Zero energy modes with Gaussian, exponential, or polynomial decay: Exact solutions in hermitian and nonhermitian regimes

Pasquale Marra, Angela Nigro

Topological zero modes in topological insulators or superconductors are exponentially localized at the phase transition between a topologically trivial and nontrivial phase. These…

Monopole-vortex continuity of $N = 1$ super Yang-Mills theory on $R^{2} \times S^{1} \times S^{1}$ with 't Hooft twist

Yui Hayashi, Tatsuhiro Misumi, Yuya Tanizaki

We study $N = 1$ $S U (N)$ super Yang-Mills (SYM) theory on $R^{2} \times (S^{1})_{3} \times (S^{1})_{4}$ with the 't Hooft twist. The theory becomes weakly coupled if the le…

Exact WKB in all sectors I: Potentials with degenerate saddles

Tatsuhiro Misumi, Cihan Pazarbaşı

We explore the exact-WKB (EWKB) method through the analysis of Airy and Weber types, with an emphasis on the exact quantization of locally harmonic potentials in multiple sectors.…

Quantum Hall liquids in high-density QCD

Kentaro Nishimura, Naoki Yamamoto, Ryo Yokokura

There exist metastable domain walls of the flavor-singlet meson $η$ for the $U (1)$ axial symmetry in two-flavor color superconductivity (2SC) in QCD at large baryon density.…

Topological zero modes and bounded modes at smooth domain walls: Exact solutions and dualities

Pasquale Marra, Angela Nigro

Topology describes global quantities invariant under continuous deformations, such as the number of elementary excitations at a phase boundary, without detailing specifics. Convers…

Spin Statistics and Surgeries of Topological Solitons in QCD Matter in Magnetic Field

Yuki Amari, Muneto Nitta, Ryo Yokokura

The ground state of QCD with two flavors (up and down quarks) at finite baryon density in sufficiently strong magnetic field is in a form of either a chiral soliton lattice(CSL), a…

Solitonic ground state in supersymmetric theory in background

Muneto Nitta, Shin Sasaki

A solitonic ground state called a chiral soliton lattice (CSL) is realized in a supersymmetric theory with background magnetic field and finite chemical potential. To this end, we…

Stringy constraints on primordial electromagnetic fields in axion inflation

Hajime Otsuka, Ryo Yokokura

We study primordial electromagnetic fields in effective actions of string theory. In contrast to a conventional scenario of producing primordial electromagnetic fields induced by t…
