Proposal for realizing unpaired Weyl points in a three-dimensional periodically driven optical Raman lattice

This paper proposes a feasible experimental scheme using periodically driven ultracold atoms in a 3D optical Raman lattice to realize unpaired Weyl points with tunable net chirality, thereby circumventing the Nielsen-Ninomiya theorem and enabling the observation of the chiral magnetic effect through a quantized charge current.

Repulsively Bound Hadrons in a $\mathbb{Z}_2$ Lattice Gauge Theory

This paper demonstrates that resonant pair-production terms in a $\mathbb{Z}_2$ lattice gauge theory enable the formation of stable, high-energy "repulsively bound" hadrons through a novel dynamical mechanism, a finding supported by matrix product state simulations and an effective model that suggests experimental realization on modern quantum hardware.

Nucleon to Roper transition amplitudes and electromagnetic form factors

This paper investigates the properties of the Roper resonance and nucleon-to-Roper electromagnetic transition amplitudes by analyzing quark degrees of freedom at high momentum transfer and incorporating baryon-meson contributions to explain low-to-intermediate momentum transfer data.

Forward-mode automatic differentiation for the tensor renormalization group and its relation to the impurity method

This paper proposes a forward-mode automatic differentiation framework for tensor renormalization group methods that offers superior accuracy in calculating thermodynamic quantities compared to conventional impurity methods, while establishing a theoretical link between the two approaches and providing practical procedures for extracting critical exponents.

Structural dissection of hadronic molecules: The $D^{(*)}\bar{K}^{(*)}$ family under QCD light-cone sum rules

This paper employs QCD light-cone sum rules to calculate the static electromagnetic properties of three $J^P=1^+$ charm-strange molecular tetraquark candidates, revealing that their magnetic moments are dominated by light quarks and providing quantitative benchmarks to distinguish molecular structures from compact multiquark interpretations.

Defect engineering spin centers in interacting many-body Su-Schrieffer-Heeger chains

This paper demonstrates that by introducing defects into a Su-Schrieffer-Heeger (SSH) chain, one can engineer an array of localized spin centers that form singlet or triplet qubits, providing a novel platform for quantum device manufacturing and many-body quantum simulations.

Gaussian Processes for Inferring Parton Distributions

This paper demonstrates that Gaussian Process Regression provides a robust, non-parametric Bayesian framework for reconstructing parton distribution functions from lattice QCD data, offering controlled uncertainty estimates and reduced model bias compared to traditional functional forms.

Towards a quantitative characterization of gravitational universality classes for order-4 random tensor models

The paper investigates fixed points in order-4 random tensor models to determine if they belong to the same universality class as the Reuter fixed point in continuum quantum gravity, ultimately concluding that they likely belong to different classes due to a discrepancy in the number of relevant directions.

Colour confinement and gauge-invariant field-strength correlations

This paper provides evidence that color confinement is caused by the dual superconductivity of the QCD vacuum by demonstrating that a gauge-invariant monopole creation operator has a non-zero vacuum expectation value in the confined phase.
