Role of the kinematics of probing electrons in electron energy-loss spectroscopy of solid surfaces
V. U. Nazarov, V. M. Silkin, E. E. Krasovskii
Inelastic scattering of electrons incident on a solid surface is determined by the two properties: (i) electronic response of the target system and (ii) the detailed quantum-mechan…
Gate-tunable conducting oxide metasurfaces
Yao-Wei Huang, Ho Wai Howard Lee, Ruzan Sokhoyan +5
Metasurfaces composed of planar arrays of sub-wavelength artificial structures show promise for extraordinary light manipulation; they have yielded novel ultrathin optical componen…
Theoretical Studies of Graphene Nanoribbon Quantum Dot Qubits
Chih-Chieh Chen, Yia-Chung Chang
Graphene nanoribbon quantum dot qubits have been proposed as promising candidates for quantum computing applications to overcome the spin-decoherence problems associated with typic…
Engineering the interlayer exchange coupling in magnetic trilayers
Ching-Hao Chang, Kun-Peng Dou, Ying-Chin Chen +2
When the thickness of metal film approaches the nanoscale, itinerant carriers resonate between its boundaries and form quantum well states (QWSs), which are crucial to account for…
Coboson many-body formalism for cold atom dimers with attraction between different fermion species only
Monique Combescot, Shiue-Yuan Shiau, Yia-Chung Chang
Unlike the Coulomb potential that acts between all semiconductor carriers, the potential commonly used for BCS superconductors and cold atom gases acts between different fermion sp…
A Mixed Basis Density Functional Approach for One-Dimensional Systems with B-splines
Chung-Yuan Ren, Yia-Chung Chang, Chen-Shiung Hsue
A mixed basis approach based on density functional theory is extended to one-dimensional(1D) systems. The basis functions here are taken to be the localized B-splines for the two f…
Toroidal optical activity
T. A. Raybould, V. A. Fedotov, N. Papasimakis +5
Optical activity is ubiquitous across natural and artificial media and is conventionally understood in terms of scattering from electric and magnetic moments. Here we demonstrate e…
Correlation Energy for Elementary Bosons: Physics of the Singularity
Shiue-Yuan Shiau, Monique Combescot, Yia-Chung Chang
We propose a compact perturbative approach that reveals the physical origin of the singularity occurring in the density dependence of correlation energy: like fermions, elementary…
Derivative discontinuity with localized Hartree-Fock potential
V. U. Nazarov, G. Vignale
The localized Hartree-Fock potential has proven to be a computationally efficient alternative to the optimized effective potential, preserving the numerical accuracy of the latter…
Quantum interference and structure-dependent orbital-filling effects on the thermoelectric properties of quantum dot molecules
Chih-Chieh Chen, David M T Kuo, Yia Chung Chang
The quantum interference and orbital filling effects on the thermoelectric (TE) properties of quantum dot molecules with high figure of merit are illustrated via the full solution…
Electronic excitations in quasi-2D crystals: What theoretical quantities are relevant to experiment?
Vladimir U. Nazarov
The ab initio theory of electronic excitations in atomically thin [quasi-two-dimensional (Q2D)] crystals presents extra challenges in comparison to both the bulk and purely 2D case…
Negative static permittivity and violation of Kramers-Kronig relations in quasi-two-dimensional crystals
Vladimir U. Nazarov
We investigate the wave-vector and frequency-dependent screening of the electric field in atomically thin (quasi-two-dimensional) crystals. For graphene and hexagonal boron nitride…
Quantum interference and electron correlation in charge transport through triangular quantum dot molecules
Chih-Chieh Chen, Yia-chung Chang, David M T Kuo
We study the charge transport properties of triangular quantum dot molecule (TQDM) connected to metallic electrodes, taking into account all correlation functions and relevant char…
