Generalized Pauli-Gursey transformation and Majorana neutrinos
Kazuo Fujikawa
We discuss a generalization of the Pauli-Gursey transformation, which is motivated by the Autonne-Takagi factorization, to an arbitrary number of generations of neutrinos using…
Consistency between Lüscher's finite volume method and HAL QCD method for two-baryon systems in lattice QCD
Takumi Iritani, Sinya Aoki, Takumi Doi +6
There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlator and the HAL QCD meth…
Quantum annealing for systems of polynomial equations
Chia Cheng Chang, Arjun Gambhir, Travis S. Humble +1
Numerous scientific and engineering applications require numerically solving systems of equations. Classically solving a general set of polynomial equations requires iterative solv…
Discrepancy in tidal deformability of GW170817 between the Advanced LIGO twin detectors
Tatsuya Narikawa, Nami Uchikata, Kyohei Kawaguchi +4
We find that the Hanford and Livingston detectors of Advanced LIGO derive a distinct posterior probability distribution of binary tidal deformability tilde{Lambda} of the first bin…
3D MHD modeling of the expanding remnant of SN 1987A. Role of magnetic field and non-thermal radio emission
S. Orlando, M. Miceli, O. Petruk +8
Aims. We investigate the role played by a pre-supernova (SN) ambient magnetic field on the dynamics of the expanding remnant of SN 1987A and the origin and evolution of the radio e…
Sensitivity of nuclear statistical equilibrium to nuclear uncertainties during stellar core collapse
Shun Furusawa
I have systematically investigated the equations of state (EOSs) in nuclear statistical equilibrium under thermodynamic conditions relevant for core collapse of massive stars by va…
Experimental measurement of the quantum geometric tensor using coupled qubits in diamond
Min Yu, Pengcheng Yang, Musang Gong +9
Geometry and topology are fundamental concepts, which underlie a wide range of fascinating physical phenomena such as topological states of matter and topological defects. In quant…
Seesaw mechanism and pseudo C-symmetry
Kazuo Fujikawa, Anca Tureanu
It is shown that the specific "charge conjugation" transformation used to define the Majorana fermions in the conventional seesaw mechanism, namely f…
Detection of Coronal Magnetic Activity in Nearby Active Supermassive Black Holes
Yoshiyuki Inoue, Akihiro Doi
Central supermassive black holes of active galactic nuclei host hot plasma with a temperature of K, namely coronae. Like the Sun, black hole coronae are theoretically believ…
Effect of Inhomogeneity on Primordial Black Hole Formation in the Matter Dominated Era
Takafumi Kokubu, Koutarou Kyutoku, Kazunori Kohri +1
We investigate the effect of inhomogeneity on primordial black hole formation in the matter dominated era. In the gravitational collapse of an inhomogeneous density distribution, a…
On the Neutrino Distributions in Phase Space for the Rotating Core-collapse Supernova Simulated with a Boltzmann-neutrino-radiation-hydrodynamics Code
Akira Harada, Hiroki Nagakura, Wakana Iwakami +5
With the Boltzmann-radiation-hydrodynamics code, which we have developed to solve numerically the Boltzmann equations for neutrino transfer, the Newtonian hydrodynamics equations,…
Linear confinement and stress-energy tensor around static quark and anti-quark pair -- Lattice simulation with Yang-Mills gradient flow --
Ryosuke Yanagihara, Takumi Iritani, Masakiyo Kitazawa +2
We study the spatial distribution of the stress tensor around static quark-anti-quark pair in SU(3) lattice gauge theory. In particular, we reveal the transverse structure of the s…
dibaryon from lattice QCD near the physical point
Takumi Iritani, Sinya Aoki, Takumi Doi +8
The nucleon()-Omega() system in the S-wave and spin-2 channel (S) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses (~MeV…
Deep Learning and Holographic QCD
Koji Hashimoto, Sotaro Sugishita, Akinori Tanaka +1
We apply the relation between deep learning (DL) and the AdS/CFT correspondence to a holographic model of QCD. Using a lattice QCD data of the chiral condensate at a finite tempera…
Systematic effects from black hole-neutron star waveform model uncertainties on the neutron star equation of state
Kabir Chakravarti, Anuradha Gupta, Sukanta Bose +12
We identify various contributors of systematic effects in the measurement of the neutron star (NS) tidal deformability and quantify their magnitude for several types of neutron sta…
The origin of polarization in kilonovae and the case of the gravitational-wave counterpart AT 2017gfo
M. Bulla, S. Covino, K. Kyutoku +8
The Gravitational Wave (GW) event GW 170817 was generated by the coalescence of two neutron stars (NS) and produced an electromagnetic transient, labelled AT 2017gfo, that was targ…
QCD Sum Rule for Open Strange Meson in Nuclear Matter
Taesoo Song, Tetsuo Hatsuda, Su Houng Lee
The properties of open strange meson in nuclear matter are estimated in the QCD sum rule approach. We obtain a relation between the in-medium mass and width of ($…
Tilted and type-III Dirac cones emerging from flat bands in photonic orbital graphene
M. Milićević, G. Montambaux, T. Ozawa +6
The extraordinary electronic properties of Dirac materials, the two-dimensional partners of Weyl semimetals, arise from the linear crossings in their band structure. When the dispe…
Back Reaction of 4D Conformal Fields on Static Geometry
Pei-Ming Ho, Hikaru Kawai, Yoshinori Matsuo +1
Static, spherically symmetric solutions to the semi-classical Einstein equation are studied, including the effect of the quantum energy-momentum tensor for conformal matters with 4…
