Vacuum-field-induced state mixing
SciPost Physics, 2023 By engineering the electromagnetic vacuum field, the induced Casimir-Polder shift (also known as Lamb shift) and spontaneous emission rates of individual atomic levels can be controlled. When the strength of these effects becomes comparable to the energy

Impact of Nd Doping on Electronic, Optical, and Magnetic Properties of ZnO: A GGA + U Study
Molecules, 2023 The electronic, optical, and magnetic properties of Nd-doped ZnO systems were calculated using the DFT/GGA + U method. According to the results, the Nd dopant causes lattice parameter expansion, negative formation energy, and bandgap narrowing, resulting

Anomalous discrete flavor symmetry and domain wall problem
Physics Letters B, 2019 Discrete flavor symmetry is often introduced for explaining quark/lepton masses and mixings. However, its spontaneous breaking leads to the appearance of domain walls, which is problematic for cosmology. We consider a possibility that the discrete flavor

SciPost Physics, 2021 We investigate the two-dimensional motion of relativistic cold electrons in the presence of ‘strictly’ spatially varying magnetic fields satisfying, however, no magnetic monopole condition.

Degeneracy of light scattering and absorption by a single nanowire
Scientific Reports, 2021 We theoretically and numerically prove that under an electromagnetic plane wave with linear polarization incident normally to a single nanowire, there exists a power diagram that could indicate scattering properties for any system configurations ...

Theory of noninteracting fermions and bosons in the canonical ensemble
Physical Review Research, 2020 We present a self-contained theory for the exact calculation of particle number counting statistics of noninteracting indistinguishable particles in the canonical ensemble.

Tetraquark operators in lattice QCD and exotic flavour states in the charm sector
Journal of High Energy Physics, 2017 We present a general class of operators resembling compact tetraquarks which have a range of colour-flavour-spin structures, transform irreducibly under the symmetries of the lattice and respect other relevant symmetries.

Appearance of branched motifs in the spectra of BCN type Polychronakos spin chains
Nuclear Physics B, 2020 As is well known, energy levels appearing in the highly degenerate spectra of the AN−1 type of Haldane-Shastry and Polychronakos spin chains can be classified through the motifs, which are characterized by some sequences of the binary digits like ‘0’ and
