De-Sitter nonlinear sigma model and accelerating universe
Joohan Lee, Tae Hoon Lee, Taeyoon Moon +1
We consider a cosmology with a non-compact nonlinear sigma model.The target space is of de-Sitter type and four scalar fields are introduced.The potential is absent but cosmologica…
Isospin particle on with arbitrary number of supersymmetries
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study the supersymmetric quantum mechanics of an isospin particle in the background of spherically symmetric Yang-Mills gauge field. We show that on the number of supers…
Reply to "Comment on 'Scalar-tensor gravity coupled to a global monopole and flat rotation curves' "
Tae Hoon Lee, Byung Joo Lee
In Brans-Dicke theory of gravity we explain how the extra constant value in the formula for rotation velocities of stars in a galactic halo can be obtained due to the global monopo…
A complete solution of a Constrained System: SUSY Monopole Quantum Mechanics
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We solve the quantum mechanical problem of a charged particle on S^2 in the background of a magnetic monopole for both bosonic and supersymmetric cases by constructing Hilbert spac…
Supersymmetric Monopole Quantum Mechanics on Sphere
Soon-Tae Hong, Joohan Lee, Tae Hoon Lee +1
We study N=2 supersymmetric quantum mechanics of a charged particle on sphere in the background of Dirac magnetic monopole. We adopt CP(1) model approach in which the monopole inte…
Cosmic String Spacetime in Dilaton Gravity and Flat Rotation Curves
Tae Hoon Lee
In dilaton gravity theories, we consider a string-like topological defect formed during U(1) gauge symmetry-breaking phase transition in the early Universe, and far from the cosmic…
