This paper introduces MDHaloEnv, a Gymnasium-based reinforcement learning environment utilizing Proximal Policy Optimization and theoretically grounded Markov Decision Process improvements to automate and enhance the microradian-level alignment of crystals in the TWOCRYST experiment, thereby improving commissioning efficiency for future LHC-based double-channeling studies.
This paper demonstrates that active oscillator ensembles governed by chiral symmetry breaking and complementary interactions self-organize into autonomous, biomimetic transport networks by exploiting internal dynamical frustration to achieve optimal routing and self-repair, thereby establishing a decentralized, autopoietic computational substrate rooted in weak ergodicity breaking.
This paper establishes a one-to-one correspondence between quantum blobs (viewed as geometric monads) and generalized coherent states, utilizing this link to define a class of Toeplitz operators that extends anti-Wick quantization and enables a generalized phase-space formulation of density matrices.
This paper demonstrates that in a three-particle quantum walk, the weak-valued single-particle reduced density matrix can exhibit a Cheshire-cat-like structure where the local particle density vanishes identically while off-diagonal coherence remains finite, revealing a distinct separation between conditional density and coherence in many-body quantum systems.
Contrary to the prevailing belief that dielectric packing enhances non-thermal plasma performance, this study demonstrates that a bare dielectric barrier discharge reactor outperforms a TiO₂-packed bed in toluene removal by maintaining higher electron energy and oxidative species concentrations while avoiding the surface quenching and catalyst deactivation caused by carbon deposition in the packed configuration.
This paper develops a microscopic theory of Van Vleck excitonic magnetism in ruthenium pyrochlores, demonstrating how strong spin-orbit coupling drives the condensation of triplon excitations from a nonmagnetic singlet ground state into various magnetic orders, with specific application to Nd2Ru2O7 near an excitonic quantum critical point.
This paper introduces a Refined Optimal and Modified Homotopy Perturbation Method (ROM-HPM) that provides a direct semi-analytical framework for solving the full two-dimensional incompressible Navier-Stokes equations with pressure correction, successfully capturing complex flow physics in Newtonian and non-Newtonian microchannels while demonstrating superior computational efficiency and accuracy compared to conventional CFD approaches.
This paper investigates the thermodynamic performance of quantum heat engines and refrigerators based on a two-spin Skew Ising model, revealing that while the Carnot cycle exhibits universal entropy-driven behavior, the Otto cycle displays a richer structure governed by the interplay of energy spectra and nonequilibrium populations, ultimately demonstrating how tuned interactions and anisotropy can enhance thermodynamic efficiency.
This study demonstrates that low-dose gamma-ray irradiation enhances the charge carrier mobility and modifies the magnetoelectric and thermoelectric properties of ZrO₂-doped Bi₀.₈₅Sb₀.₁₅ alloys at cryogenic temperatures by inducing acceptor-type defects and altering electron scattering mechanisms.
This paper investigates a hybrid expansion cosmology within f(R, Σ, T) gravity, demonstrating through observational Hubble and Pantheon+ data that the model successfully reproduces the Universe's transition from deceleration to acceleration while remaining consistent with current constraints.
