Slowly Rotating Traversable Wormholes Supported by Radially Varying String‐Fluid Matter: From Regular Geometries to Photon Trajectories

Annalen der Physik, Volume 538, Issue 6, June 2026.
This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

Theoretical constraints on models with vectorlike fermions

Physical Review D
We provide a set of theoretical constraints on models in which the Standard Model field content is extended by vectorlike fermions and in some cases also by a real scalar singlet. Our approach is based on the study of electroweak vacuum stability, perturbativity of model couplings, and gauge couplings unification with the use of renormalization group ...

Nernst‐Effect‐Modulated Bilinear Magnetoelectric Resistance in Chiral Tellurium Nanosheets

SmartMat, Volume 7, Issue 3, June 2026.
This study systematically explores the bilinear magnetoelectric resistance (BMR) in electron‐doped Te nanosheets. Controlled experiments reveal that the observed out‐of‐plane BMR arises mainly from Joule‐heating‐induced Nernst effect. These findings highlight the crucial role of thermoelectric contributions in nonlinear carrier transport and offer ...

New physics in single resonant top quarks

Journal of High Energy Physics
Searches for new physics in the top quark sector are of great theoretical interest, yet some powerful avenues for discovery remain unexplored. We characterize the expected statistical power of the LHC dataset to constrain the single production of heavy ...

EFT Diagrammatica. Part II. Tracing the UV origin of bosonic D6 CPV and D8 SMEFT operators

Journal of High Energy Physics, 2022
In recent times, SMEFT, along with a superlative repertoire of theoretical and computational tools, has emerged as an efficacious platform to test the viability of proposed BSM scenarios. With symmetry as the backbone, higher mass dimensional (≥ 5) SMEFT

Imaging of Biphoton States: Fundamentals and Applications

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, Volume 38, Issue 25, 4 May 2026.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Phenomenology of Vector-like Fermions in Physics Beyond the Standard Model [PDF]

, 2018
The Standard model of particle physics provides a successful theory to understand the experimental results of the electroweak and strong interactions. However, it does not have a satisfactory explanation for the hierarchy problem. Many extensions of the Standard Model that solve the hierarchy problem result in new particles.

Multi-top signals of vectorlike quarks at the LHC

Journal of High Energy Physics
We point out that events with 6 or more top quarks may be observed at the LHC if certain particles exist at the TeV scale. In a model where a vectorlike quark of charge 2/3 decays into a top quark and a pseudoscalar particle, which subsequently decays ...
