Summary: This study investigates electron transport through hybrid structures of graphene and SWCNTs (both metallic and semiconducting), finding that the interactions between SWCNT and SLG affect the electronic transport in hybrid nanostructures. The electronic structure and transport properties of hybrids change with increasing interaction, with semiconducting SWCNTs and metallic SWCNTs showing different behavior at low biases. This difference is attributed to changes in the electronic structure, local density of states, and energy dispersion for electrons due to the interaction between atoms of the two components.

Summary: The study investigated the modified electronic structure and single-carrier transport of individual hybrid core-shell metal-semiconductor Au-ZnS quantum dots using a scanning tunnelling microscope. The evolution of energy structure and charge transport from the metallic building block core to the core-shell metal-semiconductor QDs was revealed. The findings highlight the potential for fabricating tailored metal-semiconductor QDs for single-electron devices.

Summary: Invariant manifolds play a crucial role in organizing global dynamical behaviors, especially in multi-well systems where the transition between potential wells is governed by them. By solving proper boundary value problems, the study explores how invariant manifolds can be applied to both conservative and dissipative systems to study the transition dynamics between potential wells. The numerical results indicate that in conservative systems, the transition region forms a cylinder, while in dissipative systems, it forms an ellipsoid. The algorithms developed provide a robust theoretical-computational framework for studying escape and transition dynamics.

Summary: The study proposes a Gaussian quantum metrology scheme using bimodal quantized optical fields as the quantum probe, achieving precision close to the sub-Heisenberg limit in ideal conditions. However, Markovian decoherence leads to divergent metrological errors, which can be overcome by non-Markovian dynamics. This provides an efficient way to achieve high-precision quantum metrology in practical continuous-variable systems.

Summary: The study reveals that introducing different periodicities into a Josephson junction in a resistor environment can lead to competition between different phases, resulting in nonmonotonic temperature dependence of the differential resistance. This phenomenon is particularly significant at low temperatures and can be confirmed by fermionization and models such as helical wires.

Summary: Organic single benzene fluorescent molecules often suffer from aggregation-induced quenching effect. Cocrystal engineering can change the molecular arrangement and interactions, leading to enhanced emission properties. This study prepared two cocrystals and found that they weakened the pi-pi interactions, resulting in enhanced emission.

Summary: This paper compares the operating cost of a single-stack and a multi-stack fuel cell hybrid electric vehicle (FC-HEV), including hydrogen consumption and degradation of the fuel cell (FC). A hierarchical energy management strategy (EMS) is developed for the multi-stack system. Results show that the FC-HEV with a multi-stack structure has lower hydrogen and degradation costs compared to the single-stack structure.

Summary: This study demonstrates that the conductivity of hybrid vanadium bronzes can be controlled over six orders of magnitude through the choice of specific molecular components. By varying the steric profile, charge density, and propensity to hydrogen bond of eight diammonium-based molecules, different V-O connectivity motifs were introduced into the two-dimensional vanadium oxide layers. The relationship between vanadium oxide layer topology and electron localization was investigated using various techniques, revealing distinct electronic behavior depending on the molecular templation principles.

Summary: The study focuses on the vacuum Rabi splitting of a qubit ultrastrongly coupled to a cavity mode and a radiation reservoir, showing that the Lamb shift plays an essential role in modifying the coupling. As the cavity-qubit coupling increases, the emission spectrum undergoes changes with peaks narrowing and broadening until they have similar widths.

Summary: We propose a method for associative memory using a single driven-dissipative quantum oscillator, which utilizes its infinite degrees of freedom in phase space and improves the storage capacity of discrete neuron-based systems. By modifying the driving strength, the stored patterns of the system can be continuously tuned, providing a modified learning rule. The associative-memory capability is related to the spectral separation in the Liouvillian superoperator, resulting in a long timescale separation and a metastable phase.

Summary: The concept of quasi-phasematching (QPM) is developed in a Josephson traveling-wave parametric amplifier (JTWPA) with three-wave mixing (3WM), resulting in a relatively large and flat bandwidth with strong suppression of unwanted modes. This is achieved by periodically inverting groups of flux-biased radio frequency superconducting quantum interference devices (SQUIDs) in the JTWPA.

Summary: The recently proposed Josephson traveling-wave parametric amplifier (JTWPA) based on a ladder transmission line and utilizing three-wave mixing has the potential to achieve a gain of 20 dB and a flat bandwidth of at least 4 GHz. By using engineered dispersion loadings through periodic modulation of circuit parameters, unwanted higher tones can be efficiently suppressed while maintaining a reasonably small ripple (+/- 2 dB) in the gain-vs-frequency dependence. This allows for a wide 3 dB-bandwidth from 3 to 9 GHz.

Summary: This study investigates the impact of circuit parameter variation on the performance of Josephson traveling-wave parametric amplifiers (JTWPAs). It focuses on a specific configuration utilizing flux-biased nonhysteretic rf-SQUIDs in a transmission line, harnessing the three-wave mixing (3WM) regime. Two dispersion engineering concepts, resonant phase-matching (RPM) and periodic capacitance modulation (PCM), are discussed. The analysis demonstrates the importance of suitable circuit parameter sets and offers insights into making JTWPA circuits more robust to parameter variation.
