Deforming the Double‐Scaled SYK and Reaching the Stretched Horizon From Finite Cutoff Holography
Fortschritte der Physik, Volume 74, Issue 5, May 2026.ABSTRACT We study the properties of the double‐scaled SYK (DSSYK) model under chord Hamiltonian deformations based on finite cutoff holography for general dilaton gravity theories with Dirichlet boundaries. The formalism immediately incorporates a lower‐dimensional analog of TT¯(+Λ2)$\text{T}\overline{\text{T}}(+\Lambda _2)$ deformations, denoted T2 ...

ChemBioChem, Volume 27, Issue 8, April 2026.We introduce uracil–triazole–pyrene peptidomimetics whose tunable peptide linkers precisely control light emission, copper binding, and interactions with DNA and RNA. Fine structural adjustments unlock selective biomolecular recognition and striking metal‐ and membrane‐responsive fluorescence, paving the way for a new generation of multifunctional ...

|Vub| determination and testing of lepton flavour universality in semileptonic Bc → D(∗) decays
Journal of High Energy Physics, 2020 In light of prospects for measurements of B c → D (∗) lv decays in the upcoming Upgrade II of the LHC, we show that by using calculated B c → D (∗) form factors a competitive extraction of the |V ub | CKM matrix element from the B c → Dμ v ¯ μ $$ {B}_c\

Multi‐Scale Structural Insights Into Amphiphilic Model PEG–PCL Co‐Networks From LS and SANS
Macromolecular Chemistry and Physics, Volume 227, Issue 7, 14 April 2026.We present a multiscale structural study of amphiphilic PEG–PCL co‐networks combining light scattering in THF and small‐angle neutron scattering in D2O. This dual‐solvent approach reveals how solvent quality, polymer volume fraction, and PEG/PCL interactions govern static and dynamic correlation lengths, network homogeneity, and nanoscale domain ...

Quantum fermion superradiance and vacuum ambiguities on charged black holes
Journal of High Energy PhysicsUnlike a classical charged bosonic field, a classical charged fermion field on a static charged black hole does not exhibit superradiant scattering. We demonstrate that the quantum analogue of this classical process is however present.

Triple crossing positivity bounds for multi-field theories
Journal of High Energy Physics, 2021 We develop a formalism to extract triple crossing symmetric positivity bounds for effective field theories with multiple degrees of freedom, by making use of su symmetric dispersion relations supplemented with positivity of the partial waves, st null ...

Exact local distribution of the absolutely continuous spectral measure
Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.Abstract It is well‐established that the spectral measure for one‐frequency Schrödinger operators with Diophantine frequencies exhibits optimal 1/2$1/2$‐Hölder continuity within the absolutely continuous spectrum (Avila and Jitomirskaya, Commun. Math. Phys. 301 (2011), 563–581).

Helically Magnetized Plasma: From Photonic Fermi‐Arc Metal to Chirality‐Free Uniaxial Medium
Nanophotonics, Volume 15, Issue 5, 16 March 2026.A helically modulated magnetic field in magnetized plasma realizes a photonic Fermi‐arc metal, enabling full analytical tracking of Weyl node evolution. As modulation strengthens, opposing‐chirality Fermi arcs hybridize and recombine, yielding a chirality‐free uniaxial optical medium without conventional node annihilation.

More analytic bootstrap: nonperturbative effects and fermions
Journal of High Energy Physics, 2019 We develop the analytic bootstrap in several directions. First, we discuss the appearance of nonperturbative effects in the Lorentzian inversion formula, which are exponentially suppressed at large spin but important at finite spin.
