Summary: Understanding the thermodynamics of driven quantum systems strongly coupled to thermal baths is a central focus of quantum thermodynamics and mesoscopic physics. A variety of different methodological approaches exist in the literature, all with their own advantages and disadvantages. In this work, the authors generalize the mesoscopic leads approach to incorporate an arbitrary time dependence in the system Hamiltonian.

Summary: This study investigates the steady-state direct current transport characteristics of a system composed of an interacting quantum dot coupled to two metallic noninteracting leads with Rashba spin-orbit coupling. The authors employ an interpolative perturbative approach to obtain the single-particle spectra, current, and differential conductance over a wide range of spin-orbit coupling and bias values. The results provide qualitative explanations for recent experimental observations and reproduce the temperature dependence of the zero-bias conductance.

Summary: In this study, it was demonstrated that a new composite material can be formed by adding copper and doping material to a specific composition of copper germanium antimony tellurides. The composite material exhibits superior thermoelectric properties suitable for temperature-dependent applications. Furthermore, strategies such as optimizing grain boundaries and temperature-induced microstructure reset were proposed to overcome material degradation during electrical current application.

Summary: This paper introduces and analyzes the concept of manipulating optical chirality by strongly coupling the optical modes of chiral nanostructures with excitonic transitions in molecular layers or semiconductors. By demonstrating the generation of two spectral branches that retain the object's high chirality density through strong coupling with a nearby excitonic material, the authors propose that post-fabrication manipulation of optical chirality can be achieved. These findings are further verified through simulations of circular dichroism in a realistic chiral architecture.

Summary: This article proposes using the high local curvatures at the tips of plasmonic nanocubes to achieve strong coupling at visible frequencies. It highlights a trade-off between coupling strength and emission yield in gold nanocube dimers, while silver nanocube dimers exhibit similar coupling strength but higher emission yield, providing design rules for efficient strongly coupled hybrid nanostructures at room temperature.

Summary: This paper presents a quasi-planar chiral metamaterial made of metal-insulator-metal (MIM) tetramer arrays that support multiple plasmon modes and achieve significant chiroptical responses. The chiroptical responses can be controlled by adjusting the insulator thickness, switching between near-field and far-field coupling regimes. Numerical calculations reveal that near-field coupling dominates at small insulator thickness, while far-field coupling becomes dominant at large spacing due to phase retardation. The tunable plasmonic chirality of the quasi-planar chiral metamaterial enables efficient light modulation for polarization conversion from circular to elliptical/linear polarization.

Summary: This study demonstrated highly efficient hole transfer from photoanodes to oxygen evolution catalysts by coupling NiCo catalyst with carbon quantum dots on alpha-Fe2O3 photoanodes, achieving one of the highest PEC activities and H2 generation rates. The carbon quantum dots acted as an efficient medium to promote hole transport and selectively tailor the electronic structure of surface-active sites, significantly enhancing surface charge separation and oxygen evolution process.

Summary: Researchers reported the rational design and optimized synthesis of 2D covalent organic frameworks (2D-COFs) for the generation of MoS2/2D-COF vdWHs with strong interlayer coupling effects. The high crystallinity of 2D-COF films enables the engineering of an ultrastable periodic doping effect on MoS2, leading to enhanced field-effect mobility in devices.

Summary: Scaling of the behavior of a nanodevice involves a unique and smooth function of a scaling parameter, with the Dukhin number serving as an appropriate parameter for certain limits. The non-linear dependence of selectivities on system parameters necessitates the use of alternative scaling parameters in different limits of nanopore length.

Summary: We have created a holographic superfluid that exhibits different behaviors depending on the positive or negative gauge-axion coupling, such as metallic or insulating behavior in the normal state. The system also displays a mid-IR peak in the AC conductivity due to the competition between explicit and spontaneous symmetry breaking, leading to the presence of a pseudo-Goldstone mode. Additionally, the AC conductivity shows a dip at low frequencies, resulting from the excitation of the spontaneous symmetry breaking Goldstone mode.

Summary: Colloidal assembly into chiral superstructures can be achieved rapidly and with materials of any chemical compositions and sizes using magnetic assembly techniques. The chiral superstructures are controlled by the strength of the magnetic field and the orientation of the magnets. Moreover, the chirality can be transferred to achiral molecules by incorporating guest molecules into the magnetic nanostructures.

Summary: Artificial biomimetic chloride anionophores have potential applications in anticancer scaffolds. Stimuli-responsive chloride transporters that can be selectively activated inside cancer cells are rare. Light-responsive systems, with their spatiotemporal controllability, low toxicity, and high tunability, show promise for photodynamic therapy. In this work, o-nitrobenzyl-linked, benzimidazole-based protransporters and active transporters were studied, and one compound showed efficient ion transport activity. Detailed mechanistic studies revealed the main ion transport process and the necessity of double protection with photocages for complete activation by external light. The activated procarriers induced phototoxic cell death in MCF-7 cancer cells.

Summary: This study reveals novel and robust quantum transport regimes achievable in nanosystems by exploiting long-range hopping. In a 1D disordered nanostructure, transport efficiency experiences a disorder-enhanced transport (DET) regime, eventually reaching a disorder-independent transport (DIT) regime.

Summary: Cooperative emission of coherent radiation, known as superradiance, has been observed in CsPbBr3 nanocrystal superlattices. However, the presence of energetic disorder strongly suppresses superradiance. By analyzing superlattices of different dimensionalities and nanocrystal aspect ratios, it is predicted that superlattices composed of cuboid-shaped nanocrystals in three-dimensional (3D) space can enhance robustness against energetic disorder by up to 15-fold. Two-dimensional (2D) superlattices with small numbers of nanocrystals (N ≤ 103) are found to be up to 10 times more robust to static disorder and up to twice as robust to thermal decoherence compared to 3D superlattices with the same N. As N increases, a crossover in the robustness of superradiance from 2D to 3D superlattices occurs, with 3D superlattices showing cooperative robustness to disorder for large N (> 103). This suggests the possibility of observing room temperature superradiance in large 3D superlattices if nanocrystal size fluctuations can be minimized.

Summary: By using multi-photon entangled input states and photon-counting detection, this study estimates the phase uncertainty in a noiseless Mach-Zehnder interferometer. Bayesian inference is used to construct posterior uncertainty, and the optimal input states are obtained by minimizing the posterior variance. The study expands to a sequence of repeated measurements and develops optimal analytical formulae and scaling formula, which show the average number of shots required to reduce phase uncertainty to a target level. A comparison with a Monte Carlo simulation using frequentist inference suggests that the local non-adaptive method is the most effective practical method to reduce phase uncertainty.
