| 研究実績の概要 |
In the past year I have published 5 papers. Three of these papers described the role of quantum speed limits in the control of interacting many-body states. Specifically, my paper in Physical Review Letters was the first to show that the appearance of dynamical orthogonality in many-body states is given exactly by the quantum speed limit time. Two further publications explored correlations in interacting few-body systems.
Currently I have two manuscripts being reviewed, one at Physical Review Letters on non-equilibrium thermometry of Fermi gases, the other at New Journal of Physics on shortcuts to adiabaticity in strongly interacting quantum heat engines.

現在までの達成度 (区分)
1: 当初の計画以上に進展している
理由
At the moment I am preparing two manuscripts: 1) The effect of dynamical criticality of many-body quantum heat engines and 2) out-of-time correlation functions and work statistics of quenches in few-body interacting systems. These works are a continuation of my previous work on the control of interacting systems and quantum speed limits. As the majority of the analytic and numerical calculations have been complete the projects have been completed successfully.

| 今後の研究の推進方策 |
I have currently begun 3 projects which explore different aspects of quantum control and thermodynamics. 1) Machine learning techniques for thermometry of many-body quantum gases, 2) Controllable quantum heat junction between two many-body states, 3) Emergence of quantum chaos in interacting few-body systems. These projects feature collaborations with researchers in OIST (1 and 2) and international collaborators (3).

| 次年度使用額が生じた理由 |
I plan to use this money to attend JPS Spring meeting, few-body physics conference in Germany and for research visit to Valencia, Spain to work on a project which looks at quantum chaos and thermodynamics.
