Investigation of complex theory at finite density in two dimensions using TRG
Daisuke Kadoh, Yoshinobu Kuramashi, Yoshifumi Nakamura +3
We study the two-dimensional complex theory at finite chemical potential using the tensor renormalization group. This model exhibits the Silver Blaze phenomenon in which bu…
Effective Data Augmentation with Multi-Domain Learning GANs
Shin'ya Yamaguchi, Sekitoshi Kanai, Takeharu Eda
For deep learning applications, the massive data development (e.g., collecting, labeling), which is an essential process in building practical applications, still incurs seriously…
modified XY and Goldstone models and vortex confinement transition
Michikazu Kobayashi, Muneto Nitta
The modified XY model is a modification of the XY model by addition of a half-periodic term. The modified Goldstone model is a regular and continuum version of the modified XY mode…
Collision dynamics and reactions of fractional vortex molecules in coherently coupled Bose-Einstein condensates
Minoru Eto, Kazuki Ikeno, Muneto Nitta
Coherently coupled two-component Bose-Einstein condensates (BEC) exhibit vortex confinement resembling quark confinement in Quantum Chromo Dynamics (QCD). Fractionally quantized vo…
An Adaptive Reaction Force Observer Design
Emre Sariyildiz, Kouhei Ohnishi
In this paper, a new adaptive design method is proposed for reaction force observer (RFOB) based robust force control systems. It is a well-known fact that an RFOB has several supe…
A Guide to Design Disturbance Observer
Emre Sariyildiz, Kouhei Ohnishi
The goal of this paper is to clarify the robustness and performance constraints in the design of control systems based on disturbance observer (DOB). Although the bandwidth constra…
Stability and Robustness of Disturbance Observer based Motion Control Systems
Emre Sariyildiz, Kouhei Ohnishi
This paper analyzes the robustness and stability of a disturbance observer (DOB) and a reaction torque observer (RTOB) based robust motion control systems. Conventionally, a DOB is…
A non-equilibrium quantum many-body Rydberg atom engine
Federico Carollo, Filippo M. Gambetta, Kay Brandner +2
The standard approach to quantum engines is based on equilibrium systems and on thermodynamic transformations between Gibbs states. However, non-equilibrium quantum systems offer e…
Instabilities in monoaxial chiral magnets under a tilted magnetic field
Yusuke Masaki
We thoroughly study the zero temperature properties of monoaxial chiral spin systems under a tilted magnetic field. The magnetic phase diagram includes two kinds of continuous phas…
Kondo effect driven by chirality imbalance
Daiki Suenaga, Kei Suzuki, Yasufumi Araki +1
We propose a novel mechanism of the Kondo effect driven by a chirality imbalance (or chiral chemical potential) of relativistic light fermions. This effect is realized by the mixin…
Transformation formulas of finite sums into continued fractions
Daniel Duverney, Takeshi Kurosawa, Iekata Shiokawa
We state and prove three general formulas allowing to transform formal finite sums into formal continued fractions and apply them to generalize certain expansions in continued frac…
Strong-coupling effects of pairing fluctuations, and Anderson-Bogoliubov mode in neutron S superfluids in neutron stars
Daisuke Inotani, Shigehiro Yasui, Muneto Nitta
We investigate effects of thermal and quantum fluctuations of the superfluid order parameter in superfluids in neutron stars. We construct a separable potential to reprod…
Remarks on the large- model
Antonino Flachi
In this paper, we consider the model confined to an interval of finite size at finite temperature and chemical potential. We obtain, in the large-N approximati…
Continuous Phase Transition without Gap Closing in Non-Hermitian Quantum Many-Body Systems
Norifumi Matsumoto, Kohei Kawabata, Yuto Ashida +2
Contrary to the conventional wisdom in Hermitian systems, a continuous quantum phase transition between gapped phases is shown to occur without closing the energy gap in non-He…
Kovtun-Son-Starinets Conjecture and Effects of Mass Imbalance in the Normal State of an Ultracold Fermi Gas in the BCS-BEC Crossover Region
Daichi Kagamihara, Yoji Ohashi
We theoretically assess the conjecture proposed by Kovtun, Son, and Starinets, stating that the ratio of the shear viscosity to the entropy density has the lower boun…
Emergent discrete 3-form symmetry and domain walls
Yoshimasa Hidaka, Muneto Nitta, Ryo Yokokura
We show that axion models with the domain wall number in dimensions, i.e., periodic scalar field theories admitting axion domain walls, exhibit an emergent ${\mathb…
Chemical bonds of two vortex species with a generalized Josephson term and arbitrary charges
Chandrasekhar Chatterjee, Sven Bjarke Gudnason, Muneto Nitta
We consider the Abelian-Higgs model with two complex scalar fields and arbitrary positive integer charges with the addition of a higher-order generalization of the Josephson term.…
Exploring the QCD phase diagram at finite density by the complex Langevin method on a lattice
Shoichiro Tsutsui, Yuta Ito, Hideo Matsufuru +3
We explore the QCD phase diagram at finite density with four-flavor staggered fermions using the complex Langevin method, which is a promising approach to overcome the sign problem…
Measurement of neutrino and antineutrino neutral-current quasielastic-like interactions on oxygen by detecting nuclear de-excitation -rays
K. Abe, R. Akutsu, A. Ali +330
Neutrino- and antineutrino-oxygen neutral-current quasielastic-like interactions are measured at Super-Kamiokande using nuclear de-excitation -rays to identify signal-like inter…

Junichiro Kawamura, Stuart Raby, Andreas Trautner
In this paper we present an in-depth analysis of a recently proposed Standard Model extension with a complete fourth generation of quarks and leptons, which are vector-like with re…
Dataflow programming for the analysis of molecular dynamics with AViS, an analysis and visualization software application
Kai Pua, Daisuke Yuhara, Sho Ayuba +1
The study of molecular dynamics simulations is largely facilitated by analysis and visualization toolsets. However, these toolsets are often designed for specific use cases and tho…
