, 2010 Within the covariant formulation of light-front dynamics, we calculate the state vector of a physical fermion in the Yukawa model. The state vector is decomposed in Fock sectors and we consider the first three ones: the single constituent fermion, the ...

physica status solidi (b), EarlyView.The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.The spin transition of a Mn(III) complex is investigated by tracking the evolution of the 1H and 13C NMR signals of individual sites under fast low‐temperature magic angle spinning conditions. The proposed experimental methodology combined with ab initio calculations of the paramagnetic NMR shifts provides a unique toolbox to study the electronic ...

Four-Dimensional N=1 Supersymmetric Yang-Mills Theory on the Lattice without Fine-Tuning
, 1997 We propose a method to formulate four-dimensional N=1 super Yang-Mills theory on the lattice without fine-tuning. We first show that four-dimensional Weyl fermion in a real representation, which is equivalent to Majorana fermion, can be formulated using ...

Room Temperature Evidence of PtTe2 Topological Semimetal Character
physica status solidi (RRL) – Rapid Research Letters, EarlyView.We report on a melt growth process for the synthesis of high‐quality PtTe2 crystals, as assessed by X‐ray diffraction and X‐ray photoemission spectroscopy characterization. By angle‐resolved photoemission spectroscopy investigation, we observe the expected topological features at cryogenic temperature and we demonstrate their stability even at room ...

Discrete symmetries for electroweak natural type-I seesaw mechanism
Nuclear Physics B, 2017 The naturalness of electroweak scale in the models of type-I seesaw mechanism with O(1) Yukawa couplings requires TeV scale masses for the fermion singlets.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis
Advanced Quantum Technologies, EarlyView.By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

A complex singlet extension of the Standard Model with a singlet fermion dark matter
Nuclear Physics BWe examine a complex singlet scalar extension of the Standard Model (CxSM) with an extra singlet fermion. Both the singlet scalar and fermion are dark matter (DM) candidates.

Nonperturbative definition of the standard models
Physical Review Research, 2020 The standard models contain chiral fermions coupled to gauge theories. It has been a longstanding problem to give such gauged chiral fermion theories a quantum nonperturbative definition.

One-loop renormalization group study of boson-fermion mixtures
, 2012 A weakly interacting boson-fermion mixture model was investigated using Wisonian renormalization group analysis. This model includes one boson-boson interaction term and one boson-fermion interaction term.
