Summary: We propose a scheme to enhance the phonon blockade effect in a quadratically coupled optomechanical system by introducing a mechanical parametric amplifier (MPA) through a degenerate parametric drive. Both the single-phonon resonant regime and multipath interference regime can achieve phonon blockade due to the optomechanical nonlinearity and MPA. The combination of these two regimes enhances the phonon blockade effect compared to the regime without MPA. Moreover, our scheme shows that the two-time second-order correlation function gradually tends to one without rapid oscillations, suggesting that high time resolution is not necessary in the detection.

Summary: This study investigates the phenomenon of phonon blockade in a squeezed cavity optomechanical system. It explores the mechanical nonlinearity through analyzing the statistical properties of phonons and proposes a method to detect phonon blockade through measuring the correlation function of the squeezed cavity mode. The results suggest that strong single-phonon nonlinearity can be achieved by squeezing the cavity mode, enabling the realization of phonon blockade even with weak optomechanical interactions.

Summary: The discovery of high-performance materials is an active field in photovoltaics research. This study proposes a computationally efficient method to screen potential thin-film PV absorbers by accounting for phonon-assisted absorption across the indirect band gap. Through screening descriptors, 28 candidate materials, including 20 indirect band gap semiconductors, were identified.

Summary: This study provides a comprehensive analysis of the phonon properties of transition metal dichalcogenides (TMDs) MoS2 and MoTe2, examining the effects of temperature, laser excitations, polarization, and flake thickness on phonon characteristics. The anharmonicity variations are explained in terms of phonon symmetries, electron-phonon coupling, and phonon-phonon interactions. Furthermore, the impact of the underlying substrate on the anharmonic properties of in-plane and out-of-plane phonons is estimated, elucidating the intrinsic phonon properties of two-dimensional layered materials.

Summary: The article discusses the phenomenon of Andreev blockade, where electrons cannot form Cooper pairs and are blocked on a double quantum dot when the drain lead is a spin-singlet superconductor due to suppressed Andreev reflections. It is noted that Andreev blockade occurs for any occupation of the dot adjacent to the superconductor, unlike the well-studied Pauli blockade which requires odd occupations.

Summary: A novel low temperature annealing method using ultra-short laser pulses for selective crystallization of gold thin films is proposed. The study shows that applying 515 nm laser improves electrical conductivity of 18-nm gold films by up to 40%. The results suggest that non-equilibrium energy transfer between electrons and lattice leads to a melt-free crystallization process.

Summary: The study systematically investigated the arrangement of hydroxyl groups on graphene sheets and found that hydroxyl groups tend to gather at Para-positions to form perfect ring-like hexahydroxyl group adsorption. The orientation of hydrogen atoms in hydroxyl groups and the impact of the number of hydroxyl groups on binding energy were also studied. The research results contribute to a deeper understanding of the structure and properties of graphene oxide.

Summary: A scheme of nonreciprocal conventional phonon blockade is proposed in a spinning optomechanical resonator coupled with a two-level atom. The scheme allows for achieving phonon blockade and phonon-induced tunneling by adjusting the mechanical drive field. The effects are robust to optical noise and feasible in low-Q cavity.

Summary: In a hybrid micromaser system, the generation of vacuum phonon trapping states and the trapping of phonons and photons at the same interaction times are demonstrated. Increasing the cavity-oscillator coupling can generate coherent phonon states. Phonon blockade effect can be engineered by connecting the system to a squeezed phonon reservoir.

Summary: The team studied multimagnon blockade and magnon-induced tunneling in a hybrid ferromagnet-superconductor system, achieving single magnon blockade, multimagnon blockade including two- and three-magnon blockades, and magnon-induced tunneling by controlling parameters. Switching from magnon blockade to magnon-induced tunneling was achieved by controlling the overall phase of the loop transition, and single-magnon blockade could be transformed into a multimagnon blockade via phase modulation. The scheme presented offers an alternative method for manipulating few-magnon states with potential applications in quantum communication and quantum information processing.

Summary: Room-temperature-processed amorphous InGaZnO thin-film transistors with Ge gate electrodes show higher carrier mobility, which is attributed to the stronger coupling between the higher-energy plasmons of the Ge gate electrode and the phonons of the gate dielectric, leading to weaker gate-dielectric vibration.

Summary: A sensitive non-enzymatic electrochemical glucose sensor was developed using a two-step method with surfactant-assisted and electrochemical deposition. The modified electrode showed a larger active surface area and faster electron transfer efficiency, resulting in higher electrocatalytic activity for glucose sensing. The sensor demonstrated high sensitivity, low detection limit, wide linear range, and selectivity towards glucose in the presence of interfering species, making it suitable for further applications.

Summary: Molecular crystals are a flexible platform for inducing novel electronic phases. By growing KxC60 fullerides on hexagonal layered Bi2Se3, a Mott transition from a molecular insulator to a correlated metal occurs upon doping, resulting in the evolution of an in-gap state into highly dispersive Dirac-like fermions and the emergence of superconductivity. This challenges the commonly accepted description of low-energy quasiparticles and suggests a parallel with cuprate superconductors, indicating the potential of molecular crystals in engineering electron-electron interactions.

Summary: Irradiating normal-superconducting junctions with microwave photons leads to significant effects, with dissipation being a more sensitive probe of microwave photons than the supercurrent. Enhancements in dissipation at phase zero under high frequency photons are attributed to Andreev level transitions, indicating the potential for improving superconducting photodetectors and investigating photoassisted physics in hybrid superconducting systems.
