We propose to use 4-level systems with an additional symmetry to encode pairs of coupled qubits. The chosen symmetry allows clusters to perform universal quantum computation on their encoded qubits, and gives full control over their energy spectrum. Each level can be dynamically decoupled from its immediate environment, modelled by its tunneling-coupling to a semi-infinite lead, turning the...
We are exploring solid state precipitation methods to grow high-quality Ge-Sn nanoparticles with controlled compositions and band gaps. There have been decades of research to produce semiconductor nanoparticles using wet chemistry synthetic techniques, however many of these approaches are not compatible with current CMOS device manufacturing. Si-Ge-Sn alloys offer great new material...
Numerous advances have been made in the field of Si photonics, attractive in terms of cost, power consumption and performance in comparison to conventional technologies. Photodetectors which converts light to electrical signals are vital parts of Si photonics system. Advances in materials science have led to photodetectors that operate in the short infrared wavelength range (1.3 - 2.5µm). This...
Phytoglycogen occurs naturally in the form of compact, 42 nm diameter glucose-based nanoparticles in the kernels of sweet corn. Its highly branched, dendritic structure leads to interesting and useful properties that make the particles ideal as unique additives in personal care, nutrition and biomedical formulations. The properties of phytoglycogen nanoparticles can be altered through chemical...
The problem of stretching flexible polymers was covered in a seminal paper by John F. Marko and Eric D. Sigga in 1995, where they used the wormlike chain model to calculate the force required to stretch long segments of DNA. Their approach used a ground state dominance method to solve the modified diffusion equation, applicable to long (flexible) chains only. Here, using the same Green’s...
It was recently demonstrated that the layered van der Waals bonded material MnBi$_2$Te$_4$ is an intrinsic antiferromagnetic topological insulator. The opening of an electronic gap in the surface state, originating in the presence of exchange interaction, was experimentally verified by ARPES. However, the presence and magnitude of this gap are still under debate. To develop a comprehensive...
We model a number of both closed-packed and non-closed-packed crystals inside a cholesteric liquid crystal (LC) with different pitch values and nematic LC through the Landau–de Gennes free-energy method[1]. We investigated the anisotropic interactions between particles with heterogeneous boundary conditions inside both nematic and cholesteric liquid crystals[2]. The results show that it is...
