Stochastic learning flow: moment equations for stochastic gradient descent at finite step size
Analytical theories of learning in deep networks often assume gradient flow, discarding the finite step size and batch noise of stochastic gradient descent (SGD).Quantum banking system for secure cash withdrawal
A quantum-secure withdrawal framework is presented by replacing reproducible classical credentials with quantum tokens for authentication.PhysicsNeMo-Mesh: GPU-Native Meshes and Simulation Cases for Physics AI
PhysicsNeMo-Mesh is the mesh module of the open-source PhysicsNeMo library.Certified Access: Test-Time Compute on Conservative Physics-Structured AI Memory
Test-time compute mechanisms, such as retries, confidence-based escalation and non-local routing, are conventionally deployed as black-box additions to trained models.HERA: Assessing an Autonomous Agent for Quantum Device Measurement
Large language model agents have begun to carry out laboratory measurements, but their scientific conclusions are useful only if they hold up under scrutiny.Volumetric Nanophotonics for Enhanced Scintillation and Remote Light Outcoupling
Nanophotonic patterning is a promising approach to enhancing light extraction in scintillator materials, with the potential to improve performance in applications such as medical imaging and…A rhombic spin-1 interpretation of a room-temperature GaN emitter
Single defects in GaN show optically detected magnetic resonance at room temperature.Time-Switching Energy-Harvesting Quantum Relay-Assisted FSO Communication with Displaced Squeezed Signaling
This paper investigates a quantum relay-assisted free-space optical (FSO) communication system in which a decode-and-forward relay is powered by time-switching optical energy harvesting and forwards…The Korean Space Telescope (KST): A Dedicated Space Observatory for the Dark Universe
The Korean Space Telescope (KST) is a next-generation 1.4-meter wide-field space observatory, a dedicated probe of the dark sector.Data Driven Modeling of a Magnetic Newton's Cradle using the Optimization of a Discrete Loss
We investigate the dynamics of a magnetic Newton's cradle (MNC) using experiments, simulations through forward and inverse data driven models.virasoro_blocks: Software for the 2d bootstrap
We introduce virasoro_blocks, software that computes Virasoro conformal blocks at any central charge in a form suitable for the numerical bootstrap.A Low-Dimensional Chemical Representation of High-Resolution Stellar Disk Spectra: Residual Abundance Signatures
Stellar abundances are generated by complex chemical enrichment pathways yet show strong correlation structure.Reverse Quantum Annealing for Ground-State Energy Calculation in Molecule
We present the results of our reverse quantum annealing computations of the ground-state energies of alkaline-earth monofluoride molecules.Beyond energy bounds: comparing Schrödinger eigenstates
We derive eigenstate comparisons from ordered Schrödinger operators, extending energy bounds to overlaps, spatial distributions and nodes.Signatures of Narrowband and Ultrashort-Pulse-Like Probing in Coherent Anti-Stokes Raman Scattering Using Twin Beams and Sum-Frequency Generation Readout
We theoretically investigate coherent anti-Stokes Raman scattering (CARS) driven by bright twin beams with sum-frequency generation (SFG) readout.Nonreciprocal coupling enables tunable exceptional-point response in non-Hermitian circuits
Exceptional points (EPs) exhibit characteristic square-root spectral responses to weak perturbations, with response magnitudes governed by configuration-dependent prefactors that are often…Resonance and Transition-Channel Competition in Cavity-Assisted Floquet-State Stabilization
Static coupling to a dissipative cavity has been proposed as a route to autonomously stabilize Floquet eigenstates.Force Sensing in a Recoverable Bosonic Quantum Memory
In continuous-variable quantum information, sensing and quantum error correction in the same mode face an intrinsic trade-off: sensors must accumulate weak external displacements, whereas bosonic…Geometric Rényi divergence and RLD Fisher information under quantum processes without definite causal order
Quantum experiments without a definite causal order offer new ways to distinguish devices, estimate physical parameters, and communicate.Spatial-Mode Selection for Local Mineral Absorption Spectroscopy
Absorption-band depth measures the fractional decrease in mineral reflectance below its local continuum.
