Motion of a superfluid vortex according to holographic quantum dissipation
Wei-Can Yang, Chuan-Yin Xia, Hua-Bi Zeng +2
Vortices are topological defects associated with superfluids and superconductors, which, when mobile, dissipate energy destroying the dissipation-less nature of the superfluid. The…
Cosmic-ray Boron Flux Measured from 8.4 GeV to 3.8 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
We present the measurement of the energy dependence of the boron flux in cosmic rays and its ratio to the carbon flux \textcolor{black}{in an energy interval from 8.4 GeV to 3.…

The East Asian VLBI Network (EAVN) is an international VLBI facility in East Asia and is operated under mutual collaboration between East Asian countries, as well as part of Southe…
A-D hypersurface of supersymmetric gauge theory with flavors
Hiroshi Itoyama, Takeshi Oota, Reiji Yoshioka
In the previous letter, arXiv:2210.16738[hep-th], we found a set of flavor mass relations as constraints that the -deformed quiver matrix model restores the maximal sy…
Chirality-selected crystal growth and spin polarization over centimeters of transition metal disilicide crystals
Yusuke Kousaka, Taisei Sayo, Satoshi Iwasaki +4
We performed a chirality-controlled crystal growth of transition metal disilicide NbSi and TaSi by using a laser-diode-heated floating zone (LDFZ) method. The crystal c…
Radiative gravastar with thermal spectrum; Sudden vacuum condensation without gravitational collapse
Ken-ichi Nakao, Kazumasa Okabayashi, Tomohiro Harada
The gravastar is an exotic compact object proposed as a final product of gravitational collapse of a massive object in order to resolve problems associated with black holes. It is…
Higgs Portal Majorana Fermionic Dark Matter with the Freeze-in Mechanism
Junpei Ikemoto, Naoyuki Haba, Shimizu Yasuhiro +1
We consider a minimal model of fermionic dark matter, in which the Majorana fermion dark matter (DM) couples with the Standard Model (SM) Higgs field through a higher-dimen…
Interpolation and Exponentially Suppressed Cosmological Constant in Non-Supersymmetric Heterotic Strings with General Twists
Yuichi Koga
We study general non-supersymmetric heterotic string models, including so-called interpolating models, -dimensionally compactified with the arbitrary number of freely acting $\m…
Spontaneous symmetry breaking in non-steady modes of open quantum many-body systems
Taiki Haga
In a quantum many-body system coupled to the environment, its steady state can exhibit spontaneous symmetry breaking when a control parameter exceeds a critical value. In this stud…
Error Performance of Rectangular Pulse-shaped OTFS with Practical Receivers
Cheng Shen, Jinhong Yuan, Hai Lin
In this letter, we investigate error performance of rectangular pulse-shaped orthogonal time frequency space (OTFS) modulation with a practical receiver. Specifically, we consider…
Impact of multiple modes on the evolution of self-interacting axion condensate around rotating black holes
Hidetoshi Omiya, Takuya Takahashi, Takahiro Tanaka +1
Ultra-light particles, such as axions, form a macroscopic condensate around a highly spinning black hole by the superradiant instability. Due to its macroscopic nature, the condens…
Quasiparticles of Decoherence Processes in Open Quantum Many-Body Systems: Incoherentons
Taiki Haga, Masaya Nakagawa, Ryusuke Hamazaki +1
The relaxation dynamics of an open quantum system is determined by the competition between the coherent Hamiltonian dynamics of a system and the dissipative dynamics due to interac…

Naoyuki Haba, Toshifumi Yamada
The SUSY GUT is in severe tension with the experimental bounds on proton partial lifetimes because proton decay mediated by colored Higgsinos (dimension-five proton decay)…

Density profiles near nuclear surface of Ti: An indication of clustering
W. Horiuchi, N. Itagaki
We investigate the degree of (He nucleus) clustering in the ground-state density profiles of Ti and Ti. Two types of density distributions, shell- and cluster…
Strong phase coherence and vortex matter in a fractal system with proximity-induced superconductivity
Nanami Teramachi, Aoi Hashimoto, Iku Nakaaki +10
The proximity effect in normal/superconductor heterostructures is an intriguing phenomenon in that the normal side takes on the properties of a superconductor with an induced gap.…
