CosmicGrain: An On-the-fly Dust Physics Module
We present CosmicGrain, a dust physics module built on Gadget-4 that models explicit dust superparticles that experience resolved gas-dust drag and radiation pressure, undergo collisional heating…GetGaia 2.0: automatic membership and systemic motions of stellar systems with Gaia
We present GetGaia 2.0, a public Python package that retrieves the Gaia data around a stellar system and selects its member stars automatically.Dust Survival in Lensed Quiescent Galaxies at $z>1$ Depends on How They Quench
The interstellar medium of massive quiescent galaxies holds key clues to how they quench, yet remain poorly understood.Dispersive Corrections to Electromagnetic Energy and Power Flux Are Imprints of Eliminated Degrees of Freedom
In a spatially dispersive medium the electromagnetic energy and flux are given by the frequency and wave-vector derivatives of the constitutive parameters, a result known as the Agranovich--Ginzburg…Coupling between molecular exchange qubits
Spin triangles are promising systems for defining and manipulating scalar degrees of freedom, such as chirality, partial spin sums, or combinations between the two.Anti-distinguishability of quantum channels
We study single-query perfect anti-distinguishability/exclusion tasks of finite quantum channel ensembles, primarily using associated Choi operators and process POVMs.An automated photometric pipeline for measuring the corotation radius of spiral galaxies
The corotation radius R_CR of a spiral galaxy marks the radius where the angular speed of the spiral pattern matches the orbital speed of the disk material.Entanglement Allocation for Quantum Integrated Sensing and Communication
Jointly supporting communication and distributed sensing over a shared, limited pool of entanglement resources is an attractive prospect for future quantum networks.Quantum identity authentication protocol via perturbed probability amplitudes
Quantum identity authentication is an effective solution for establishing mutual trust between communicating parties in the post-quantum era.COSMIO: A Benchmark for Cross-Survey Modality Imputation
Large-scale astronomical surveys define a heterogeneous, partially observed multi-survey learning setting: each object is observed by only a subset of surveys, while survey observations differ in…The vertical distribution of molecular gas in the fourth quadrant of the Milky Way
The vertical distribution of molecular gas in the Milky Way disk is poorly studied, especially in the 4th quadrant and the far side of the Galaxy.Hardware-Efficient Reinforcement-Learned Scheduling for Quantum LDPC Decoders
Quantum low-density parity-check (QLDPC) codes are promising for fault-tolerant quantum computing, but their decoding algorithms present significant hardware implementation challenges.Initialization-controlled fault sensitivity and force-balance plateaus in noisy variational quantum optimization
We study deep variational circuits for a periodic Heisenberg chain under local gate depolarization, at depths where noiseless training is coherently exact.Tidal Evolution of Satellite Dwarf Galaxies. I. Tidal Tracks of Stellar Mass and Structure
Satellite dwarf galaxies are reshaped by the tidal field of their host, a process that may account for part of the structural diversity of the observed dwarf population.Negative Junction Logarithms in Scalar Multipartite Entanglement
A three-region junction in a free real relativistic scalar vacuum in $2+1$ dimensions yields a strictly negative logarithmic contribution to genuine tripartite Rényi multi-entropy for every integer…Thermally enhanced magnon-phonon resonance in van der Waals antiferromagnet FePS3
Strong coupling between collective excitations provides a route to controlling quantum states of matter, yet its evolution under thermal fluctuations remains poorly understood.Extreme Multiwavelength Variability in the Recurrent Intermediate-type Changing-look Seyfert Galaxy SDSS J234728.73+242745.7
We report the discovery of the Seyfert galaxy J234728.73+242745.7 as a recurrent intermediate-type CLAGN with extreme optical/UV variability.On the universality of entanglement entropy in quantum field theory
The standard definition of entanglement entropy in quantum field theory requires regularizing the entangling surface and factorizing the Hilbert space, which in turn involves a choice of boundary…Information-Geometric Representation of Upper Bounds on Fluctuation Growth in Open Quantum Systems
Building on our earlier results for closed quantum systems, we investigate the dynamical evolution of quantum fluctuations and their connections to Fisher information and the quantum operations…Reasoning about Shared-Qubit Concurrency in Quantum Computing
In this paper, we develop a semantic model for the parallel execution of quantum circuits, providing a formal foundation for studying shared-qubit concurrency in quantum computing.
