Several novel approaches have been proposed to resolve the problem of time by relating it change. We argue using quantum information theory that Hamiltonian constraint in gravity cannot probe change, so be used obtain a meaningful notion time. This is due absence Fisher with respect time-reparametization invariant system. also observe inability this change can related its discriminate between s...

Differences between individuals are the raw material from which theories of the evolution and ontogeny of cognition are built. For example, when 4-year-old children pass a test requiring them to communicate the content of another's falsely held belief, while 3-year-olds fail, we know that something must change over the course of the third year of life. In the search for what develops or evolves...

The electromagnetic decay processes of excited hyperon states are a very sensitive probe of the structure of hyperons. We will argue that the recent measurements of electromagnetic decay rates indicate that the wave functions of the hyperon ground states should contain sizeable components of excited quark states (configuration mixing). Flavor-SU (3) is a broken symmetry and it appears that the ...

The Chern-Simons number as an order parameter : classical sphaleron transitions for SU(2)-Higgs field theories for m H ≈ 120 GeV Abstract The classical transitions between topologically distinct vacua in a SU (2)–Higgs model, using a Higgs field of mass approximately 120 GeV, is examined to probe the crossover region between the symmetric and broken phase. Assuming the Higgs mass is constant, w...

For materials that harbour a continuous phase transition, the susceptibility of the material to various fields can be used to understand the nature of the fluctuating order and hence the nature of the ordered state. Here we use anisotropic biaxial strain to probe the nematic susceptibility of URu2Si2, a heavy fermion material for which the nature of the low temperature 'hidden order' state has ...

We derive constraints on a simple quintessential inflation model, based on a spontaneously broken Φ theory, imposed by the Wilkinson Microwave Anisotropy Probe three-year data (WMAP3) and by galaxy clustering results from the Sloan Digital Sky Survey (SDSS). We find that the scale of symmetry breaking must be larger than about 3 Planck masses in order for inflation to generate acceptable values...

Supersymmetry implies that the trilinear couplings between gauge bosons and gauginos are equal to all orders. However if SUSY is broken and some of the superpartners have large SUSY breaking masses then they can induce non-decoupling deviations in this relation through radiative corrections. In this work we show that the deviation in the ratio g̃wχ̃γ̃ gγww from unity can be around 2.3% (3.3%) in h...
