Holographic Floquet states: (I) A strongly coupled Weyl semimetal
Koji Hashimoto, Shunichiro Kinoshita, Keiju Murata +1
Floquet states can be realized in quantum systems driven by continuous time-periodic perturbations. It is known that a state known as the Floquet Weyl semimetal can be realized whe…
Meissner effect and a stringlike interaction
Chandrasekhar Chatterjee, Ishita Dutta Choudhury, Amitabha Lahiri
We find that a recently proposed interaction involving the vorticity current of electrons, which radiatively induces a photon mass in 3+1 dimensions in the low-energy effective the…
Inflation from periodic extra dimensions
Tetsutaro Higaki, Yoshiyuki Tatsuta
We discuss a realization of a small field inflation based on string inspired supergravities. In theories accompanying extra dimensions, compactification of them with small radii is…
The fate of chaotic strings in a confining geometry
Takaaki Ishii, Keiju Murata, Kentaroh Yoshida
We study chaotic motion of classical closed strings in the five-dimensional Anti-de Sitter (AdS) soliton spacetime. We first revisit classical chaos using a cohomogeneity-1 string…
Abelian tensor hierarchy and Chern-Simons actions in 4D N=1 conformal supergravity
Ryo Yokokura
We consider Chern-Simons actions of Abelian tensor hierarchy of -form gauge fields in four-dimensional supergravity. Using conformal superspace formalism, we solve…
Chiral Shock Waves
Srimoyee Sen, Naoki Yamamoto
We study the shock waves in relativistic chiral matter. We argue that the conventional Rankine-Hugoinot relations are modified due to the presence of chiral transport phenomena. We…
Ghostbusters in higher derivative supersymmetric theories: who is afraid of propagating auxiliary fields?
Toshiaki Fujimori, Muneto Nitta, Yusuke Yamada
We present for the first time a ghost-free higher-derivative chiral model with a propagating auxiliary F-term field (highest component of the chiral multiplet). We obtain this mode…
Stabilizing semilocal strings by polarization
Minoru Eto, Muneto Nitta, Kohei Sakurai
Semilocal strings are vortices in the extended Abelian-Higgs model with two complex Higgs scalar fields among which a global symmetry acts. They are known to be stable (uns…
Quiver elliptic W-algebras
Taro Kimura, Vasily Pestun
We define elliptic generalization of W-algebras associated with arbitrary quiver using the formalism of arXiv:1512.08533 applied to six-dimensional quiver gauge theory compactified…
Topological solitons in the supersymmetric Skyrme model
Sven Bjarke Gudnason, Muneto Nitta, Shin Sasaki
A supersymmetric extension of the Skyrme model was obtained recently, which consists of only the Skyrme term in the Nambu-Goldstone (pion) sector complemented by the same number of…
Nonlocal N=1 Supersymmetry
Tetsuji Kimura, Anupam Mazumdar, Toshifumi Noumi +1
We construct supersymmetric nonlocal theories in four dimension. We discuss higher derivative extensions of chiral and vector superfields, and write down generic fo…
Non-perturbative Contributions from Complexified Solutions in Models
Toshiaki Fujimori, Syo Kamata, Tatsuhiro Misumi +2
We discuss the non-perturbative contributions from real and complex saddle point solutions in the quantum mechanics with fermionic degrees of freedom, using the Lef…
Skyrmions confined as beads on a vortex ring
Sven Bjarke Gudnason, Muneto Nitta
A very simple, quadratic potential is used to construct vortex strings in a generalized Skyrme model and an additional quadratic potential is used to embed sine-Gordon-type halfkin…
Radial vibrations of BPS skyrmions
C. Adam, M. Haberichter, T. Romanczukiewicz +1
We study radial vibrations of spherically symmetric skyrmions in the BPS Skyrme model. Concretely, we numerically solve the linearised field equations for small fluctuations in a s…

Syo Kamata, So Matsuura, Tatsuhiro Misumi +1
We investigate the two-dimensional supersymmetric Yang-Mills (SYM) theory on the discretized curved space (polyhedra). We first revisit that the number of super…
Abelian tensor hierarchy in 4D conformal supergravity
Shuntaro Aoki, Tetsutaro Higaki, Yusuke Yamada +1
We consider Abelian tensor hierarchy in four-dimensional supergravity in the conformal superspace formalism, where the so-called covariant approach is used to antisymm…
Chaos in chiral condensates in gauge theories
Koji Hashimoto, Keiju Murata, Kentaroh Yoshida
Assigning a chaos index for dynamics of generic quantum field theories is a challenging problem, because the notion of Lyapunov exponent, which is useful for singling out chaotic b…
Black hole Skyrmion in a generalized Skyrme model
Sven Bjarke Gudnason, Muneto Nitta, Nobuyuki Sawado
We study a Skyrme-like model with the Skyrme term and a sixth-order derivative term as higher-order terms, coupled to gravity and we construct Schwarzschild black hole Skyrme hair.…
Scattering Amplitude and Bosonization Duality in General Chern-Simons Vector Models
Shuichi Yokoyama
We present exact large N calculus of four point function in general Chern-Simons bosonic and fermionic vector models. Applying the LSZ formula to the four point function we determi…

Tatsuhiro Misumi, Muneto Nitta, Norisuke Sakai
We investigate non-BPS exact solutions in sigma models on with twisted boundary conditions, by using the Din-Zakrzewski projection…
Head butting sheep: Kink Collisions in the Presence of False Vacua
Jennifer Ashcroft, Minoru Eto, Mareike Haberichter +2
We investigate numerically kink collisions in a dimensional scalar field theory with multiple vacua. The domain wall model we are interested in involves two scalar fields and…
