We study the interplay between strong electron-electron and electron-phonon interactions within a two-orbital molecule coupled to metallic leads, taking into account Holstein-like coupling of a local phonon mode to the molecular charge as well as phonon-mediated interorbital tunneling. By combining canonical transformations with numerical renormalization-group calculations to address the interactions nonperturbatively and on equal footing, we obtain a comprehensive description of the system’s…

Effects of Temperature and Hydrogen-Like Impurity on the Vibrational Frequency of the Polaron in RbCl Parabolic Quantum Dots

The properties of an electron strongly coupled to longitudinal optical (LO) phonon in RbCl parabolic quantum dot (PQD) with a hydrogen-like impurity at the center were investigated at a finite

Quantum transport through a deformable molecular transistor

The linear transport properties of a model molecular transistor with electron-electron and electron-phonon interactions were investigated analytically and numerically. The model takes into account

Kondo effect and channel mixing in oscillating molecules

We investigate the electronic transport through a molecule in the Kondo regime. The tunneling between the electrode and the molecule is asymmetrically modulated by the oscillations of the molecule,

Phonon-assisted tunneling and two-channel Kondo physics in molecular junctions

The interplay between vibrational modes and Kondo physics is a fundamental aspect of transport properties of correlated molecular conductors. We present theoretical results for a single molecule in

Phonon-assisted tunneling regimes in diatomic molecules

Electronic transport in diatomic molecules (two-level systems) connected to metallic contacts is analyzed in the presence of competing electron-electron and electron-phonon interactions. We show that

Numerical renormalization-group study of the symmetric Anderson-Holstein model : Phonon and electron spectral functions

We study the symmetric Anderson-Holstein (AH) model at zero temperature with Wilson's numerical renormalization-group (NRG) technique to investigate the interplay between the electron-electron and

Many-body effects on the transport properties of single-molecule devices.

The conductance through a molecular device including electron-electron and electron-phonon interactions is calculated using the numerical renormalization group method using the standard Kondo model with renormalized parameters.

Using scanning tunneling spectroscopy, this work is able to depict a molecular scale picture of how electrons interact with the vibrational degrees of freedom of single molecules in different transport regimes, which helps in the development of stable molecular devices, which may also carry a switchable functionality.

Kondo effect in a single-electron transistor

How localized electrons interact with delocalized electrons is a central question to many problems in sold-state physics. The simplest manifestation of this situation is the Kondo effect, which

Ab initio analysis of electron-phonon coupling in molecular devices.

A first principles analysis of electron-phonon coupling in molecular devices under external bias voltage and during current flow is reported and it is found that the low-lying modes are most important.
