Reduction of the energy-gap scaling by coherent catalysis in models of quantum annealing
Yang Wei Koh, Hidetoshi Nishimori
Non-stoquastic drivers are known to improve the performance of quantum annealing by reducing first-order phase transitions into second-order ones in several mean-field-type model s…
Hydrodynamic simulations unravel the progenitor-supernova-remnant connection in SN 1987A
S. Orlando, M. Ono, S. Nagataki +8
(Abridged) We aim at linking the dynamical and radiative properties of the remnant of SN 1987A to the geometrical and physical characteristics of the parent aspherical SN explosion…
and N interactions from Lattice QCD near the physical point
Kenji Sasaki, Sinya Aoki, Takumi Doi +8
The -wave and interactions are studied on the basis of the (2+1)-flavor lattice QCD simulations close to the physical point ( and $m_K \simeq…
Fermion doubling theorems in 2D non-Hermitian systems for Fermi points and exceptional points
Zhesen Yang, A. P. Schnyder, Jiangping Hu +1
The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. H…
Reverse quantum annealing of the -spin model with relaxation
Gianluca Passarelli, Ka-Wa Yip, Daniel A. Lidar +2
In reverse quantum annealing, the initial state is an eigenstate of the final problem Hamiltonian and the transverse field is cycled rather than strictly decreased as in standard (…
Many-body scar state intrinsic to periodically driven system: Rigorous results
Sho Sugiura, Tomotaka Kuwahara, Keiji Saito
The violation of the Floquet version of eigenstate thermalization hypothesis is systematically discussed with realistic Hamiltonians. Our model is based on the PXP type interaction…
Intersubjectivity and value reproducibility of outcomes of quantum measurements
Masanao Ozawa
Every measurement determines a single value as its outcome, and yet quantum mechanics predicts it only probabilistically. The Kochen-Specker theorem and Bell's inequality are often…
Performance enhancement of quantum annealing under the Lechner-Hauke-Zoller scheme by non-linear driving of the constraint term
Yuki Susa, Hidetoshi Nishimori
We analyze the performance of quantum annealing as formulated by Lechner, Hauke, and Zoller (LHZ), by which a Hamiltonian with all-to-all two-body interactions is reduced to a corr…
Topologies on schemes and modulus pairs
Bruno Kahn, Hiroyasu Miyazaki
We study relationships between the Nisnevich topology on smooth schemes and certain Grothendieck topologies on proper and not necessarily proper modulus pairs which were introduced…
Strictly linear light cones in long-range interacting systems of arbitrary dimensions
Tomotaka Kuwahara, Keiji Saito
In locally interacting quantum many-body systems, the velocity of information propagation is finitely bounded and a linear light cone can be defined. Outside the light cone, the am…
Lattice gauge theory for Haldane conjecture and central-branch Wilson fermion
Tatsuhiro Misumi, Yuya Tanizaki
We develop the d lattice gauge theory in order to define -flavor massless Schwinger model, and discuss its connection with Haldane conjecture. We propose to use th…
Clustering of conditional mutual information for quantum Gibbs states above a threshold temperature
Tomotaka Kuwahara, Kohtaro Kato, Fernando G. S. L. Brandão
We prove that the quantum Gibbs states of spin systems above a certain threshold temperature are approximate quantum Markov networks, meaning that the conditional mutual informatio…
Reanalysis of the binary neutron star mergers GW170817 and GW190425 using numerical-relativity calibrated waveform models
Tatsuya Narikawa, Nami Uchikata, Kyohei Kawaguchi +4
We reanalyze gravitational waves from binary-neutron-star mergers GW170817 and GW190425 using a numerical-relativity (NR) calibrated waveform model, the TF2+_Kyoto model, which inc…
Operatorial characterization of Majorana neutrinos
Kazuo Fujikawa
The Majorana neutrino when constructed as a superposition of chiral fermions such as is characterized by $ ({\cal C}{\cal P}) ψ_{M}(x)({\…
Possible lightest Hypernucleus with Modern Interactions
E. Hiyama, K. Sasaki, T. Miyamoto +4
Experimental evidence exists that the -nucleus interaction is attractive. We search for and bound systems on the basis of the AV8 potential combined with eithe…
Enrichment of Strontium in Dwarf Galaxies
Yutaka Hirai, Shinya Wanajo, Takayuki R. Saitoh
Light trans-iron elements such as Sr serve as the key to understanding the astrophysical sites of heavy elements. Spectroscopic studies of metal-poor stars have revealed large star…
A new magnetic monopole inspired by Berry's phase
Shinichi Deguchi, Kazuo Fujikawa
A new static and azimuthally symmetric magnetic monopolelike object, which looks like a Dirac monopole when seen from far away but smoothly changes to a dipole near the monopole po…
Curve counting via stable objects in derived categories of Calabi-Yau 4-folds
Yalong Cao, Yukinobu Toda
In our previous paper with Maulik, we proposed a conjectural Gopakumar-Vafa (GV) type formula for the generating series of stable pair invariants on Calabi-Yau (CY) 4-folds. The pu…
Thermal phase transition in Yang-Mills matrix model
Georg Bergner, Norbert Bodendorfer, Masanori Hanada +3
We study the bosonic matrix model obtained as the high-temperature limit of two-dimensional maximally supersymmetric SU() Yang-Mills theory. So far, no consensus about the order…
On the Origin of High Energy Neutrinos from NGC 1068: The Role of Non-Thermal Coronal Activity
Yoshiyuki Inoue, Dmitry Khangulyan, Akihiro Doi
NGC 1068, a nearby type-2 Seyfert galaxy, is reported as the hottest neutrino spot in the 10-year survey data of IceCube. Although there are several different possibilities for the…
Hermitizing the HAL QCD potential in the derivative expansion
Sinya Aoki, Takumi Iritani, Koichi Yazaki
A formalism is given to hermitize the HAL QCD potential, which needs to be non-hermitian except the leading order (LO) local term in the derivative expansion as the Nambu-Bethe-Sal…
Probing and dibaryons with femtoscopic correlations in relativistic heavy-ion collisions
Kenji Morita, Shinya Gongyo, Tetsuo Hatsuda +3
The momentum correlation functions of baryon pairs, which reflects the baryon-baryon interaction at low energies, are investigated for multi-strangeness pairs ( and ) produ…
