BCF anomaly and higher-group structure in the low energy effective theories of mesons
Tatsuki Nakajima, Tadakatsu Sakai, Ryo Yokokura
We discuss the BCF anomaly of massless QCD-like theories, first obtained by Anber and Poppitz, from the viewpoint of the low energy effective theories. We assume that the QCD-like…
Fast Event-based Optical Flow Estimation by Triplet Matching
Shintaro Shiba, Yoshimitsu Aoki, Guillermo Gallego
Event cameras are novel bio-inspired sensors that offer advantages over traditional cameras (low latency, high dynamic range, low power, etc.). Optical flow estimation methods that…
Thermodynamic geometry of ideal quantum gases: a general framework and a geometric picture of BEC-enhanced heat engines
Joshua Eglinton, Tuomas Pyharanta, Keiji Saito +1
Thermodynamic geometry provides a physically transparent framework to describe thermodynamic processes in meso- and micro-scale systems that are driven by slow variations of extern…
Non-Hermitian topological Fermi superfluid near the -wave unitary limit
Hiroyuki Tajima, Yuta Sekino, Daisuke Inotani +3
We theoretically discuss the non-Hermitian superfluid phase transition in one-dimensional two-component Fermi gases near the -wave Feshbach resonance accompanied by the two-body…
Symmetries and Synchronization Blockade
Parvinder Solanki, Faraz Mohd Mehdi, Michal Hajdušek +1
Synchronization blockade refers to an interferometric cancellation of quantum synchronization. In this manuscript, we show how the choice of synchronization measure and Hamiltonian…
A Fast Geometric Regularizer to Mitigate Event Collapse in the Contrast Maximization Framework
Shintaro Shiba, Yoshimitsu Aoki, Guillermo Gallego
Event cameras are emerging vision sensors and their advantages are suitable for various applications such as autonomous robots. Contrast maximization (CMax), which provides state-o…
Intertwined Orders and Electronic Structure in Superconducting Vortex Halos
Yi-Hsuan Liu, Wei-Lin Tu, Gia-Wei Chern +1
We present a comprehensive study of vortex structures in -wave superconductors from large-scale renormalized mean-field theory of the square-lattice -- model, which ha…
Interaction in Remote Peddling Using Avatar Robot by People with Disabilities
Takashi Kanetsuna, Kazuaki Takeuchi, Hiroaki Kato +4
Telework "avatar work," in which people with disabilities can engage in physical work such as customer service, is being implemented in society. In order to enable avatar work in a…
Resurgence in 2-dimensional Yang-Mills and a genus altering deformation
Toshiaki Fujimori, Philip Glass
We study resurgence in the context of the partition function of 2-dimensional and Yang-Mills theory on a surface of genus . After discussing the properties of the…
A mathematical analysis of the Kakinuma model for interfacial gravity waves. Part II: Justification as a shallow water approximation
Vincent Duchêne, Tatsuo Iguchi
We consider the Kakinuma model for the motion of interfacial gravity waves. The Kakinuma model is a system of Euler-Lagrange equations for an approximate Lagrangian, which is obtai…
Effect of surfactants on the elasticity of the liquid--liquid interface
Shunta Kikuchi, Hiroshi Watanabe
We investigated the effect of surfactants on an interface between two kinds of liquid by molecular dynamics simulation. We adopted the simple bead-spring model with two atoms as th…
A Right-handed Neutrino Portal to the Hidden sector : Active Neutrinos and their Twins in an F-theory model
Junichiro Kawamura, Stuart Raby
We analyze the neutrino phenomenology in an F-theory model with both a visible sector and a twin hidden sector. At low energies, the strong and weak scales of the two secto…
Path-integrals of perturbative superstrings on curved backgrounds from string geometry theory
Matsuo Sato, Kunihito Uzawa
String geometry theory is one of the candidates of the non-perturbative formulation of string theory. In this paper, from the string geometry theory, we derive path-integrals of pe…
Higher-group structure in -dimensional axion-electrodynamics
Tatsuki Nakajima, Tadakatsu Sakai, Ryo Yokokura
We investigate -dimensional axion electrodynamics for the purpose of exploring a higher-group structure underlying it. This is manifested as a Green-Schwarz transformation of t…
The Effect of Shock Wave Duration on Star Formation and the Initial Condition of Massive Cluster Formation
Daisei Abe, Tsuyoshi Inoue, Rei Enokiya +1
Stars are born in dense molecular filaments irrespective of their mass. Compression of the ISM by shocks cause filament formation in molecular clouds. Observations show that a mass…
Spin hydrodynamic generation in unsteady flows
Takumi Funato, Mamoru Matsuo
We theoretically investigate a spin-mediated conversion from fluid dynamics to voltage, known as spin hydrodynamic generation (SHDG), in oscillatory and transient unsteady flows. W…
Dirac Kondo effect under magnetic catalysis
Koichi Hattori, Daiki Suenaga, Kei Suzuki +1
We develop a mean-field theory of a novel Kondo effect emerging in systems without a Fermi surface, which instead emerges under strong magnetic fields. We determine the magnitude o…
Efficient Dicke state generation in a network of lossy channels
Wojciech Roga, Rikizo Ikuta, Tomoyuki Horikiri +1
We analyze the generation of entanglement in a multipartite optical network. We generalize the twin-field strategy to the multipartie case and show that our protocol has advantageo…
