A rational deferred correction approach to parabolic optimal control problems [PDF]
, 2016 The accurate and efficient solution of time-dependent PDE-constrained optimization problems is a challenging task, in large part due to the very high dimension of the matrix systems that need to be solved.

Methodology for Fabrication-Tolerant Planar Directional Couplers
IEEE Photonics Journal, 2022 A new methodology for realizing fabrication-tolerant planar directional couplers is proposed and experimentally demonstrated. Performance of power splitting and WDM couplers can be made highly tolerant to typical process errors when an appropriate center-

Unifying time evolution and optimization with matrix product states [PDF]
, 2015 We show that the time-dependent variational principle provides a unifying framework for time-evolution methods and optimisation methods in the context of matrix product states.

Correlations of stripe phase in one-dimensional spin-orbit coupled Bose gas
Physical Review Research, 2021 We investigate the effects of interaction for the stripe phase of a homogeneous one-dimensional Bose gas with laser-induced Raman spin-orbit coupling (SOC) and Zeeman splitting, for a wide range of densities. In order to account for quantum fluctuations,

Simple SUSY Breaking Mechanism by Coexisting Walls [PDF]
, 2001 A SUSY breaking mechanism with no messenger fields is proposed. We assume that our world is on a domain wall and SUSY is broken only by the coexistence of another wall with some distance from our wall.
