Strong and precisely-controlled interactions between quantum objects are essential for information processing, simulation, sensing, the formation of exotic matter. A well-established paradigm coupling otherwise weakly-interacting is to use auxiliary bosonic excitations mediate interactions. Important examples include photon-mediated atoms, superconducting qubits, color centers in diamond, phono...

Studies of the spin, parity and tensor couplings of the Higgs boson in the H → Z Z∗ → 4 , H → WW ∗ → eνμν and H → γ γ decay processes at the LHC are presented. The investigations are based on 25 fb−1 of pp collision data collected by the ATLAS experiment at √ s = 7 TeV and √s = 8 TeV. The Standard Model (SM) Higgs boson hypothesis, corresponding to the quantum numbers J P = 0+, is tested agains...

Recently, Spielman et al have found a new type of Goldstone boson in quantum Hall effect in bilayers. The Goldstone boson is accompanied with a phase transition or broken symmetry. In the vacuum state if there is a broken symmetry, then a massless particle is emitted. Spielman et al have discovered such a quasiparticle. However, it remains to be proved that there is a phase transition associate...

We study the quantum phase transition occurring in an infinite homogeneous system of spin 1/2 fermions in a non-relativistic context. As an example we consider neutrons interacting through a simple spin-spin Heisenberg force. The two critical values of the coupling strength — signaling the onset into the system of a finite magnetization and of the total magnetization, respectively — are found a...

We study the stability of the pentaquarks uuddQ, uudsQ and udssQ (Q = c, b, or t) of positive parity in a constituent quark model based on Goldstone boson exchange interaction between quarks. The pentaquark parity is the antiquark parity times that of a quark excited to a p-shell. We show that the Goldstone boson exchange interaction favors these pentaquarks much more than the negative parity o...

An implication of the spontaneous chiral symmetry breaking in QCD is that at low energy and resolution there appear quasiparticles-constituent quarks and Goldstone bosons. Thus, light and strange baryons should be considered as systems of three constituent quarks with confining interaction and a chiral interaction that is mediated by Goldstone bosons between the constituent quarks. We show how ...
