Metastable Nonextremal Antibranes
/ Armas, J. ; Nguyen, N. ; Niarchos, V. ; Obers, N. A. ; et al
We find new and compelling evidence for the metastability of supersymmetrybreaking states in holographic backgrounds whose consistency has been the source of ongoing disagreements in the literature. [...]

${\mathrm{QCD}}_{3}$ with twoindex quarks, mirror symmetry, and fivebrane antiBIons near orientifolds
/ Armoni, Adi ; Niarchos, Vasilis
We consider a nonsupersymmetric HananyWitten type IIB brane configuration that realizes a threedimensional $USp\left(2N\right)$ gauge theory with quarks in the twoindex antisymmetric representation and $SO\left(4\right)$ flavor symmetry. [...]

Geometry of Higgsbranch superconformal primary bundles
/ Niarchos, Vasilis
It is known that the two and threepoint functions of Higgsbranch superconformal primaries in 4d $N=2$ superconformal field theories obey nonrenormalization theorems on $N=2$ superconformal manifolds. [...]

Aspects of Berry phase in QFT
/ Baggio, Marco ; Niarchos, Vasilis ; Papadodimas, Kyriakos
When continuous parameters in a QFT are varied adiabatically, quantum states typically undergo mixing — a phenomenon characterized by the Berry phase. [...]
