The Royal Swedish Academy of Sciences has decided to award the Nobel Prize …Nearby this angle, we discover a symmetry-broken Chern insulator (SBCI) state associated with a band filling of 7/2 as well as an incipient SBCI state associated with 11/3 filling. We further observe an anomalous Hall effect at zero field in all samples supporting SBCI states, indicating spontaneous time-reversal symmetry breaking and …How can metasurfaces with broken parity symmetry achieve asymmetric phase modulation of light? This paper presents a novel design and experimental demonstration of such metasurfaces, which can manipulate the phase and polarization of light in different directions. The paper also discusses the potential applications of this phenomenon in …We have computed symmetry broken and symmetry unbroken line and parabolic first two nontrivial solutions for general NLS equation and reverse space nonlocal NLS equation respectively.

The Universe is ...In short, broken-symmetry coupled cluster theory provides a straightforward methodology to predict magnetic exchange coupling constants, complementing approaches that target spin-eigenstates, such as equation-of-motion coupled cluster methods and complete-active-space techniques. It is especially reliable when employing the … On the other hand, if one rotated figure 3B by an arbitrary angle, it would still look like water! Ice has broken rotational symmetry: one can rotate figure 3A only by multiples of 60 degrees. It also has a broken translational symmetry: it's easy to tell if the picture is shifted sideways, unless one shifts by a whole number of lattice units. Phys. Rev.

D. M. Haldane and S. Raghu Phys. Rev. Lett. 100, 013904 – Published 10 January 2008 Symmetry breaking is a fundamental concept in particle physics. The most popular mechanism is the Higgs mechanism. Also radiative symmetry breaking (Coleman-Weinberg (CW) mechanism [1]) is well known. The CW mass is obtained when the tree level mass parameter is zero, i.e. the Higgs mass is induced by radiative corrections.
