报告摘要: We establish optimal error bounds for time-splitting methods and exponential wave integrators applied to the nonlinear Schrödinger equation (NLSE) with low regularity potential and nonlinearity. In many physical applications, low regularity potential and/or nonlinearity are incorporated into the NLSE, such as square-well potential frequently employed in physics literature, disorder potential examined in the context of Anderson localization, and non-integer power nonlinearity in the Lee-Huang-Yang correction used for modelling and simulating quantum droplets.
