Molecular electronics is a promising candidate to meet the increasing demands of electronic component miniaturization. Within this field, interaction between molecular functional center and its environment plays profound role both in designing devices understanding structure-property relationships at molecular/atomic level. Herein, motivated by an isomer nickel tetraphenylporphyrin (Ni-TPP) molecule, we study dynamical thermodynamical properties such structure, with aid side-coupled...
Recently, the Anderson disorder-induced topological amorphous insulator has been proposed in a two-dimensional lattice. However, interplay between disorder and higher-order band topology remains unclear. In this work, we investigate effects of on phase. We demonstrate that phase exhibits robustness against weak but is destroyed by strong disorder. addition, transition from topologically trivial to phase, dubbed insulator, characterized quantized quadrupole moment existence corner states.

An investigation to significantly enhance coupling nitrogen−vacancy (NV) centers at a single-quanta level is of great interest further explore its applications in quantum information processing (QIP). This study explores joint scheme NV–phonon coherent with two methods working together hybrid optomechanical systems. Both are mechanics-induced mode field (MFC) that lead, respectively, the modification spatial distribution optical and mechanical parametric amplification (MPA) realized by...
Long-distance superexchange coupling provides a powerful tool for scalable quantum processors required in information and computation. Quadripartite spin-crossover molecules are prototypical systems studying novel phenomena assisted by interactions. In this paper, we consider quadripartite molecule where two central monomers connected to electrodes, whereas another side coupled their neighboring monomers. Numerical renormalization group results demonstrate that, when the energy level spacing...
Semiconductor quantum dots in close proximity to superconductors may provoke localized bound states within the superconducting energy gap known as Yu-Shiba-Rusinov state, which is a promising candidate for constructing Majorana zero modes and topological qubits. Side-coupled double dot systems are ideal platforms revealing secondary effect. Numerical renormalization group calculations show that if central can be treated noninteracting resonant level, it acts medium due ordinary The state...
Recently, the structural disorder-induced topological phase transitions in periodic systems have attracted much attention. However, aperiodic such as quasicrystalline systems, interplay between disorder and band topology is still unclear. In this work, we investigate effects of on a quantum spin Hall insulator higher-order two-dimensional Amman-Beenker tiling lattice, respectively. We demonstrate that can induce transition from normal to an amorphous phase, which confirmed by bulk gap...

Semiconductor quantum dots are considered to be promising candidates for the hardware of information technology and optoelectronic devices. Herein, motivated by a tetrahedrally shaped colloidal quadruple dot structure made from In-based III--V semiconductors, which has been synthesized very recently Leemans et al. [J. Am. Chem. Soc., 143, 4290 (2021)], we provide timely insight into electronic transport phase transition (QPT) such an architecture. When interdot hopping between different side...
Abstract Magnetic impurities connected to superconductors reservoir result in bound states within the superconducting gap, so called Yu–Shiba–Rusinov (YSR) state. In past few years, this field has gained much attention since it is crucial for engineering novel many-body states, with perspective of manufacturing Majorana Fermions. The underlying physical picture YSR state depends closely on form leads, manner which are organized, and also diverse local interactions, always disclosed aid...

We consider a magnetic molecular trimer sandwiched between two metal electrodes, and study the effect of anisotropy on charge transport properties, Kondo effect, temperature inter-monomer hopping robustness.
We implement the Landau–Zener surface hopping (LZSH) method to study nonadiabatic dynamics of some typical one-dimensional (1D) models, including well-tested Tully's models. For models like original linear avoided crossing model used derive LZ formula, LZSH can provide very accurate results compared with full quantum calculations and fewest-switches (FSSH) simulations. single model, only present us semi-quantitative results. And for dual fails capture interference effect. Furthermore, shows...
Hybrid quantum dot structures are potential building blocks for spintronic devices and logic gates, within which the understanding of many-body correlations is a prerequisite implementing information processing generating controlled entanglement. Herein, we consider hybrid tripartite device, one embedded directly between source drain electrodes, while other two dots side coupled to first one. Modeling system using three-impurity Anderson model, concentrate on Ruderman-Kittel-Kasuya-Yosida...
