Quantum Breathers in a Nonlinear Lattice
W. Z. Wang, J. Tinka Gammel, A. R. Bishop +1
We study nonlinear phonon excitations in a one-dimensional quantum nonlinear lattice model using numerical exact diagonalization. We find that multi-phonon bound states exist as ei…
Implications of Charge Ordering for Single-Particle Properties of High-Tc Superconductors
M. I. Salkola, V. J. Emery, S. A. Kivelson
The consequences of disordered charge stripes and antiphase spin domains for the properties of the high-temperature superconductors are studied. We focus on angle-resolved photoemi…
Impurity States and the Absence of Quasiparticle Localization in Disordered D-Wave Superconductors
A. V. Balatsky, M. I. Salkola
The absence of localization of impurity-induced low-energy quasiparticle states in a two-dimensional -wave superconductor is argued for any amount of disorder in the limit of un…
Impurity-Induced Virtual Bound States in d-Wave Superconductors
A. V. Balatsky, M. I. Salkola, A. Rosengren
It is shown that a single, strongly scattering impurity produces a bound or a virtual bound quasiparticle state inside the gap in a -wave superconductor. The explicit form of th…
