The Normality of Certain Varieties of Special Lattices
William Haboush, Akira Sano
We begin with a short exposition of the theory of lattice varieties. This includes a description of their orbit structure and smooth locus. We construct a flat cover of the lattice…
Gorenstein and normal properties of the subregular variety of a variety of special lattices over Witt vectors
Akira Sano
We recall the projective variety parametrizing a family of special lattices over Witt vectors. It is normal and Gorenstein. In this article, we prove that there exists a particular…
Interference Effect in Multi-level Transport through a Quantum Dot
Hisashi Aikawa, Kensuke Kobayashi, Akira Sano +2
We present experimental results and a model to solve the problem of "in-phase Coulomb peaks" observed in transport through a quantum dot. In a marginal region between Coulomb-block…
Fano Resonance in a Quantum Wire with a Side-coupled Quantum Dot
Kensuke Kobayashi, Hisashi Aikawa, Akira Sano +2
We report a transport experiment on the Fano effect in a quantum connecting wire (QW) with a side-coupled quantum dot (QD). The Fano resonance occurs between the QD and the "T-shap…
Observation of "Partial Coherence" in an Aharonov-Bohm Interferometer with a Quantum Dot
Hisashi Aikawa, Kensuke Kobayashi, Akira Sano +2
We report experiments on the interference through spin states of electrons in a quantum dot (QD) embedded in an Aharonov-Bohm (AB) interferometer. We have picked up a spin-pair sta…
