Robustness of flat band superconductivity against disorder in a two-dimensional Lieb lattice model

Georges Bouzerar, Maxime Thumin·Dec 8, 2025

Recently, the possibility of high-temperature superconductivity (SC) in flat-band (FB) systems has been the focus of a great deal of activity. This study reveals that unlike conventional intra-band SC for which disorder has a dramatic impact, that as...

Mesoscopic superfluid to superconductor transition

Yehoshua Winsten, Doron Cohen·Dec 8, 2025

Spectrum tomography for the energy ($E$) of a ring-shaped Bose-Hubbard circuit is illustrated. There is an inter-particle interaction $U$ that controls superfluidity (SF) and the transition to the Mott Insulator (MI) regime. The circuit is coupled to...

Enhanced charging power in nonreciprocal quantum battery by reservoir engineering

Qi-Yin Lin, Guang-Zheng Ye, Can Li +2 more·Dec 8, 2025

We propose a scheme to achieve a nonreciprocal quantum battery (QB) in the non-Hermitian (NH) system, which can overcome the intrinsic dissipation and reverse flow constraints. The design is based on a charger and a battery, which are coherently coup...

Quantum Diamond Microscopy for Non-Destructive Failure Analysis of an Integrated Fan-Out Package-on-Package iPhone Chip

Bartu Bisgin, Marwa Garsi, Andreas Welscher +2 more·Dec 8, 2025

The increasing complexity of advanced semiconductor packages, driven by chiplet architectures and 2.5D/3D integration, challenges conventional failure localization methods such as lock-in thermography (LIT) and complicates current Failure Analysis (F...

Sharp values for all dynamical variables via Anti-Wick quantization

Simon Friederich·Dec 8, 2025

This paper proposes an approach to interpreting quantum expectation values that may help address the quantum measurement problem. Quantum expectation values are usually calculated via Hilbert space inner products and, thereby, differently from expect...

Tensor Network Lattice Boltzmann Method for Data-Compressed Fluid Simulations

Lukas Gross, Elie Mounzer, David M. Wawrzyniak +2 more·Dec 8, 2025

Resolving unsteady transport phenomena in geometrically complex domains is traditionally constrained by polynomial scaling of computational cost with spatial resolution. While methods based on tensor-network data representations or matrix-product sta...

On-Demand Microwave Single-Photon Source Based on Tantalum Thin Film

Ying Hu, Sheng-Yong Li, En-Qi Chen +4 more·Dec 8, 2025

Single-photon sources are crucial for quantum information technologies. Here, we demonstrate a microwave single-photon source fabricated using a tantalum-based thin film, whose favorable material properties enable high-quality and stable photon emiss...

Quantum algorithms for viscosity solutions to nonlinear Hamilton-Jacobi equations based on an entropy penalisation method

Shi Jin, Nana Liu·Dec 8, 2025

We present a framework for efficient extraction of the viscosity solutions of nonlinear Hamilton-Jacobi equations with convex Hamiltonians. These viscosity solutions play a central role in areas such as front propagation, mean-field games, optimal co...

Quantum computing of nonlinear reacting flows via the probability density function method

Jizhi Zhang, Ziang Yang, Zhaoyuan Meng +2 more·Dec 8, 2025

Quantum computing offers the promise of speedups for scientific computations, but its application to reacting flows is hindered by nonlinear source terms, the challenges of time-dependent simulations, and the difficulty of extracting meaningful physi...

Relativistic motion through a thermal bath as a thermodynamic resource

Rahul Shastri·Dec 8, 2025

We show that a localized quantum system following an arbitrary stationary trajectory and weakly interacting with a stationary thermal bath of a massless scalar field is generically driven into a non-Gibbs steady state by relative motion alone, even w...

Exponentially accelerated relaxation and quantum Mpemba effect in open quantum systems

Emerson Lima Caldas, Diego Paiva Pires·Dec 8, 2025

We investigate the quantum Mpemba effect in the relaxation of open quantum systems whose effective dynamics is described by Davies maps. We present a class of unitary transformations built from permutation matrices that, when applied to the initial s...

Site-controlled quantum dot arrays edge-coupled to integrated silicon nitride waveguides and devices

John O'Hara, Nicola Maraviglia, Mack Johnson +7 more·Dec 8, 2025

The scalability of quantum photonic integrated circuits opens the path towards large-scale quantum computing and communication. To date, this scalability has been limited by the stochastic nature of the quantum light sources. Moreover, hybrid integra...

Mediated Transmission of Quantum Synchronization in Star Networks

Shuo Dai, Ran Qi·Dec 8, 2025

Synchronization transmission describes the emergence of coherence between two uncoupled oscillators mediated by their mutual coupling to an intermediate one. In classical star networks, such mediated coupling gives rise to remote synchronization--whe...

Artificial Intelligence and Nuclear Weapons Proliferation: The Technological Arms Race for (In)visibility

David M. Allison, Stephen Herzog·Dec 8, 2025

A robust nonproliferation regime has contained the spread of nuclear weapons to just nine states. Yet, emerging and disruptive technologies are reshaping the landscape of nuclear risks, presenting a critical juncture for decision makers. This article...

Anomalous Wave-Packet Dynamics in One-Dimensional Non-Hermitian Lattices

Yanyan He, Tomoki Ozawa·Dec 8, 2025

Non-Hermitian (NH) systems have attracted great attention due to their exotic phenomena beyond Hermitian domains. Here we study the wave-packet dynamics in general one-dimensional NH lattices and uncover several unexpected phenomena. The group veloci...

On the emergence of preferred structures in quantum theory

Antoine Soulas, Guilherme Franzmann, Andrea Di Biagio·Dec 8, 2025

We assess the possibilities offered by Hilbert space fundamentalism, an attitude towards quantum physics according to which all physical structures (e.g. subsystems, locality, spacetime, preferred observables) should emerge from minimal quantum ingre...
