Theoretical Anatomy of Altermagnetic α-MnTe from Magnetism to Triple-resistance States

This theoretical study characterizes the magnetic properties and Néel temperature of the altermagnet α\alpha-MnTe using a symmetry-adaptive tensorial spin model and demonstrates its potential for high-density spintronic memory by predicting a tunneling magnetoresistance of approximately 5300% in sandwiched magnetic tunnel junctions.

Assessment of a Confined Dynamic Energy Shell in Terms of Quantum Teleportation and Quantum Tunneling: A Theoretical and Pre-Experimental Analysis of a Dual-Capsule Apparatus

This theoretical and pre-experimental analysis evaluates a dual-capsule apparatus designed to generate a confined dynamic energy shell, concluding that while it could theoretically support single-qubit teleportation via entangled pairs, it is fundamentally incapable of achieving macroscopic teleportation or tunneling due to insurmountable decoherence, qubit requirements, and exponentially suppressed transmission probabilities.

Coherence-to-Entanglement Conversion under Faulty CNOT Gates and Matched Idle Noise

This paper provides closed-form analytic benchmarks quantifying how four distinct classes of CNOT gate faults and matched idle noise degrade the conversion of single-qubit coherence into two-qubit entanglement, revealing that while coherent errors are mild and control-phase errors are invisible to this metric, stochastic faults cause proportional degradation with the bit-flip class exhibiting a unique angle-dependent signature.

Model for prediction of film composition in the DC Magnetron Sputtering of Fe-Cr-Ni-Mn-Cu and Al-Fe-Cr-Ni-Cu High-Entropy Alloys

This paper presents an algorithmic model that accurately predicts the compositional transfer of Fe-Cr-Ni-Mn-Cu and Al-Fe-Cr-Ni-Cu high-entropy alloys during DC magnetron sputtering, demonstrating that the calculated film compositions deviate from target values by less than ±1 wt% and align well with experimental results.

Exact Nonlinear Attitude Dynamics of Gravity-Gradient Spacecraft: Elliptic Libration Orbits, Separatrices and Energy-Based Stability Thresholds

This paper presents an exact, integrable solution for the nonlinear planar attitude dynamics of gravity-gradient spacecraft using Jacobi elliptic functions, establishing precise stability thresholds and demonstrating the significant inaccuracies of common polynomial approximations in predicting global phase-space behavior.

Surface Adsorption and Phase-Selective Electronic Modulation of Monolayer TaSe2

This study demonstrates that surface adsorption of various species (K, Fe, CO, O2) on monolayer TaSe2 induces phase-selective electronic modulation, ranging from rigid band shifts driven by charge transfer or interfacial dipoles to spectral broadening from local interactions, thereby offering a versatile method to tune the electronic properties of van der Waals materials.
