AbstractThis talk aims to present applications of common mathematical models in permafrost research based on our research experience. (1) Permafrost distribution model (active layer thickness and mean annual ground temperature); (2) Unfrozen water content calculation models; (3) Thermal disturbance of improved cemented frozen soil; (4) Hydro-thermal-salinity coupling model.Speaker IntroMingtang...
Abstract:Entanglement detection is essential in quantum information science and quantum many-body physics. It has been proved that entanglement exists almost surely for a random quantum state, while the realizations of effective entanglement criteria usually consume exponential resources, and efficient criteria often perform poorly without prior knowledge. This fact implies a fundamental limit...
