Snyman, I. (author), Nazarov, Y.V. (author)We prove theoretically the possibility of electric-field controlled polaron formation involving flexural (bending) modes in suspended carbon nanotubes. Upon increasing the field, the ground state of the system with a single extra electron undergoes a first-order phase transition between an extended state and a localized polaron state. For a...journal article 2012

Snyman, I. (author), Nazarov, Y.V. (author)As a generic example of a voltage-driven superconducting structure, we study a short superconductor connected to normal leads by means of low transparency tunnel junctions with a voltage bias V between the leads. The superconducting order parameter ? is to be determined self-consistently. We study the stationary states as well as the dynamics...journal article 2009

Snyman, I. (author), Nazarov, Y.V. (author)We present a derivation of the Keldysh action of a general multichannel time-dependent scatterer in the context of the Landauer–Büttiker approach. The action is a convenient building block in the theory of quantum transport. This action is shown to take a compact form that only involves the scattering matrix and reservoir Green’s functions. We...journal article 2008
