Violation of the Leggett-Garg inequality in photon-graviton conversion
Kimihiro Nomura, Akira Taniguchi, Kazushige Ueda
The Leggett-Garg inequality (LGI) is a temporal analogue of Bell's inequality and provides a quantitative test of the nonclassicality of a system through its violation. We analytic…
On the validity of the complex Langevin method near the deconfining phase transition in QCD at finite density
Shoichiro Tsutsui, Yuhma Asano, Yuta Ito +5
In our previous paper [JHEP 10 (2020) 144], we found that the complex Langevin (CL) method works for QCD at finite density on the lattice in the low-temperature hi…
Imprints of Dark Photons on Gravitational Wave Polarizations
Kimihiro Nomura, Jiro Soda, Kazushige Ueda +1
We study conversion processes between gravitons and dark photons and reveal the effects of dark photons on the polarization of gravitational waves. Considering cosmological dark ma…
Color superconductivity on the lattice -- analytic predictions from QCD in a small box
Takeru Yokota, Yuta Ito, Hideo Matsufuru +4
We investigate color superconductivity on the lattice using the gap equation for the Cooper pair condensate. The weak coupling analysis is justified by choosing the physical size o…
CDT and Horava-Lifshitz QG in Two Dimensions
Yuki Sato
The two-dimensional causal dynamical triangulations (d CDT) is a lattice model of quantum geometry. In d CDT, one can deal with the quantum effects analytically and explore t…
Progress in the numerical studies of the type IIB matrix model
Konstantinos N. Anagnostopoulos, Takehiro Azuma, Kohta Hatakeyama +5
The type IIB matrix model, also known as the IKKT model, has been proposed as a promising candidate for a non-perturbative formulation of superstring theory. Based on this proposal…
Tensor network approach to 2d Lorentzian quantum Regge calculus
Yoshiyasu Ito, Daisuke Kadoh, Yuki Sato
We demonstrate a tensor renormalization group (TRG) calculation for a two-dimensional Lorentzian model of quantum Regge calculus (QRC). This model is expressed in terms of a tensor…
Complex Langevin studies of the emergent space-time in the type IIB matrix model
Kohta Hatakeyama, Konstantinos Anagnostopoulos, Takehiro Azuma +5
The type IIB matrix model has been proposed as a non-perturbative definition of superstring theory since 1996. We study a simplified model that describes the late time behavior of…
HumanACGAN: conditional generative adversarial network with human-based auxiliary classifier and its evaluation in phoneme perception
Yota Ueda, Kazuki Fujii, Yuki Saito +3
We propose a conditional generative adversarial network (GAN) incorporating humans' perceptual evaluations. A deep neural network (DNN)-based generator of a GAN can represent a rea…
Surface localization of the dineutron in Li
Y. Kubota, A. Corsi, G. Authelet +64
The formation of a dineutron in the nucleus Li is found to be localized to the surface region. The experiment measured the intrinsic momentum of the struck neutron in $^{11}…
Complex Langevin calculations in QCD at finite density
Yuta Ito, Hideo Matsufuru, Yusuke Namekawa +4
We demonstrate that the complex Langevin method (CLM) enables calculations in QCD at finite density in a parameter regime in which conventional methods, such as the density of stat…
Complex Langevin analysis of the spontaneous breaking of 10D rotational symmetry in the Euclidean IKKT matrix model
Konstantinos N. Anagnostopoulos, Takehiro Azuma, Yuta Ito +3
The IKKT matrix model is a promising candidate for a nonperturbative formulation of superstring theory, in which spacetime is conjectured to emerge dynamically from the microscopic…
Stable Training of DNN for Speech Enhancement based on Perceptually-Motivated Black-Box Cost Function
Masaki Kawanaka, Yuma Koizumi, Ryoichi Miyazaki +1
Improving subjective sound quality of enhanced signals is one of the most important missions in speech enhancement. For evaluating the subjective quality, several methods related t…
HumanGAN: generative adversarial network with human-based discriminator and its evaluation in speech perception modeling
Kazuki Fujii, Yuki Saito, Shinnosuke Takamichi +2
We propose the HumanGAN, a generative adversarial network (GAN) incorporating human perception as a discriminator. A basic GAN trains a generator to represent a real-data distribut…
Azimuthal angle distributions of neutrons emitted from the Be(,) reaction with linearly polarized -rays
Yuma Kikuchi, Kazuyuki Ogata, Takehito Hayakawa +1
The electromagnetic transitions of Be with linearly polarized -rays are calculated by using the ~+~~+~ three-body model and the complex-scaled solutions of the Lipp…
A Quantum-like Model of Selection Behavior
Masanari Asano, Irina Basieva, Andrei Khrennikov +2
In this paper, we introduce a new model of selection behavior under risk that describes an essential cognitive process for comparing values of objects and making a selection decisi…
Violation of contextual generalization of the Leggett-Garg inequality for recognition of ambiguous figures
Masanari Asano, Takahisa Hashimoto, Andrei Khrennikov +2
We interpret the Leggett-Garg (LG) inequality as a kind of contextual probabilistic inequality in which one combines data collected in experiments performed for three different con…
