GW240925 and GW250207: Astrophysical Calibration of Gravitational-wave Detectors
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1839
GW240925 and GW250207 are two loud gravitational-wave signals from binary black hole coalescences observed with network signal-to-noise ratios and , respectively…
Microscopic Theory of Chiral-Phonon-Induced Orbital Selectivity in Helical Crystals
Tomomi Tateishi, Akihito Kato, Alexander S. Ovchinnikov +1
We present a microscopic theory of chirality-induced orbital selectivity (CIOS) in helical crystals, in which truly chiral phonons selectively transfer angular momentum to electron…
Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853
Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…
Quarkyonic matter and hadron-quark crossover from an ultracold atom perspective
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
The dense matter equation of state is of great interest due to the recent development of astrophysical observations for neutron stars. A rapid increase in pressure indicates a cont…
TopiCLEAR: Adaptive embedding clustering for interpretable topic discovery from short texts
Aoi Fujita, Taichi Yamamoto, Yuri Nakayama +1
Topic discovery is a fundamental technique for text mining that identifies abstract topics within large document collections. A recent approach to topic discovery is to cluster doc…
Possible mixing between elementary and bound state fields in the production excess at the LHC
Yoshiki Matsuoka
Recent report by CMS Collaboration on the excess of top and anti-top pair production is studied, under the hypothesis of the coexistence of a toponium and an additional ele…
