Topologically massive gravity on AdS spacetimes
Yun Soo Myung, Yong-Wan Kim, Young-Jai Park
We study the topologically massive gravity with a negative cosmological constant on AdS spacetimes by making use of dimensional reduction. For a constant dilaton, this two-dime…
Ruppeiner geometry and 2D dilaton gravity in the thermodynamics of black holes
Yun Soo Myung, Yong-Wan Kim, Young-Jai Park
We resolve the controversial issue of the geometric approach to the black hole thermodynamics. The geometric description of the equilibrium thermodynamics comes from Ruppeiner geom…
New attractor mechanism for spherically symmetric extremal black holes
Yun Soo Myung, Yong-Wan Kim, Young-Jai Park
We introduce a new attractor mechanism to find the entropy for spherically symmetric extremal black holes. The key ingredient is to find a two-dimensional (2D) dilaton gravity with…
BFT Embedding of Non-commutative Chiral Bosons
Wontae Kim, Young-Jai Park, Hyeonjoon Shin +1
A two dimensional model of chiral bosons in non-commutative field space is considered in the framework of the Batalin-Fradkin-Tyutin (BFT) Hamiltonian embedding method converting t…
Dirac Quantization of Restricted QCD
Y. M. Cho, Soon-Tae Hong, J. H. Kim +1
We discuss the quantization of the restricted gauge theory of SU(2) QCD regarding it as a second-class constraint system, and construct the BRST symmetry of the constrained system…
Improved BFT embedding having chain-structure
Yong-Wan Kim, Ee Chang-Young, Seung-Kook Kim +1
We newly revisit the gauge non-invariant chiral Schwinger model with a=1 in view of the chain structure. As a result, we show that the Dirac brackets can be easily read off from th…
