Quantum corrections to noncommutative kink
, 2008
"... We calculate quantum corrections to the mass of noncommutative kink in (1 + 1) dimensions for intermediate and large values of the noncommutativity parameter θ. All oneloop divergences are removed by a mass renormalization. For large θ quantum corrections to the mass grow linearly with θ signaling ..."

Quantum corrected geodesics
, 1999
"... We compute the gravitoninduced corrections to the trajectory of a classical test particle. We show that the motion of the test particle is governed by an effective action given by the expectation value (with respect to the graviton state) of the classical action. We analyze the quantum corrected eq ..."

Quantum corrections on fuzzy sphere
 Nucl. Phys. B665
"... We investigate quantum corrections in noncommutative gauge theory on fuzzy sphere. We study translation invariant models which classically favor a single fuzzy sphere with U(1) gauge group. We evaluate the effective actions up to the two loop level. We find nonvanishing quantum corrections at each ..."

QUANTUM CORRECTIONS TO DEEP BAGS ∗
, 1992
"... Nontopological solitons, or “bags, ” can arise when fermions acquire their mass through a Yukawa coupling to some scalar field. Bags have played an important role in models of baryons, nuclei, and more recently, in the idea that a Higgs condensate may form around a very heavy top quark. It has been ..."
Abstract
 Add to MetaCart
claimed that deep bags, which correspond to tightlybound states of fermions, will form when the Yukawa coupling is strong. Quantum corrections, however, are significant in this regime. We examine the effects of these quantum corrections on the formation of nontopological solitons in an exactly solvable
Perturbative Quantum Corrections to the Supersymmetric

"... Abstract: We present an explicit calculation of the oneloop quantum corrections to the mass and the two central charges of the kink solution of an N = (2,2) supersymmetric CP 1 model with twisted mass, using supersymmetry preserving dimensional regularization adapted to solitons. We find that the q ..."

Quantum Corrections to Nucleation Rates

"... In this paper we show how to compute in a consistent way nucleation rates in field theory at finite temperatures, with metastable vacuum. Using the semiclassical approach in field theory at finite temperature we show that the prefactor term can be calculated explicitly (in the thinwall approximatio ..."

We investigate solutions of the classical Einstein or supergravity equations that solve any set of quantum corrected Einstein equations in which the Einstein tensor plus a multiple of the metric is equated to a symmetric conserved tensor Tµν(gαβ, ∂τgαβ, ∂τ∂σgαβ,..., ) constructed from sums of terms ..."

Quantum Corrections to Monopoles
, 1998
"... We summarize our recent work on low energy quantum corrections to monopoles in N = 2 supersymmetric YangMills theory. The details maybe found in [1]. Most of our understanding of solitons in quantum field theory comes from semiclassical expansion about classical solutions. However, it was realized ..."
