Local expression of fractional corner charges in obstructed atomic insulators and relationship with the fractional disclination charges
Hidetoshi Wada, Shuichi Murakami
In obstructed atomic insulators, fractionally quantized charges appear at the corners of the crystals in the shapes of vertex-transitive polyhedra, and are given by the filling ano…
Generalized Nagaoka ferromagnetism accompanied by flavor-selective Mott states in an SU() Fermi-Hubbard model
Juntaro Fujii, Kazuki Yamamoto, Akihisa Koga
We study the ferromagnetic instability in an SU() Fermi-Hubbard model on the hypercubic lattice. Combining dynamical mean-field theory with continuous-time quantum Monte Carlo s…
Emotion Recognition in Multi-Speaker Conversations through Speaker Identification, Knowledge Distillation, and Hierarchical Fusion
Xiao Li, Kotaro Funakoshi, Manabu Okumura
Emotion recognition in multi-speaker conversations faces significant challenges due to speaker ambiguity and severe class imbalance. We propose a novel framework that addresses the…
Search for planetary-mass ultra-compact binaries using data from the first part of the LIGO--Virgo--KAGRA fourth observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
We present a search for gravitational waves from inspiraling, planetary-mass ultra-compact binaries using data from the first part of the fourth observing run of LIGO, Virgo and KA…
Critical Berezinskii-Kosterlitz-Thouless dynamics in the archetypal two-dimensional spin system BaCuSiOCl
K. M. Ranjith, Maxime Dupont, Steffen Krämer +6
We study the spin dynamics in the quasi-2D spin- dimer compound BaCuSiOCl, which exhibits a magnetic field-induced Bose-Einstein condensate (BEC) of triplons.…
Electron Recoil via Sample Momentum Transfer under Optical-Mode Excitation
Akira Yasuhara, Yamato Kirii, Takumi Sannomiya
The interaction between free electrons and optical modes underlies a variety of quantum and nanoscale light-matter phenomena, yet the associated momentum exchange with the sample l…
