Accelerated Discovery of Topological Conductors for Nanoscale Interconnects

Advanced Science, Volume 13, Issue 10, 18 February 2026.
Copper interconnects exhibit a sharp increase in resistivity at ultra‐scaled dimensions, threatening continued miniaturization of integrated circuits. The gapless surface states of topological semimetals provide conduction channels resistant to localization.

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 ...

Dimer models and conformal structures

Communications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.
Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

On the phase structure of vector-like gauge theories with massless fermions

Nuclear Physics B, 1982
Abstract We present a systematic expansion for studying an infrared-stable fixed point of gauge theories with massless fermions. These results are combined with information from strong coupling and large-NF expansions to sketch the phase diagrams for lattice gauge theories with massless fermions.

Vector-like tops from first generation quarks: the role of width and coupling chiralities in same-charge production at the LHC

Journal of High Energy Physics
In this paper, we tension the scope of the q q ¯ $$ q\overline{q} $$ , gg → T T ¯ $$ T\overline{T} $$ production process against that of the same-charge uu → TT one in searching for Vector-Like Quarks (VLQs) with electromagnetic charge +2/3 at the Large ...

Universality for fluctuations of counting statistics of random normal matrices

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We consider the fluctuations of the number of eigenvalues of n×n$n\times n$ random normal matrices depending on a potential Q$Q$ in a given set A$A$. The eigenvalues of random normal matrices are known to form a determinantal point process, and are known to accumulate on a compact set called the droplet under mild conditions on Q$Q$. When A$A$

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.

Symmetry Enhanced Unconventional Spin Current Anisotropy in a Collinear Antiferromagnet

Advanced Functional Materials, Volume 36, Issue 3, 8 January 2026.
Spin‐orbit torques (SOTs) are investigated in epitaxial FeSn, a topological antiferromagnet with kagome lattice symmetry. Combining experimental and theoretical approaches, the study identifies a six‐fold conventional damping‐like spin‐orbit torque (DL SOT), along with the coexistence of both six‐fold and uniaxial unconventional field‐like torque (FL ...

Muon ($g-2$) in $U(1)_{L_μ-L_τ}$ Scotogenic Model Extended with Vector like Fermion

, 2022
The latest results of anomalous muon magnetic moment at Fermilab show a discrepancy of 4.2 $σ$ between the Standard Model (SM) prediction and experimental value. In this work, we revisit $U(1)_{L_μ-L_τ}$ symmetry with in the paradigm of scotogenic model which explains muon ($g-2$) and neutrino mass generation, simultaneously.
