty principle of quantum theory makes it possible for the SCA code to tunnel through energy barriers, and quickly converge to the equilibrium states of the systems, without elaborate artificial manipulation.
In 2018, I optimized the QMC method , so that the results obtained in the last iteration can produce well symmetric and periodic spin configurations, e.g., of two-dimensional (2D) AFM skyrmionic crystals, which no body has been able to generate in simulations.
Recently I successfully applied the SCA to simulate the ferroeletric (FE) and antiferroelectric (AFE) skyrmionic crystals in 2D multi-ferroic materials, the topological charges of crystals are found, for the first time in the world, to be quantized.
Moreover, the above two quantum methods have been granted Chinese patent licenses, and they are currently being improved by combining with other theory in order to simulate large magnetic systems, which will be published in a few months.
