Distortion of the local density of states in a plasmonic cavity by a quantum emitter
New Journal of Physics, 2021 We investigate how the local density of states in a plasmonic cavity changes due to the presence of a distorting quantum emitter. To this end, we use first-order scattering theory involving electromagnetic Green’s function tensors for the bare cavity ...

Density of States of Colloidal Glasses [PDF]
Physical Review Letters, 2010 Glasses are structurally liquid-like, but mechanically solid-like. Most attempts to understand glasses start from liquid state theory. Here we take the opposite point of view, and use concepts from solid state physics. We determine the vibrational modes of a colloidal glass experimentally, and find soft low-frequency modes that are very different in ...

New Canonical and Grand Canonical Density of States Techniques for Finite Density Lattice QCD
Particles, 2020 We discuss two new density of states approaches for finite density lattice QCD (Quantum Chromo Dynamics). The paper extends a recent presentation of the new techniques based on Wilson fermions, while here, we now discuss and test the case of finite ...

Modelling of density of states and energy level of chalcogenide quantum dots
, 2021 Quantum dots (QDs) or semiconductor nanocrystals are luminous materials with unique optical properties that can be fine-tuned by varying the size of the material.

Density of states within the bandgap of perovskite thin films studied using the moving grating technique [PDF]
, 2022 In this work, we further study the moving grating technique applied to halide perovskite thin-film materials. First, we show some problems that emerge when analyzing the experimental data with the classical formulation, which does not distinguish between

First–Principles Calculations of Band Offsets in GaAs/AlAs System [PDF]
Progress in Physics of Applied Materials, 2022 The lattice-matched system (GaAs)n/(AlAs)n superlattice is calculated for two different values of n=3 and 6 within ab initio pseudopotential density-functional theory using Quantum Espresso package of program exploiting the ultra-soft atomic ...

Electron spectra in double quantum wells of different shapes
New Journal of Physics, 2022 We suggest a method for calculating electronic spectra in ordered and disordered semiconductor structures (superlattices) forming double quantum wells (QWs).

Liquid-infiltrated photonic crystals: Ohmic dissipation and broadening of modes [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 The pronounced light–matter interactions in photonic crystals make them interesting as opto–fludic “building blocks” for lab–on–a–chip applications.

Proceedings of 34th annual International Symposium on Lattice Field Theory — PoS(LATTICE2016), 2017 Although Monte Carlo calculations using Importance Sampling have matured into the most widely employed method for determining first principle results in QCD, they spectacularly fail for theories with a sign problem or for which certain rare configurations play an important role.
