Spatiotemporal visualization of a surface acoustic wave coupled to magnons across a submillimeter-long sample by pulsed laser interferometry
Kazuki Maezawa, Shun Fujii, Kazuto Yamanoi +2
Surface acoustic waves (SAWs) coupled to magnons have attracted much attention because they allow for the long-range transport of magnetic information which cannot be achieved by m…
Phase diagram of QCD matter with magnetic field: domain-wall Skyrmion chain in chiral soliton lattice
Minoru Eto, Kentaro Nishimura, Muneto Nitta
QCD matter in strong magnetic field exhibits a rich phase structure. In the presence of an external magnetic field, the chiral Lagrangian for two flavors is accompanied by the Wess…
Scrappy: SeCure Rate Assuring Protocol with PrivacY
Kosei Akama, Yoshimichi Nakatsuka, Masaaki Sato +1
Preventing abusive activities caused by adversaries accessing online services at a rate exceeding that expected by websites has become an ever-increasing problem. CAPTCHAs and SMS…
Workflow for practical quantum chemical calculations with quantum phase estimation algorithm: electronic ground and π-π* excited states of benzene and its derivatives†
Yusuke Ino, Misaki Yonekawa, Hideto Yuzawa +2
Quantum computers are expected to perform the full-configuration interaction calculations with less computational resources compared to classical ones, thanks to the use of the qua…
Convergence of Ginzburg-Landau expansions: superconductivity in the Bardeen-Cooper-Schrieffer theory and chiral symmetry breaking in the Nambu-Jona-Lasinio model
William Gyory, Naoki Yamamoto
We study the convergence of the Ginzburg-Landau (GL) expansion in the context of the Bardeen-Cooper-Schrieffer (BCS) theory for superconductivity and the Nambu-Jona-Lasinio (NJL) m…
Hofstadter-Toda spectral duality and quantum groups
Pasquale Marra, Valerio Proietti, Xiaobing Sheng
The Hofstadter model allows to describe and understand several phenomena in condensed matter such as the quantum Hall effect, Anderson localization, charge pumping, and flat-bands…
Solar neutrino measurements using the full data period of Super-Kamiokande-IV
Kamiokande Collaboration, K. Abe, C. Bronner +322
An analysis of solar neutrino data from the fourth phase of Super-Kamiokande~(SK-IV) from October 2008 to May 2018 is performed and the results are presented. The observation time…
New Classes of the Greedy-Applicable Arm Feature Distributions in the Sparse Linear Bandit Problem
Koji Ichikawa, Shinji Ito, Daisuke Hatano +4
We consider the sparse contextual bandit problem where arm feature affects reward through the inner product of sparse parameters. Recent studies have developed sparsity-agnostic al…
Quantum-centric Supercomputing for Materials Science: A Perspective on Challenges and Future Directions
