Effects of Disorder on Coexistence and Competition between Superconducting and Insulating States
M. V. Mostovoy, F. M. Marchetti, B. D. Simons +1
We study effects of nonmagnetic impurities on the competition between the superconducting and electron-hole pairing. We show that disorder can result in coexistence of these two ty…
Spin-Isospin Model of NaV_2O_5
M. V. Mostovoy, J. Knoester, D. I. Khomskii
We argue that in the quarter-filled ladder compound NaV_2O_5 the quasi-one-dimensional spin system is strongly coupled to a low-energy antiferroelectric mode of the excitonic type.…
Peierls transition with acoustic phonons and twist deformation in carbon nanotubes
Marc Thilo Figge, Maxim Mostovoy, Jasper Knoester
We consider the Peierls instability due to the interaction of electrons with both acoustic and optical phonons. We suggest that such a transition takes place in carbon nanotubes wi…
Disorder-induced neutral solitons in degenerate ground state polymers
Marc Thilo Figge, Maxim V. Mostovoy, Jasper Knoester
In this letter, we study the effects of weak off-diagonal disorder on conjugated polymers with a doubly degenerate ground-state. We find that disorder induces a finite density of n…
Solitons and (spin-)Peierls transition in disordered quasi-one-dimensional systems
M. Mostovoy, D. Khomskii
We study the (spin-)Peierls transition in quasi-one-dimensional disordered systems, treating the lattice classically. The role of kinks, induced thermally and by disorder, is empha…
