Higher-order epitaxy: A pathway to suppressing structural instability and emergent superconductivity
Molecular beam epitaxy enables the growth of thin film materials with novel properties and functionalities. Typically, the lattice constants of films and substrates are designed to match to minimise disorders and strains. However, significant lattice mismatches can result in higher-order epitaxy, where commensurate growth occurs with a period defined by integer multiples of the lattice constants. Despite its potential, higher-order epitaxy is rarely used to enhance material properties or induce…

Superconducting Nanowire Single Photon Detectors based on NbRe nitride ultrafilms
The influence of the reactive DC sputtering parameters on the superconducting properties of NbReN ultrathin films was investigated. A detailed study of the current-voltage characteristics of the plasma was performed to optimize the superconducting critical temperature, Tc. The thickness dependence of Tc for the films deposited under different conditions was analyzed down to the ultrathin limit. Optimized films were used to fabricate superconducting nanowire single photon detectors which, at T=3…

Probing the accreting millisecond X-ray pulsar SAX J1808.4-3658 using the evolution of its spectral and aperiodic timing properties
Understanding accretion components in neutron star (NS) low mass X-ray binary (LMXB) systems is important to probe fundamental aspects of accretion mechanism and evolution of the system constraining its physical properties. Here, we present spectral and aperiodic timing analyses of the NICER and AstroSat data from the accretion powered millisecond X-ray pulsar (AMXP) SAX J1808.4-3658 during its 2022 outburst. We find that emissions from a softer accretion disk and a harder, centrally located, c…

Light-programmable reorientation of the crystallographic c-axis of Tellurium thin films
Tellurium (Te), a two-dimensional material with pronounced structural anisotropy, exhibits exceptional electrical and optical properties that are highly sensitive to its crystallographic orientation. However, conventional synthesis techniques offer limited control over the in-plane alignment of Te's crystallographic c-axis, hindering large-scale integration. Here, we report a novel, non-contact method to dynamically manipulate the c-axis orientation of Te thin films using linearly polarized pic…

Julia sets appear quasiconformally in the Mandelbrot set, II: A parabolic proof
Following the ideas of A.~Douady, we give an alternative proof of the authors' result: for any boundary point $c_0$ of the Mandelbrot set $M$, we can find small quasiconformal copies of $M$ in $M$ that are encaged in nested quasiconformal copies of the totally disconnected Julia set of a parameter arbitrarily close to $c_0$.

Comparison principle for Singular Fractional $ g- $Laplacian Problems
In this paper, we establish a novel comparison principle of independent interest and prove the uniqueness of weak solutions within the local Orlicz--Sobolev space framework, for the following class of fractional elliptic problems: \begin{equation*} (-Δ)^{s}_{g} u = f(x) u^{-α} + k(x) u^β, \quad u > 0 \quad \text{in } Ω; \quad u = 0 \quad \text{in } \mathbb{R}^{N} \setminus Ω, \end{equation*} where \( Ω\subset \mathbb{R}^{N} \) is a smooth bounded domain, \( α> 0 \), and \( β> 0 …

Measurement of radiant spectrum for excess heat generation in NiCu and Ni thin film during hydrogen gas desorption
Heat production in Ni-based thin films interacting with hydrogen gas was studied using a radiation calorimeter equipped with a composite photon-detector system. Measurements were performed on pure Ni foil and NiCu composite thin films. Electromagnetic radiation emitted from samples heated to approximately 1100 K in vacuum was recorded over the energy range of 0.05 - 2.5 eV. In this study,detailed spectra were obtained, particularly in the low-energy region below 0.5 eV. The peak of the thermal …

Exact $\ell^\infty$-separation radius of Sobol' sequences in dimension 2
Quasi-uniformity is a fundamental geometric property of point sets, crucial for applications such as kernel interpolation, Gaussian process regression, and space-filling experimental designs. While quasi-Monte Carlo methods are widely recognized for their low-discrepancy characteristics, understanding their quasi-uniformity remains important for practical applications. For the two-dimensional Sobol' sequence, Sobol' and Shukhman (2007) conjectured that the separation radius of the first $N$ poi…
