Infrared Spectroradiometry of Sodium Benzoate from 21 to 235 THz
Yoshitaka Okuyama, Youichi Ishikawa, Daishi Fujita
This paper presents an extensive survey of the thermal radiation properties of lithium benzoate. We heated the sample from 313 to 553 K, just below the melting point, while perform…
Aspects of critical O model with boundary and defect
Yoshitaka Okuyama
In this thesis, we explore the critical phenomena in the presence of extended objects, which we call defects, aiming for a better understanding of the properties of non-local objec…
The epsilon expansion of the O model with line defect from conformal field theory
Tatsuma Nishioka, Yoshitaka Okuyama, Soichiro Shimamori
We employ the axiomatic framework of Rychkov and Tan to investigate the critical O vector model with a line defect in dimensions. We assume the fixed point is describe…
Comments on epsilon expansion of the O model with boundary
Tatsuma Nishioka, Yoshitaka Okuyama, Soichiro Shimamori
The O vector model in the presence of a boundary has a non-trivial fixed point in dimensions and exhibits critical behaviors described by boundary conformal field theo…
Method of images in defect conformal field theories
Tatsuma Nishioka, Yoshitaka Okuyama, Soichiro Shimamori
We propose a prescription for describing correlation functions in higher-dimensional defect conformal field theories (DCFTs) by those in ancillary conformal field theories (CFTs) w…
The International Linear Collider: Report to Snowmass 2021
Alexander Aryshev, Ties Behnke, Mikael Berggren +508
The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our…
Replica wormholes and capacity of entanglement
Kohki Kawabata, Tatsuma Nishioka, Yoshitaka Okuyama +1
We consider the capacity of entanglement as a probe of the Hawking radiation in a two-dimensional dilaton gravity coupled with conformal matter of large degrees of freedom. A formu…
Probing Hawking radiation through capacity of entanglement
Kohki Kawabata, Tatsuma Nishioka, Yoshitaka Okuyama +1
We consider the capacity of entanglement in models related with the gravitational phase transitions. The capacity is labeled by the replica parameter which plays a similar role to…
Regge OPE blocks and light-ray operators
Nozomu Kobayashi, Tatsuma Nishioka, Yoshitaka Okuyama
We consider the structure of the operator product expansion (OPE) in conformal field theory by employing the OPE block formalism. The OPE block acted on the vacuum is promoted to a…
