Dyon Condensation at from Wilson-'t Hooft Loops in Yang-Mills Theory
Hiromasa Watanabe, Issaku Kanamori, Okuto Morikawa +3
Although Yang--Mills theories at and are physically equivalent, their periodicity is realized nontrivially in the presence of a background field for the -form center…
Numerical Hints for Dyon Condensation at via Wilson-'t Hooft Loops in Yang-Mills Theory
Hiromasa Watanabe, Issaku Kanamori, Okuto Morikawa +3
Yang-Mills theories at and are unitarily equivalent, but their periodicity has a nontrivial realization. Recent developments in generalized symmetries rigorously pr…
Tensor renormalization group approach to the models via symmetry-twisted partition functions
Shinichiro Akiyama, Raghav G. Jha, Jun Maeda +2
We investigate critical phenomena in the models using symmetry-twisted partition functions that can be efficiently computed within the tensor renormalization group framework…
Tensor renormalization group approach to critical phenomena via symmetry-twisted partition functions
Shinichiro Akiyama, Raghav G. Jha, Jun Maeda +2
The locality of field theories strongly constrains the possible behaviors of symmetry-twisted partition functions, and thus they serve as order parameters to detect low-energy real…
Computing theta-dependent mass spectrum of the 2-flavor Schwinger model in the Hamiltonian formalism
Akira Matsumoto, Etsuko Itou, Yuya Tanizaki
We compute the -dependent mass spectrum of the 2-flavor Schwingr model using the tensor network (DMRG) in the Hamiltonian formalism. The pion and the sigma meson are identified…
Lattice gradient flows (de-)stabilizing topological sectors
Yuya Tanizaki, Akio Tomiya, Hiromasa Watanabe
We investigate the stability of topological charge under gradient flow taking the admissibility condition into account. For the Wilson gauge theory with and $L^4=1…
DMRG study of the theta-dependent mass spectrum in the 2-flavor Schwinger model
Etsuko Itou, Akira Matsumoto, Yuya Tanizaki
We study the -dependent mass spectrum of the massive -flavor Schwinger model in the Hamiltonian formalism using the density-matrix renormalization group(DMRG). The masses of…
Three ways of calculating mass spectra for the 2-flavor Schwinger model in the Hamiltonian formalism
Akira Matsumoto, Etsuko Itou, Yuya Tanizaki
We propose three independent methods to compute the hadron mass spectra of gauge theories in the Hamiltonian formalism. The determination of hadron masses is one of the key issues…
Lattice construction of mixed 't Hooft anomaly with higher-form symmetry
Motokazu Abe, Okuto Morikawa, Soma Onoda +2
In this talk, we give the lattice regularized formulation of the mixed 't Hooft anomaly between the -form symmetry and the periodicity for d pure Yang-Mill…
Calculating composite-particle spectra in Hamiltonian formalism and demonstration in 2-flavor QED
Etsuko Itou, Akira Matsumoto, Yuya Tanizaki
We consider three distinct methods to compute the mass spectrum of gauge theories in the Hamiltonian formalism: (1) correlation-function scheme, (2) one-point-function scheme, and…
Magnetic operators in 2D compact scalar field theories on the lattice
Motokazu Abe, Okuto Morikawa, Soma Onoda +2
In lattice compact gauge theories, we must impose the admissibility condition to have well-defined topological sectors. The admissibility condition, however, usually forbids the pr…
Topology of lattice gauge theories coupled with -form gauge fields
Motokazu Abe, Okuto Morikawa, Soma Onoda +2
We extend the definition of Lüscher's lattice topological charge to the case of d gauge fields coupled with -form gauge fields. This result is achieved…
DMRG study of the higher-charge Schwinger model and its 't Hooft anomaly
Masazumi Honda, Etsuko Itou, Yuya Tanizaki
The charge- Schwinger model is the -dimensional quantum electrodynamics (QED) with a charge- Dirac fermion. It has the -form symmetry and also enjoys…
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…
Gradient flows without blow-up for Lefschetz thimbles
Yuya Tanizaki, Hiromichi Nishimura, Jacobus J. M. Verbaarschot
We propose new gradient flows that define Lefschetz thimbles and do not blow up in a finite flow time. We study analytic properties of these gradient flows, and confirm them by num…
Lefschetz-thimble approach to the Silver Blaze problem of one-site fermion model
Yuya Tanizaki, Yoshimasa Hidaka, Tomoya Hayata
The sign problem of finite-density QCD at the zero temperature becomes very severe if the quark chemical potential exceeds half of the pion mass. In order to understand its propert…
Complex saddle points and the sign problem in complex Langevin simulation
Tomoya Hayata, Yoshimasa Hidaka, Yuya Tanizaki
We show that complex Langevin simulation converges to a wrong result, by relating it to the Lefschetz-thimble path integral, when the path-integral weight has different phases amon…
