Efficient Gaussian Simulations of Fermionic Open Quantum Systems
Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.Building upon Bravyi's fundamental theoretical framework, efficient classical simulation methods are reviewed and further developed for general fermionic Gaussian processes. The emphasis remains on a unified approach applicable to generic fermionic Gaussian operations.

Fermion Virtual Effects in $e^+ e^- -> W^+ W^-$ Cross Section
, 1996 We analyse the contribution of new heavy virtual fermions to the $e^+e^- \rightarrow W^+W^-$ cross section. We find that there exists a relevant interplay between trilinear and bilinear oblique corrections.

, 2016 The elucidation of the nature of new phenomena requires a multi-pronged approach to understand the essential physics that underlies it. As an example, we study the simplified model containing a new scalar singlet accompanied by vector-like quarks, as ...

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.

Optimal lattice domain-wall fermions with finite Ns
, 2003 I review the lattice formulations of vector-like gauge theories (e.g. QCD) with domain-wall fermions, and discuss how to optimize the chiral symmetry for any finite N_s (in the fifth dimension), as well as to eliminate its dependence on a_5.Comment: 7 ...

Flavor invariants for the SM with one singlet vector-like quark
Journal of High Energy PhysicsWe study the flavor invariants of the SM augmented by one singlet vector-like quark. Aided by the Hilbert series, we construct all the basic invariants with which any flavor invariant can be written as a polynomial.

Anomaly free Froggatt-Nielsen models of flavor
Journal of High Energy Physics, 2019 We introduce two anomaly free versions of Froggatt-Nielsen (FN) models, based on either G FN = U(1)3 or G FN = U(1) horizontal symmetries, that generate the SM quark and lepton flavor structures.

Fermion Condensate as Higgs substitute [PDF]
, 2011 A dynamical symmetry breaking model of electroweak interactions is investigated based on strongly interacting fermions. Vector-like fermions of different representations of the weak SU(2) form a symmetry breaking condensate and generate the lepton and ...

Dirac Leptogenesis with a Non-anomalous $U(1)^{\prime}$ Family Symmetry
, 2012 We propose a model for Dirac leptogenesis based on a non-anomalous $U(1)^{\prime}$ gauged family symmetry. The anomaly cancellation conditions are satisfied with no new chiral fermions other than the three right-handed neutrinos, giving rise to stringent
