Akinori Tanaka received particle physics medal


Our iTHEMS member, Dr. Akinori Tanaka (AIP/iTHEMS) together with Dr. Akio Tomiya (RIKEN BNL Research Center) have received "14th Particle Physics Medal: Young Scientist Award in Theoretical Particle Physics” from Japan Particle and Nuclear Theory Forum. They were awarded in recognition of their recent paper: Akinori Tanaka, Akio Tomiya “Detection of Phase Transition via Convolutional Neural Networks,” J. Phys. Soc. Jpn. 86, 063001 (2017).
The citation reads: This paper answers the important question of whether machine learning can capture the existence of phase transition. In this study, in the classical Ising model, spin configurations at various temperatures are generated, and pairs of (configuration, temperature) are used as data. A convolutional neural network is prepared, input data is set, output data is temperature, and machine learning is performed to predict the temperature from the configuration. In the obtained neural network, when the weight of the network connecting the final layer and the layer immediately before it is plotted as a heat map, it can be seen that a large change occurs near the phase transition temperature. This is evidence that machine learning has captured a phase transition. This paper, which shows that machine learning can not only reproduce and use known concepts but also extract the physical concept of phase transition point, is very original and links the subsequent physics and machine learning It made one of the foundations of research. From these facts, we consider this paper to be an award-winning paper.

Congratulations, Akinori and Akio!

1-day Workshop on Quantum Gravity

July 4 at 9:30 - 18:00, 2019

In order to construct a quantum theory of gravity, it is currently required to study freely from various viewpoints. In this small workshop, we will discuss various different topics such as field theory, string theory, quantum black hole, quantum universe and so on, and will consider future directions to quantum gravity casually but deeply. Let's enjoy exciting discussions!

Venue: #132, 1F, Main Research Building, RIKEN

Event Official Language: English

Workshop on Sine-square deformation and related topics 2019

July 11 at 10:00 - 18:00, 2019

Sine-Square Deformation (SSD) is a newly found boundary condition that involves the spatial modulation of the coupling constant of quantum systems.
Since its discovery, it has received broad attention in the context of various research field. This workshop aims at offering the opportunities for the researchers interested in SSD to convene and exchange ideas on the subject.

Venue: #435-437, Main Research Building, RIKEN

Interstellar Memes

July 25 at 20:00 - 21:30, 2019

Dr. Don Warren (Research Scientist, iTHEMS)

Memes are to cultures what genes are to people: ideas, behaviors, or styles that are transmitted within the culture and can propagate or die out. The universe is a big place. How much of it knows about Grumpy Cat? Tale of Genji? Earth?
