| Achievement |
Theoretical Studies on Cosmological First-order Phase Transitions |
|---|
| Citation |
Dr. Ryusuke Jinno has achieved important results in the theoretical study of gravitational-wave production associated with first-order phase transitions in the early Universe. He extended analytic methods for evaluating gravitational-wave production rates and established a formalism that incorporates the effects of particle production on the friction acting on domain walls. The methods to evaluate gravitational waves that he developed have been adopted in the analyses of observational projects and are highly regarded. He has also proposed new numerical techniques to handle the degrees of freedom of the Higgs field, enabling large-scale simulations. Furthermore, he has conducted a wide range of research in areas including neutrino physics, solitons, leptogenesis, Higgs cosmology, and applications of machine learning, thereby making significant contributions to our understanding of the early Universe from both theoretical and phenomenological perspectives. These remarkable achievements have the potential to lead to observational verification, and thus he is fully deserving of the award.

| Achievement |
Elucidation of Complex Physical Mechanisms Hidden in Everyday Soft Matter Phenomena |
|---|
| Citation |
Dr. Marie Tani drives research to uncover universal physical laws hidden within macro-scale soft matter phenomena, using experiments, theory, and numerical simulations. Her most notable achievement is the study of flexible filaments wrapping around a rotating cylinder. She identified three stable configurations and precisely determined the conditions for their realization, governed by the complex balance of elasticity, gravity, and geometry. This highly original work deeply explores the physics concealed within everyday motions. Dr. Tani also provided crucial insights by expanding soft matter physics to new subjects. This includes establishing the design principle for creating specific three-dimensional shapes from flat Kirigami sheets and elucidating the patterns and mechanisms of scraping of foam on a substrate. Dr. Tani exhibits exceptional insight in identifying physically interesting, multi-factor research subjects (involving elasticity, fluid dynamics, friction, etc.) within daily phenomena and has significantly deepened the fundamental understanding of these fields. Her work is considered worthy of the AAPPS-JPS Award. |

Development of Foundational Technologies toward Realizing Large-Scale Fault-Tolerant Semiconductor Quantum Computers |
|---|
| Citation |
Dr. Akito Noiri has made important contributions to the development of semiconductor-based quantum computers using single electron spins confined in quantum dots as qubits. He has achieved three breakthroughs that have long been regarded as major challenges in this field. First, he realized high-fidelity qubit operations exceeding 99%, satisfying the requirement for fault-tolerant quantum computation. Second, he demonstrated, for the first time in semiconductor qubits, quantum error correction by constructing a logical qubit from three entangled qubits. Third, he established a novel long-distance two-qubit coupling technique that opens the path toward large-scale integration. These achievements were highly cited by the related community. The research made a significant impact on academia in quantum information and related fields. Dr. Noiri's pioneering research places him at the forefront of quantum information science and makes him highly deserving of the AAPPS-JPS Award. |

| Achievement |
Instrumental, Observational, and Theoretical Study on Black Hole Outflow |
|---|
| Citation |
Dr. Misaki Mizumoto is an outstanding early-career astrophysicist whose work has significantly advanced X-ray studies of winds from supermassive black-hole accretion disks. He developed influential theoretical models that successfully reproduce observed spectra of warm absorbers and ultrafast outflows, now widely used in interpreting X-ray data. As a leading member of the XRISM mission, he contributed to major discoveries, including the clumpy structure of SMBH winds and the contrasting behavior of winds from SMBHs and neutron stars. In addition, he has advanced microcalorimeter detector technology by quantifying performance variations under changing observational conditions. His remarkable academic achievements exhibit his talent, and he is expected to be one of the rising leaders in high-energy astrophysics based on his broad expertise in theory, observation, and instrumentation. Dr. Mizumoto's work makes him highly deserving of the AAPPS-JPS Award. |
