Exact solutions of hidden free fermion models
Hidden-free-fermion (HFF) Hamiltonians exhibit free-fermion spectra despite lacking an explicit quadratic representation, yet their algebraic provenance and periodic-boundary behavior remain open…Unbiased first-principles construction of complete tensorial spin Hamiltonians
Magnetic ground states are commonly predicted using spin Hamiltonians whose interaction terms are selected a priori, potentially overlooking the microscopic interactions that govern complex magnetic…Symmetry- and Property-Aware Crystal Generation with Reinforcement Learning for Inverse Materials Design
The inverse design of crystalline materials ultimately seeks structures with desired physical properties.Extreme-Scale Linear-Scaling Kohn-Sham DFT at 100 Million Atoms: Bridging Quantum Simulations and Experiments
Kohn-Sham density functional theory (DFT) remains the workhorse of ab initio materials simulation, yet cubic computational and quadratic memory scaling have confined calculations to a few hundred to…Fast quantum squeezing of a nanomechanical oscillator with an inverted potential
Nonclassical states of nano- and micro-mechanical motion enable measurements beyond the standard quantum limit and constitute a key resource for quantum sensing and metrology.An Exact Formulation of Phase-Space Electronic Structure Theory in One Dimension by Exploiting the Zero Curvature Condition
We show that, for the unique case of a system of electrons and nuclei in one dimension, the $\hGamma$ operator in phase space electronic structure theory has a zero non-Abelian curl.A Two-Mirror Faceted Projection System for EUV Lithography
We propose an all-reflective two-mirror projection system for extreme ultraviolet (EUV) lithography operating at exposure wavelengths of $13.5$~nm (Mo/Si) and $11.2$~nm (Ru/Be), delivering a…Parallel Circuit Execution for Scalable Quantum Computation
Today's quantum processors have tens to hundreds of physical qubits, but reliable execution of arbitrary circuits remains limited to fewer than 30 entangled qubits across hardware modalities.Non-equilibrium dissipative stabilization of s- and d-wave superconductivity
Stabilizing superconductivity beyond its equilibrium regime has been one of the quests of nonequilibrium state engineering.Noise Limits on Fault-Tolerant Fermionic Quantum Computing
Determining the highest amount of noise that quantum circuits can handle is an interesting and crucial task in the development of fault-tolerant quantum computation.Balanced and broadly-normed meta-generalized gradient approximation
Conventional semi-local density functional approximations for the exchange-correlation energy systematically underestimate fundamental band gaps.Quantum-accurate atomistic modeling of enzyme catalysis using a machine learned potential
Electronic rearrangements associated with bond forming/breaking in catalytic enzymes require quantum mechanical (QM) treatment beyond classical molecular mechanics (MM).Photonic reservoir computing with dimensionally compressed readout
This work addresses a hardware constraint in reservoir computing: the limited size of the readout layer imposed by systems with a physical readout.Recovering topological information of light by topological learning
The evolution of modern-day communication networks towards optical solutions with enhanced capacity and robustness is driving interest in topological light waves, exploiting their stability against…Physical policy gradient theorem for in situ stochastic-adjoint training
In situ adjoint training extracts parameter gradients directly from measurement, but has so far been limited to reciprocal or restricted systems.Ancilla mediated steady-state engineering in open quantum systems
Engineering the properties of a reservoir and its coupling to a quantum system is a powerful tool for simulating quantum thermodynamic processes and for generating otherwise inaccessible steady…Demonstration of room-temperature, magnetic-field-free, and ultralow-power spin-orbit torque logic device based on composition-uniform van der Waals magnet Fe3GaTe2
Van der Waals magnets have received blooming interest in material science and spintronics for the advantages of low magnetization, flexible stacking, strong tunability, and dangling-bond-free…End state of the experimental black-hole bomb
Rotating black holes can amplify incident waves through superradiant scattering.Hierarchical automation of scanning probe microscopy through agentic orchestration and algorithmic control
Rapid advances in agentic artificial intelligence enable scientific systems to interpret open-ended objectives, combine heterogeneous information, invoke specialized tools, and revise experimental…A Hybrid Simulation Code for Hall Thrusters and its Sensitivity to Numerical Parameters
Hybrid methods offer an attractive balance between computational efficiency and physical accuracy, playing an important guiding role in the design and optimization of Hall thrusters.
