Design of QAM-FBMC Waveforms Considering MMSE Receiver
Hyungsik Han, Namshik Kim, Hyuncheol Park
Due to its high spectral confinement characteristics and spectral efficiency, QAM-FBMC is considered a candidate waveform to replace CP-OFDM. QAM-FBMC has inevitable non-orthogonal…
Exciton Condensation in a Holographic Double Monolayer Semimetal
Gianluca Grignani, Andrea Marini, Namshik Kim +1
The formation of intra-layer and inter-layer exciton condensates in a model of a double monolayer Weyl semi-metal is studied in the strong coupling limit using AdS/CFT duality. We…
D7-anti-D7 bilayer: holographic dynamical symmetry breaking
Gianluca Grignani, Namshik Kim, Gordon W. Semenoff
We consider a holographic model of dynamical symmetry breaking in 2+1-dimenisons, where a parallel D7-anti-D7 brane pair fuse into a single object, corresponding to the U(1)XU(1)->…
D3-D5 Holography with Flux
Gianluca Grignani, Namshik Kim, Gordon W. Semenoff
It is shown that the Berezinski-Kosterlitz-Thouless phase transition that has been found in D3-D5 brane systems with nonzero magnetic field and charge density can also be found by…
Flavor-symmetry Breaking with Charged Probes
Joshua L. Davis, Namshik Kim
We discuss the recombination of brane/anti-brane pairs carrying brane charge in . These configurations are dual to co-dimension one defects in the ${\cal N}=…
Secrecy Capacity over Correlated Ergodic Fading Channel
Hyoungsuk Jeon, Namshik Kim, Minki Kim +2
We investigate the secrecy capacity of an ergodic fading wiretap channel in which the main channel is correlated with the eavesdropper channel. In this study, the full Channel Stat…
