Dynamical AdS strings across horizons
Takaaki Ishii, Keiju Murata
We examine the nonlinear classical dynamics of a fundamental string in anti-de Sitter spacetime. The string is dual to the flux tube between an external quark-antiquark pair in $\m…
Semiprojectivity and properly infinite projections in graph C*-algebras
Søren Eilers, Takeshi Katsura
We give a complete description of which unital graph C*-algebras are semiprojective, and use it to disprove two conjectures by Blackadar. To do so, we perform a detailed analysis o…
Inhomogeneous chiral phases in two-flavor quark matter
Hiroaki Abuki
We present a systematic study of the phase structure of QCD in a generalized Ginzburg-Landau framework. We find, going up in density, a strongly interacting matter might go through…
Signature of an Intermediate-Mass Black Hole in the Central Molecular Zone of Our Galaxy
Tomoharu Oka, Reiko Mizuno, Kodai Miura +1
We mapped the high-velocity compact cloud CO-0.40-0.22 in 21 molecular lines in the 3 mm band using the Nobeyama Radio Observatory 45 m radio telescope. Eighteen lines were detecte…
Non-Abelian chiral instabilities at high temperature on the lattice
Yukinao Akamatsu, Alexander Rothkopf, Naoki Yamamoto
We report on an exploratory lattice study on the phenomenon of chiral instabilities in non-Abelian gauge theories at high temperature. It is based on a recently constructed anomalo…
Magnetic Properties of Quantized Vortices in Neutron Superfluids in Neutron Stars
Kota Masuda, Muneto Nitta
We discuss quantized vortices in neutron superfluids, which are believed to realize in high density neutron matter such as neutron stars. By using the Ginzburg-Landau free…
Designing a Million-Qubit Quantum Computer Using Resource Performance Simulator
Muhammad Ahsan, Rodney Van Meter, Jungsang Kim
The optimal design of a fault-tolerant quantum computer involves finding an appropriate balance between the burden of large-scale integration of noisy components and the load of im…
Energy current cumulants in one-dimensional systems in equilibrium
Abhishek Dhar, Keiji Saito, Anjan Roy
Recently a remarkable connection has been proposed between the fluctuating hydrodynamic equations of a one-dimensional fluid and the Kardar-Parizi-Zhang (KPZ) equation for interfac…
Quiver W-algebras
Taro Kimura, Vasily Pestun
For a quiver with weighted arrows we define gauge-theory K-theoretic W-algebra generalizing the definition of Shiraishi et al., and Frenkel and Reshetikhin. In particular, we show…
Exhaustive derivation of static self-consistent multi-soliton solutions in the matrix Bogoliubov-de Gennes systems
Daisuke A. Takahashi
The matrix-generalized Bogoliubov-de Gennes systems have recently been considered by the present author [arXiv:1509.04242, Phys. Rev. B 93, 024512 (2016)], and time-dependent and s…
A supersymmetric Skyrme model
Sven Bjarke Gudnason, Muneto Nitta, Shin Sasaki
Construction of a supersymmetric extension of the Skyrme term was a long-standing problem because of the auxiliary field problem; that is, the auxiliary field may propagate and can…
Semilocal Fractional Instantons
Minoru Eto, Muneto Nitta
We find semi-local fractional instantons of codimension four in Abelian and non-Abelian gauge theories coupled with scalar fields and the corresponding and Gra…
Aharonov-Bohm Phase in High Density Quark Matter
Chandrasekhar Chatterjee, Muneto Nitta
Stable non-Abelian vortices, which are color magnetic flux tubes as well as superfluid vortices, are present in the color-flavor locked phase of dense quark matter with diquark con…
Axion electrodynamics and nonrelativistic photons in nuclear and quark matter
Naoki Yamamoto
We argue that the effective theory for electromagnetic fields in spatially varying meson condensations in dense nuclear and quark matter is given by the axion electrodynamics. We s…
Semi-doubled Sigma Models for Five-branes
Tetsuji Kimura
We study two-dimensional gauge theory and its dualized system in terms of complex (linear) superfields and their alternatives. Although this technique itself is no…
Light Curve Analysis of Neon Novae
Izumi Hachisu, Mariko Kato
We analyzed light curves of five neon novae, QU Vul, V351 Pup, V382 Vel, V693 CrA, and V1974 Cyg, and determined their white dwarf (WD) masses and distance moduli on the basis of t…
Evolution of Cooper pairs with zero-center-of-mass momentum and their first-order correlation function in a two-dimensional ultracold Fermi gas near the observed Berezinskii-Kosterlitz-Thouless transition
Morio Matsumoto, Daisuke Inotani, Yoji Ohashi
We investigate the center-of-mass momentum distribution of Cooper pairs and their first-order correlation function in a strongly interacting two-dimens…
Chiral transport of neutrinos in supernovae: Neutrino-induced fluid helicity and helical plasma instability
Naoki Yamamoto
Chirality of neutrinos modifies the conventional kinetic theory and hydrodynamics, leading to unusual chiral transport related to quantum anomalies in field theory. We argue that t…
Magnetization process of spin-1/2 Heisenberg antiferromagnets on a layered triangular lattice
Daisuke Yamamoto, Giacomo Marmorini, Ippei Danshita
We study the magnetization process of the spin-1/2 antiferromagnetic Heisenberg model on a layered triangular lattice by means of a numerical cluster mean-field method with a scali…
Strong-coupling corrections to spin susceptibility in the BCS-BEC crossover regime of a superfluid Fermi gas
H. Tajima, R. Hanai, Y. Ohashi
We theoretically investigate the uniform spin susceptibility in the superfluid phase of an ultracold Fermi gas in the BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condens…
Gravitating BPS Skyrmions
Sven Bjarke Gudnason, Muneto Nitta, Nobuyuki Sawado
The BPS Skyrme model has many exact analytic solutions in flat space. We generalize the model to a curved space or spacetime and find that the solutions can only be BPS for a const…
Umbrella-coplanar transition in the triangular XXZ model with arbitrary spin
Giacomo Marmorini, Daisuke Yamamoto, Ippei Danshita
The quantum triangular XXZ model has recently enjoyed a wealth of new theoretical results, especially in relation to the modeling of the BaCoSbO compound. In particular…
Fluctuation Amplitude of a Trapped Rigid Sphere Immersed in a Near-Critical Binary Fluid Mixture within the Regime of the Gaussian Model
Youhei Fujitani
The position of a colloidal particle trapped in an external field thermally fluctuates at equilibrium. As is well known, the ambient fluid is not a simple heat bath and the particl…
Undulation Amplitude of a Fluid Membrane in a Near-Critical Binary Fluid Mixture Calculated beyond the Gaussian Model Supposing Weak Preferential Attraction
Youhei Fujitani
We calculate the mean square amplitude of the shape fluctuation -- an equal-time correlation -- of an almost planar fluid membrane immersed in a near-critical binary fluid mixture.…
