Summary: This paper reports the stabilization of ultrathin out-of-plane ferroelectricity in oxide heterostructures through the design of an artificial flux-closure architecture. By inserting an in-plane-polarized ferroelectric epitaxial buffer, the continuity of polarization at the interface is maintained, resulting in the emergence of polarization in ultrathin ferroelectric films.

Summary: This work investigates the reversible and irreversible effects in a horizon plane under a z-axis alternating current field by studying atomically thin films. The simulation results reveal the driving forces and transformations in domain structures and phase states, providing a reasonable understanding of the alternating current field effect.

Summary: Under the influence of a magnetic field, two weakly linked superconducting ultrathin films exhibit different superconducting states, with one characterized by staggered supercurrent loops and a superfluid density wave, and the other by uniform superfluid density. The phase transition between these two states falls within a specific universality class.

Summary: A new error mitigation technique for quantum devices is introduced in this work, which is based on the assumption that noise in a deep quantum circuit is well described by global depolarizing error channels. This technique has been shown to effectively improve quantitative results in quantum many-body physics, allowing for extraction of previously inaccessible information such as meson masses.

Summary: An optical-thermal method combining UV illumination and oxygen annealing is introduced to achieve tunability in the threshold voltage (V-T) of ultrathin In2O3. This method allows for both positive and negative V-T tuning and is reversible. The controllability of V-T enables the realization of depletion-load inverters, multi-state logic devices, and wafer-scale V-T modulation, demonstrating its potential for low-power circuit design and non-von Neumann computing applications.

Summary: The physics of electrons, photons, and their plasmonic interactions change significantly when one or more dimensions are reduced to atomic-level thicknesses. This study proposes a new method of making ultrathin metal films that exhibit excellent plasmonic properties similar to bulk films, which is demonstrated by directly observing plasmons in the film.

Summary: This review examines the state of the art measurement techniques for the Dzyaloshinskii-Moriya interaction constant (DMI constant D), particularly in systems where the DMI arises from the interface between two materials. The review provides an overview of experimental techniques, theoretical background, and models for quantifying the DMI constant. The measurement techniques are categorized into three types: domain-wall-based measurements, spin-wave-based measurements, and spin-orbit torque-based measurements. The advantages and disadvantages of each method are analyzed, and the D values at different interfaces are compared. The review aims to improve understanding of the applicability of different techniques and explain discrepancies in literature values.

Summary: This article discusses the effect of GABA on neuronal excitability, the complex spatiotemporal interaction between GABAergic and glutamatergic inputs, and mechanisms influencing [Cl-](i) beyond Cl- transporters expression. Research suggests that during early developmental stages, GABA can act as an inhibitory neurotransmitter.

Summary: A novel depolarizing chipless tag configuration with high angular insensitivity is proposed in this paper. It comprises two dipole resonators arranged with a relative rotation of 45 degrees to improve depolarization properties. The tag is designed to have 4 angular independent frequency peaks and demonstrate peculiar frequency shifts achieved when the electric fields rotate in the plane of the dipole.

Summary: This study characterized the electronic transport and optical properties of NbTiN/AlN multilayers with ultrathin NbTiN layers, confirming their unique hyperbolic metamaterial properties. It was found that enhancing electron-electron interaction in superconductors can increase the superconductive transition temperature, T-c. Additionally, the metamaterial engineering approach was shown to be effective in enhancing critical fields in the superconducting hyperbolic metamaterials.

Summary: The study presents a method to mitigate noise in quantum computers by estimating and correcting the depolarizing noise rate, experimentally validated on a simulation of the Heisenberg model. The approach, combined with readout-error correction, randomized compiling, and zero-noise extrapolation, produces close to exact results even for circuits containing hundreds of CNOT gates, with analytical improvement shown when zero-noise extrapolation is applied to the output of the method.

Summary: Through experiments, we show that spontaneous polarization remains in a ferroelectric/dielectric bilayer thin film, even with a thick dielectric layer, suggesting no practical thickness limit. We also demonstrate that the spontaneous polarization persists even when the thickness of the ferroelectric layer approaches zero, hinting at the absence of a critical thickness. Additionally, interfacial effects limit multidomain formation and govern polarization switching mechanisms.

Summary: Using electrodynamical description, an expression for the electric-field intensity enhancement (FIE) due to epsilon-near-zero (ENZ) polariton modes is presented. The study shows that FIE reaches a limit in ultrathin ENZ films, inversely proportional to ENZ losses. The research also predicts high values of FIE in ultrathin polar semiconductor films.
