Metastable Supersymmetry Breaking in a Cooling Universe (2007)
I put metastable supersymmetry breaking in a cosmological context. I argue that under reasonable assumptions, the cooling down early Universe favors metastable SUSY-breaking vacua over the stable...
Localized Backreacted Flavor Branes in Holographic QCD (2007)
Burrington, Benjamin A., Kaplunovsky, Vadim S., Sonnenschein, Jacob
We investigate the perturbative (in $g_s N_{D8}$) backreaction of localized D8 branes in D4-D8 systems including in particular the Sakai Sugimoto model. We write down the explicit expressions of the...
Quantum Deconstruction of 5D SQCD (2006)
Di Napoli, Edoardo, Kaplunovsky, Vadim S.
We deconstruct the fifth dimension of 5D SCQD with general numbers of colors and flavors and general 5D Chern-Simons level; the latter is adjusted by adding extra quarks to the 4D quiver. We use...
Unitary Matrix Model of a Chiral [SU(N)]^K Gauge Theory (2005)
Di Napoli, Edoardo, Kaplunovsky, Vadim S.
We build a matrix model of a chiral [SU(N)]^K gauge theory (5D SQCD deconstructed down to 4D) using random unitary matrices to model chiral bifundamental fields (N,N-bar) (without (N-bar,N)). We...
Chiral Rings of Deconstructive [SU(n_c)]^N Quivers (2004)
Di Napoli, Edoardo, Kaplunovsky, Vadim S., Sonnenschein, Jacob
Dimensional deconstruction of 5D SQCD with general n_c, n_f and k_CS gives rise to 4D N=1 gauge theories with large quivers of SU(n_c) gauge factors. We construct the chiral rings of such [SU(n_c)]^N...
Quantum Deconstruction of a 5D SYM and its Moduli Space (2002)
Iqbal, Amer, Kaplunovsky, Vadim S.
We deconstruct the fifth dimension of the 5D SYM theory with SU(M) gauge symmetry and Chern-Simons level k=M and show how the 5D moduli space follows from the non-perturbative analysis of the 4D...
Gorbatov,Elie, Kaplunovsky,Vadim S., Sonnenschein,Jacob, Theisen,Stefan, Yankielowicz,Shimon
Horava--Witten M theory -- heterotic string duality poses special problems for the twisted sectors of heterotic orbifolds. In [1] we explained how in M theory the twisted states couple to gauge...

On the duality between perturbative heterotic orbifolds and M-theory on T4/ZN (2000)
Kaplunovsky, Vadim S., Sonnenschein, Jacob, Theisen, Stefan, Yankielowicz, S.
The heterotic E8×E8 string compactified on an orbifold T4/ZN has gauge group G×G′ with (massless) states in its twisted sectors which are charged under both gauge group factors. In the dual...
Domain Walls in Supersymmetric Yang-Mills Theories (1998)
Kaplunovsky, Vadim S., Sonnenschein, Jacob, Yankielowicz, Shimon
We study BPS saturated domain walls in the supersymmetric SU(2) gauge theory. For a theory with a very light adjoint scalar (mass
Phenomenological Aspects of F-theory (1997)
Kaplunovsky, Vadim S., Louis, Jan
Stabilizing a heterotic string vacuum with a large expectation value of the dilaton and simultaneously breaking low-energy supersymmetry is a long-standing problem of string phenomenology. We...
Large-Volume String Compactifications, Revisited (1996)
Caceres, Elena, Kaplunovsky, Vadim S., Mandelberg, I. Michael
We reconsider the issue of large-volume compactifications of the heterotic string in light of the recent discoveries about strongly-coupled string theories. Our conclusion remains firmly negative...
Aspects of duality in N = 2 string vacua (1995)
Kaplunovsky, Vadim S., Louis, Jan, Theisen, Stefan
We collect further evidence for the proposed duality between N = 2 heterotic and type II string vacua in a specific model suggested by Kachru and Vafa. In the gauge sector the previous analysis is...
