Band Structure and Intersubband Transitions of Three-Layer Semiconductor Nanoplatelets
Nanomaterials, 2020 This paper presents the first general theory of electronic band structure and intersubband transitions in three-layer semiconductor nanoplatelets. We find a dispersion relation and wave functions of the confined electrons and use them to analyze the band

Decoherence in nanostructures and quantum systems [PDF]
Physica E: Low-dimensional Systems and Nanostructures, 2003 Decoherence phenomena are pervasive in the arena of nanostructures but perhaps even more so in the study of the fundamentals of quantum mechanics and quantum computation. Since there has been little overlap between the studies in both arenas, this is an attempt to bridge the gap.

Radiative coupling of two quantum emitters in arbitrary metallic nanostructures
Scientific Reports, 2022 We propose a general formalism beyond Weisskopf–Wigner approximation to efficiently calculate the coupling matrix element, evolution spectrum and population evolution of two quantum emitters in arbitrary metallic nanostructures.

Pseudospin Quantum Computation in Semiconductor Nanostructures [PDF]
Physical Review Letters, 2003 We theoretically show that spontaneously interlayer-coherent bilayer quantum Hall droplets should allow robust and fault-tolerant pseudospin quantum computation in semiconductor nanostructures with voltage-tuned external gates providing qubit control and a quantum Ising Hamiltonian providing qubit entanglement.

Quantum phenomena in nanostructures
Journal of Physics: Conference Series, 2021 Abstract Quantum phenomena in nanostructures, especially epitaxial structures, are utilized for the fabrication of quantum devices. Here we discuss self organized growth of epitaxial quantum structures on silicon and their electronic structures, such as electronic density of states, and electronic transport in such systems.
