Even‐denominator 5/2 fractional state in trilayer graphene/V‐doped WSe2 heterostructure, mediated by proximitized magnetism, is demonstrated. An exceptionally high energy gap ∆5/2 (48 K) for the 5/2 state, significantly surpassing previous values in semiconductors and bilayer graphene (∆5/2 < 1 K) is reported.

Holography for Sp(2N c ) gauge dynamics: from composite Higgs to technicolour
We study Sp(2N c ) gauge dynamics with two Dirac fermion flavours in the fundamental representation. These strongly coupled systems underlie some composite Higgs models with a global symmetry breaking pattern SU(4)→Sp(4), leading to a light quartet of ...

Anomalous mass dimensions and Schwinger–Dyson equations boundary condition
Theories with large mass anomalous dimensions (γm) have been extensively studied because of their deep consequences for models where the scalar bosons are composite.

Plasmon Mediation of Charge Pairing in High Temperature Superconductors
A Bose-Einstein condensate (BEC) of a nonzero momentum Cooper pair constitutes a composite boson or simply a boson. We demonstrated that the quantum coherence of the two-component BEC (boson and fermion condensates) is controlled by plasmons. It has been

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Molecular interferometers: effects of Pauli principle on entangled-enhanced precision measurements
Feshbach molecules forming a Bose–Einstein condensate (BEC) behave as non-ideal bosonic particles due to their underlying fermionic structure. We study the observable consequences of the fermion exchange interactions in the interference of molecular BECs

Electroweak SU(2)L × U(1)Y model with strong spontaneously fermion-mass-generating gauge dynamics
Higgs sector of the Standard model (SM) is replaced by quantum flavor dynamics (QFD), the gauged flavor SU(3) f symmetry with scale Λ. Anomaly freedom requires addition of three ν R .

Giant Magnetocaloric Effect in a Honeycomb Spiral Spin‐Liquid Candidate
The frustrated honeycomb‐lattice single‐crystal GdZnPO, a spiral spin‐liquid (SSL) candidate, exhibits a giant magnetocaloric effect (with a large Grüneisen parameter Γm = 4.4 T−1) and exceptional cooling performance near the crossover magnetic field (Hc), surpassing other known magnetocaloric materials.

Modelling top partner-vector resonance phenomenology
We have analysed the observable consequences of the interactions of spin-1 resonances coupled to the invariant fermionic currents that arise in an SO(5) Composite Higgs set-up.

Holographic composite Higgs model building: soft breaking, maximal symmetry, and the Higgs mass
We study the emergence and phenomenological consequences of recently proposed new structures, namely soft breaking of the Higgs shift symmetry and ‘maximal symmetry’ of the composite sector, in holographic realizations of composite Higgs models.
