Beyond Spontaneously Broken Symmetry in Bose-Einstein Condensates
Condensate treatment stage bell inequality particles quantum Angle the population oscillation
2014/12/19
Spontaneous symmetry breaking (SSB) for Bose-Einstein condensates cannot treat phase off-diagonal effects, and thus cannot explain Bell inequality violations. We describe another situation that is bey...
Spontaneously Broken Erlangen Program Offers a Bridge Between the Einstein and the Yang-Mills Theories

We shall give dynamics to our spacetime manifold by first identifying the local affine symmetry as the characterizing symmetry for our geometry \'a la Felix Klein, and then by prescribing 16 gauge vec...
Constructing a broken Lefschetz fibration of S^4 with a spun or twist-spun torus knot fiber

Abstract: Much work has been done on the existence and uniqueness of broken Lefschetz fibrations such as those by Auroux et al., Gay and Kirby, Lekili, Akbulut and Karakurt, Baykur, and Williams, but ...
Auroux, Donaldson and Katzarkov introduced broken Lefschetz fibrations as a generalization of Lefshcetz fibrations in order to describe near-symplectic 4-manifolds.We first study monodromy representat...

Penetration of nonquantized magnetic flux through a domain-wall bend in time-reversal symmetry broken superconductors
Penetration of nonquantized magnetic flux domain-wall superconductors
2010/11/22
It has been proposed that the superconductivity of Sr2RuO4 is characterized by pairing that is
unconventional and, furthermore, spontaneously breaks time-reversal symmetry. However, one of
the key e...
Infrared behavior in systems with a broken continuous symmetry: classical O(N) model vs interacting bosons
Infrared behavior in systems broken continuous symmetry interacting bosons
2010/11/23
In systems with a spontaneously broken continuous symmetry, the perturbative loop expansion
is plagued with infrared divergences due to the coupling between transverse and longitudinal fluctuations.A...
On the possibility of obtaining MOSFET-like performance and sub-60 mV/decade swing in 1D broken-gap tunnel transistors
obtaining MOSFET-like performance sub-60 mV/decade
2010/11/25
Tunneling field-effect transistors (TFETs) have gained a great deal of recent interest due to their potential to reduce power dissipation in integrated circuits. One major challenge for TFETs so far h...
Things to do with a broken stick

2010/11/30
The following problem sometimes called the spaghetti problem, goes back to at least 1854, being included in [20] on page 49. A good historical account can be found in a recent paper of Goodman ([6]). ...
Light Scalar Mesons as Manifestation of Spontaneously Broken Chiral Symmetry
Light Scalar Mesons Spontaneously Broken Chiral Symmetry
2010/3/15
Attention is paid to the production mechanisms of light scalars that reveal their nature. We reveal the chiral shielding of the \sigma(600) meson. We show that the kaon loop mechanism of the \phi radi...
A new actinic flux 4p-spectroradiometer：instrument design and application to clear sky and broken cloud conditions
actinic flux 4p-spectroradiometer clear sky broken cloud conditions
2009/3/11
A new 4p-spectroradiometer was developed for measuring actinic flux especially under cloudy conditions based on a fixed grating imaging spectrograph and a CCD-detector leading to a simultaneous measur...
Spectral actinic flux in the lower troposphere: measurement and 1-D simulations for cloudless, broken cloud and overcast situations
Spectral actinic flux lower troposphere 1-D simulations broken cloud overcast situations
2009/2/12
In September 2002, the first INSPECTRO campaign to study the influence of clouds on the spectral actinic flux in the lower troposphere was carried out in East Anglia, England. Measurements of the acti...
