Fluctuations in the New Inflationary Universe
Alan H. Guth,So-Young Pi +1 more
TL;DR: The spectrum of density perturbations in the new-inflationary-universe scenario is calculated in this article, where the main source is the quantum fluctuations of the Higgs field, which lead to fluctuations in the time at which the false vacuum energy is released.
Journal ArticleDOI
Chern-Simons modification of general relativity
Roman Jackiw,So-Young Pi +1 more
TL;DR: In this paper, General Relational Theory (GRS) is extended by promoting the three-dimensional gravitational Chern-Simons term to four dimensions, which is identical to one in which the embedding coordinate is itself a dynamical variable rather than a fixed, external quantity.
Journal ArticleDOI
Quantum mechanics of the scalar field in the new inflationary universe.
Alan H. Guth,So-Young Pi +1 more
TL;DR: In this article, the theory of the upside-down harmonic oscillator as a toy model is discussed, with particular emphasis on the fact that the system can be described at late times by a classical probability distribution.
Journal ArticleDOI
Chiral gauge theory for graphene.
Roman Jackiw,So-Young Pi +1 more
TL;DR: A chiral gauge theory is constructed to describe fractionalization of fermions in graphene and this work extends a recently proposed model, which relies on vortex formation.
Journal ArticleDOI
Testing non-commutative QED, constructing non-commutative MHD
TL;DR: The effect of non-commutativity on electromagnetic waves violates Lorentz invariance: in the presence of a background magnetic induction field b, the velocity for propagation transverse to b differs from c, while propagation along b is unchanged.
