Optimal Control to Minimize Dissipation and Fluctuations in Open Quantum Systems Beyond Slow and Rapid Regimes
Yuki Kurokawa, Yoshihiko Hasegawa
Optimal control is a central problem in quantum thermodynamics. When minimizing dissipated work and work fluctuations defined via the two-point measurement scheme in open quantum s…
Quantum Reservoir Computing Using Bose-Einstein Condensate with Damping
Yuki Kurokawa, Junichi Takahashi, Yoshiya Yamanaka
Quantum reservoir computing is a type of machine learning in which the high-dimensional Hilbert space of quantum systems contributes to performance. In this study, we employ the Bo…
The lifespan estimates of radially symmetric solutions to systems of nonlinear wave equations in even space dimensions
Yuki Kurokawa
The optimal lifespan estimates of a solution to weakly coupled systems of wave equations have been investigated by many works, except for the lower bound in even space dimensions.…
The blow-up and lifespan of solutions to systems of semilinear wave equation with critical exponents in high dimensions
Yuki Kurokawa, Hiroyuki Takamura, Kyouhei Wakasa
In this paper we prove the blow-up theorem in the critical case for weakly coupled systems of semilinear wave equations in high dimensions. The upper bound of the lifespan of the s…
Weighted HLS inequalities for radial functions and Strichartz estimates for wave and Schroedinger equations
Kunio Hidano, Yuki Kurokawa
This paper is concerned with derivation of the global or local in time Strichartz estimates for radially symmetric solutions of the free wave equation from some Morawetz-type estim…
