We show that transmission under $\alpha \eta$ exposes information about the secret key ... More

More on N=1 Matrix Model Curve for Arbitrary NDec 15 2003Feb 17 2004Using both the matrix model prescription and the strong-coupling approach, we describe the intersections of n=0 and n=1 non-degenerated branches for quartic (polynomial of adjoint matter) tree-level superpotential in N=1 supersymmetric SO(N)/USp(2N) gauge ...

Phases of N=1 Supersymmetric SO/Sp Gauge Theories via Matrix ModelFeb 19 2003May 11 2003We extend the results of Cachazo, Seiberg and Witten to N=1 supersymmetric gauge theories with gauge groups SO(2N), SO(2N+1) and Sp(2N). By taking the superpotential which is an arbitrary polynomial of adjoint matter \Phi as a small perturbation of N=2 ... More

Geometry, D-branes and N=1 Duality in Four Dimensions with Product Gauge GroupMay 14 1997We study N=1 dualities in four dimensional supersymmetric gauge theories by D 6-branes wrapping around 3-cycles of Calabi-Yau threefolds in the type IIA string theory. We consider the models involving $SU(N_{c1})\times SU(N_{c2})$ product gauge group ... More

Perturbing Around A Warped Product Of AdS_4 and Seven-EllipsoidJul 06 2009Aug 08 2009We compute the spin-2 Kaluza-Klein modes around a warped product of AdS_4 and a seven-ellipsoid. This background with global G_2 symmetry is related to a U(N) x U(N) N=1 superconformal Chern-Simons matter theory with sixth order superpotential. The mass-squared ... More

Finite-size Effect of the Dyonic Giant Magnons in N=6 super Chern-Simons TheoryOct 13 2008Oct 21 2008We consider finite-size effects for the dyonic giant magnon of the type IIA string theory on AdS_4 x CP^3 by applying Luscher mu-term formula which is derived from a recently proposed S-matrix for the N=6 super Chern-Simons theory. We compute explicitly ... More

Finite-size effects of Membranes on AdS_4 x S_7Jul 03 2008Jul 13 2008We consider semi-classical solution of membranes on the AdS_4 x S^7. This is supposed to be dual to the N=6 super Chern-Simons theory with k=1 in a planar limit recently proposed by Aharony, Bergmann, Jafferis, and Maldacena (ABJM). We have identified ... More

Supersymmetric Domain Wall and RG Flow from 4-Dimensional Gauged N=8 SupergravityNov 14 2000Dec 21 2000By studying various, known extrema of 1) SU(3) sectors, 2) SO(5) sectors and 3) SO(3)xSO(3) sectors of gauged N =8 supergravity in four-dimensions, one finds that the deformation of seven sphere \S^7 gives rise to non-trivial renormalization group(RG) ...

Branes at $\C^4/\Ga$ Singularity from Toric GeometryMar 22 1999Apr 09 1999We study toric singularities of the form of $\C^4/\Ga$ for finite abelian groups $\Ga \subset SU(4)$. In particular, we consider the simplest case $\Ga=\Z_2 \times \Z_2 \times \Z_2$ and find explicitly charge matrices for partial resolutions of this orbifold ... More

Boundary Flows in general Coset TheoriesMay 17 1998May 20 1998In this paper we study the boundary effects for off-critical integrable field theories which have close analogs with integrable lattice models. Our models are the $SU(2)_{k}\otimes SU(2)_{l}/SU(2)_{k+l}$ coset conformal field theories perturbed by integrable ... More

On the Renormalization Group Flow in Two Dimensional Superconformal ModelsApr 30 2014We extend the results on the RG flow in the next to leading order to the case of the supersymmetric minimal models SM_p for p>> 1. We explain how to compute the NS and Ramond fields conformal blocks in the leading order in 1/p and follow the renormalization ... More

Higher Spin Currents in the Enhanced N=3 Kazama-Suzuki ModelJul 04 2016The N=3 Kazama-Suzuki model at the `critical' level has been found by Creutzig, Hikida and Ronne. We construct the lowest higher spin currents of spins (3/2, 2,2,2,5/2, 5/2, 5/2, 3) in terms of various fermions. In order to obtain the operator product ... More

Flavored Universe dispatched via Axion and NeutrinoNov 25 2016Motivated by the flavored Peccei-Quinn (PQ) symmetry for unifying flavor physics and string theory, we construct an explicit model by introducing an $U(1)$ symmetry as a fundamental one for rather recent but fast growing issues of astro-particle physics ...

Learning Pixel-level Semantic Affinity with Image-level Supervision for Weakly Supervised Semantic SegmentationMar 28 2018Apr 09 2018The deficiency of segmentation labels is one of the main obstacles to semantic segmentation in the wild. To alleviate this issue, we present a novel framework that generates segmentation labels of images given their image-level class labels. In this weakly ... More

The Conflict between Bell-Zukowski Inequality and Bell-Mermin InequalityFeb 11 2003Sep 18 2008We consider a two-particle/two-setting Bell experiment to visualize the conflict between Bell-\.Zukowski inequality and Bell-Mermin inequality. The experiment is reproducible by local realistic theories which are not rotationally invariant. We found that ... More

Chiral Algebras of Two-Dimensional SYK ModelsDec 12 2018We study chiral algebras in the $\bar{Q}$-cohomology of two dimensional SYK models with extended supersymmetry.
