Quantum lattice dynamical effects on the single-particle excitations in 1D Mott and Peierls insulators
H. Fehske, G. Wellein, G. Hager +2
As a generic model describing quasi-one-dimensional Mott and Peierls insulators, we investigate the Holstein-Hubbard model for half-filled bands using numerical techniques. Combini…
Electron transmission through a short interacting wire: 0.7 conductance anomaly
D. Schmeltzer, A. Saxena, A. R. Bishop +1
We investigate tunneling through a short interacting wire. We identify two temperature regimes (a) ( is the length of the short wire) an…
Structurally specific thermal fluctuations identify functional sites for DNA transcription
G. Kalosakas, K. Ø. Rasmussen, A. R. Bishop +2
We report results showing that thermally-induced openings of double stranded DNA coincide with the location of functionally relevant sites for transcription. Investigating both vir…
Electronic properties of structural twin and antiphase boundaries in materials with strong electron-lattice couplings
K. H. Ahn, T. Lookman, A. Saxena +1
Using a symmetry-based atomic scale theory of lattice distortions, we demonstrate that elastic textures, such as twin and antiphase boundaries, can generate intricate electronic in…
Atomic scale elastic textures coupled to electrons in superconductors
K. H. Ahn, Jian-Xin Zhu, Z. Nussinov +4
We present an atomic scale theory of lattice distortions using strain related variables and their constraint equations. Our approach connects constrained atomic length scale variat…
Competing interactions of spin and lattice in the Kondo lattice model
M. Gulacsi, A. Bussmann-Holder, A. R. Bishop
The magnetic properties of a system of coexisting localized spins and conduction electrons are investigated within an extended version of the one dimensional Kondo lattice model in…
