Local density of states in disordered graphene

, 2008
We study two lattice models, the honeycomb lattice (HCL) and a special square lattice (SQL), both reducing to the Dirac equation in the continuum limit. In the presence of disorder (gaussian potential disorder and random vector potential), we investigate

Loschmidt Echo and the Local Density of States [PDF]

, 2009
Loschmidt echo (LE) is a measure of reversibility and sensitivity to perturbations of quantum evolutions. For weak perturbations its decay rate is given by the width of the local density of states (LDOS).

Defect Properties and Band Energetics of Atomic Layer Deposited MoOX on Crystalline Si

Advanced Materials Interfaces
Molybdenum oxide (MoOx) thin films have been extensively investigated for selective hole extraction in solar cells, including as an efficient alternative to the well‐studied p‐type a‐Si:H layers in Si heterojunction cells.

Quasiparticle scattering and local density of states in the d-density wave phase [PDF]

, 2003
We study the effects of single-impurity scattering on the local density of states in the high-$T_c$ cuprates. We compare the quasiparticle interference patterns in three different ordered states: d-wave superconductor (DSC), d-density wave (DDW), and ...

Polaron density of states of AlAs/GaAs/AlAs and PbS/PbTe/PbS type quantum well

Condensed Matter Physics, 2007
Polaron energy spectrum of AlAs/GaAs/AlAs and PbS/PbTe/PbS quasi two-dimensional heterostructure as a function of the wave-vector is investigated based on the adiabatic approximation and the Ritz variational technique.

Phosphorylation state of postsynaptic density proteins [PDF]

Journal of Neurochemistry, 2005
AbstractThe postsynaptic density (PSD) is an electron‐dense structure located at the synaptic contacts between neurons. Its considerable complexity includes cytoskeletal and scaffold proteins, receptors, ion channels and signaling molecules, in line with the role of PSDs in signal transduction and processing.

Quasiparticle density of states in dirty high-T_c superconductors

, 1998
We study the density of quasiparticle states of dirty d-wave superconductors. We show the existence of singular corrections to the density of states due to quantum interference effects.

Interplay of disorder and magnetic field in the superconducting vortex state

, 2003
We calculate the density of states of an inhomogeneous superconductor in a magnetic field where the positions of vortices are distributed completely at random. We consider both the cases of s-wave and d-wave pairing.
