Non-symmetric class association schemes obtained by doubling of skew-Hadamard matrices are non-schurian
Akihide Hanaki
We can obtain a non-symmetric class association scheme by a skew-Hadamard matrix. We begin with a skew-Hadamard matrix of order , construct a skew-Hadamard matrix of order $…
The Witten Index for One-dimensional Non-unitary Quantum Walks with Gapless Time-evolution
Keisuke Asahara, Daiju Funakawa, Motoki Seki +1
Recent developments in the index theory of discrete-time quantum walks allow us to assign a certain well-defined supersymmetric index to a pair of a unitary time-evolution and…
Universal function of the non-equilibrium phase transition of nonlinear Pólya urn
Kazuaki Nakayama, Shintaro Mori
We study the phase transition and the critical properties of a nonlinear Pólya urn, which is a simple binary stochastic process with a feedback mechani…
Origin of Weak MgII and Higher Ionization Absorption Lines in an Outflow from an Intermediate-Redshift Dwarf Satellite Galaxy
Akimi Fujita, Toru Misawa, Jane C. Charlton +2
Observations at intermediate redshifts reveal the presence of numerous, compact, weak MgII absorbers with near to super-solar metallicities, often surrounded by more extended regio…
Spectral analysis for a multi-dimensional split-step quantum walk with a defect
Toru Fuda, Akihiro Narimatsu, Kei Saito +1
This paper studies the spectrum of a multi-dimensional split-step quantum walk with a defect that cannot be analysed in the previous papers. To this end, we have developed a new te…
First-principles study of the stability of bimetallic PdPt nanoparticles under a finite temperature
Takayoshi Ishimoto, Michihisa Koyama
To understand the vibrational and configurational entropy effects for the stability of core-shell and solid-solution bimetallic nanoparticles, we theoretically investigated the exc…
