Gapped quantum liquids and topological order, stochastic local transformations and emergence of unitarity [PDF]
, 2015 In this work we present some new understanding of topological order, including three main aspects: (1) It was believed that classifying topological orders corresponds to classifying gapped quantum states. We show that such a statement is not precise.

Breaking embryo symmetry [PDF]
Science, 2017 Embryogenesis![Figure][1] Loss of cleavage symmetry in the early embryo PHOTO: E. KOROTKEVICH ET AL., DEV. CELL 40 , 235 (6 FEBRUARY 2017) © ELSEVIER For the first few cleavages, cells of the mammalian embryo are considered identical. Subsequently, symmetry is broken to generate the inner cell mass, which specifies the embryo proper, or the ...

Advanced Functional Materials, EarlyView.Fe‐cationic and P‐anionic coordination, as fabricated in Co0.75Fe0.25P/MWCNTs, effectively optimizes the adsorption of OER intermediates (OH*, O*), promoting direct O*─O* coupling and avoiding the formation of unstable OOH* intermediate. This process is accompanied by an asynchronous transfer of electrons and protons, resulting in the formation of a ...

Are supersymmetric models with minimal particle content under tension for testing at LHC?
Physics Letters B, 2016 In supersymmetric models with minimal particle content and without large left-right squarks mixing, the conventional knowledge is that the Higgs Boson mass around 125 GeV leads to top squark masses O(10) TeV, far beyond the reach of colliders.

Can experiments distinguish between Radiative Electroweak Symmetry breaking and Conventional breaking? [PDF]
arXiv, 2007 We present a comparative study of radiative electroweak symmetry breaking and conventional standard model breaking, and pose the question whether experiments can distinguish one breaking mode from the other. The importance of the problem lies in the fact that the two breaking modes have very different physical interpretations concerning the mechanism ...

A symmetry breaking scenario for QCD3 [PDF]
Journal of High Energy Physics, 2017 We consider the dynamics of 2+1 dimensional SU(N) gauge theory with Chern-Simons level k and Nf fundamental fermions. By requiring consistency with previously suggested dualities for Nf ≤ 2k as well as the dynamics at k = 0 we propose that the theory ...

Time crystal behavior of excited eigenstates
, 2017 In analogy to spontaneous breaking of continuous space translation symmetry in the process of space crystal formation, it was proposed that spontaneous breaking of continuous time translation symmetry could lead to time crystal formation. In other words,

Stability and absence of a tower of states in ferrimagnets
Physical Review Research, 2020 Antiferromagnets and ferromagnets are archetypes of the two distinct (type-A and type-B) ways of spontaneously breaking a continuous symmetry. Although type-B Nambu-Goldstone modes arise in various systems, the ferromagnet was considered pathological due

Supersymmetric space-time symmetry breaking sources
Journal of High Energy Physics, 2021 We construct new families of deformed supersymmetric field theories which break space-time symmetries but preserve half of the original supersymmetry. We do this by writing deformations as couplings to background multiplets. In many cases it is important
