Physical Review Research

Quantum physicists have found that the outcomes of measurements are shaped by the complex dynamics of measurement interactions, questioning our usual understanding of observable reality.

Precise control of quantum systems, such as quantum computers, is of great importance for modern quantum science. One way this has been done is via spin echoes. A research group has discovered a new type of echo, labelling them “energy-band echoes.”

Scientists from The University of Tokyo formulated nonlinear, nonequilibrium energy dissipation relationships using methods from geometry to better understand the kinetics of irreversible chemical processes

Researchers at The University of Tokyo create a geometric representation of thermodynamic systems and apply it to self-replicating processes, which may help improve our understanding of the physical constraints of living organisms

Researchers at The University of Tokyo demonstrate the theoretically optimal search method for organisms that employ the “run-and-tumble” technique, and find that it conforms with observations of chemotaxis by E. coli, which may help automate drones

A new study provides a theoretical basis for the influence of learning from ancestors on the acceleration of natural selection using Fisher’s fundamental theorem

Researchers from The University of Tokyo Institute of Industrial Science use optical microscopy to form a picture of what’s really going on inside surfactant onions

Researchers at The University of Tokyo Institute of Industrial Science use artificial intelligence to predict the size of cells over time without the need for simplifying assumptions, which may lead to a new understanding of microbiology principles and improved drug manufacturing from recombinant bacteria

Researchers at The University of Tokyo use the mathematics of adaptive learning and artificial intelligence to describe how T helper cells adjust the response of the vertebrate immune system, which may lead to new vaccines and treatments for infections

Holger F. Hofmann, professor in the Graduate School of Advanced Science and Engineering, Hiroshima University, published a method to experimentally demonstrate the precision of quantum measurements on Feb. 3 in Physical Review Research. His work has implications for our fundamental understanding of physics at the level of individual quantum objects.
