Key Topics in Nuclear Structure, 2005 We derive a boson Hamiltonian from a Nuclear Hamiltonian whose potential is expanded in pairing multipoles and determine the fermion-boson mapping of operators. We use a new method of bosonization based on the evaluation of the partition function restricted to the bosonic composites of interest.

Boson-fermion pairing in a boson-fermion environment [PDF]
Physical Review A, 2005 Propagation of a Boson-Fermion (B-F) pair in a B-F environment is considered. The possibility of formation of stable strongly correlated B-F pairs, embedded in the continuum, is pointed out. The new Fermi gas of correlated B-F pairs shows a strongly modified Fermi surface.

Composite Weak Bosons at the Large Hadronic Collider [PDF]
, 2016 In a composite model of the weak bosons the p-wave bosons are studied. The state with the lowest mass is identified with the boson, which has been discovered at the LHC. Specific properties of the excited bosons are discussed, in particular their decays into weak bosons and photons.

A Field Guide to Non‐Onsager Quantum Oscillations in Metals
Advanced Physics Research, EarlyView.The observation of quantum oscillations is usually taken as strong evidence for the existence of a Fermi surface according to the famous Onsager relation. The article reviews mechanisms that generate quantum oscillation frequencies that defy the Onsager relation where special emphasis is put on the recently discovered quasi‐particle lifetime ...

Anomalies and Bosonization [PDF]
Communications in Mathematical Physics, 2020 Recently, general methods of bosonization beyond 1+1 dimensions have been developed. In this article, we review these bosonizations and extend them to the case with boundary conditions. In particular, we study the case when the bulk theory is a $G$-symmetry protected topological phase and the boundary theory has a $G$ 't Hooft anomaly.

Unveiling Electron‐Phonon and Electron‐Magnon Interactions in the Weak Itinerant Ferromagnet LaCo2P2
Advanced Physics Research, EarlyView.Electron‐boson interactions in the weak itinerant ferromagnet LaCo2P2 are investigated, addressing both surface and bulk properties. The intricate renormalization of electronic states due to electron‐phonon and electron‐magnon interactions is examined, highlighting their distinct impacts on the electronic structure.

Determining the Structure of Higgs Couplings at the LHC [PDF]
, 2001 Higgs boson production via weak boson fusion at the CERN Large Hadron Collider has the capability to determine the dominant CP nature of a Higgs boson, via the tensor structure of its coupling to weak bosons.

Excited weak bosons and their decays [PDF]
, 2016 The weak bosons are bound states of fermions. Here the excitations of the weak bosons are discussed. Especially we study the decays of these excited states into weak bosons and photons.
