Competing effects of interactions and spin-orbit coupling in a quantum wire
V. Gritsev, G. I. Japaridze, M. Pletyukhov +1
We study the interplay of electron-electron interactions and Rashba spin-orbit coupling in one-dimensional ballistic wires. Using the renormalization group approach we construct th…

The Biderivative and A_\infty-bialgebras
Samson Saneblidze, Ronald Umble
An A_\infty-bialgebra is a DGM H equipped with structurally compatible operations {ω^{j,i} : H^{\otimes i} --> H^{\otimes j}} such that (H,ω^{1,i}) is an A_\infty-algebra and (H,ω^…
