Holographic thermalization in Gauss-Bonnet gravity with de Sitter boundary
Shao-Jun Zhang, Bin Wang, Elcio Abdalla +1
We introduce higher-derivative Gauss-Bonnet correction terms in the gravity sector and we relate the modified gravity theory in the bulk to the strongly coupled quantum field theor…
Dynamically generated gap from holography in the charged black brane with hyperscaling violation
Xiao-Mei Kuang, Eleftherios Papantonopoulos, Bin Wang +1
We holographically investigate the effects of a dipole coupling between a fermion field and a gauge field on the dual fermionic sector in the charged gravity bulk with hyper…
Formation of Fermi surfaces and the appearance of liquid phases in holographic theories with hyperscaling violation
Xiao-Mei Kuang, Eleftherios Papantonopoulos, Bin Wang +1
We consider a holographic fermionic system in which the fermions are interacting with a U(1) gauge field in the presence of a dilaton field in a gravity bulk of a charged black hol…
Extremal Hairy Black Holes
P. A. Gonzalez, Eleftherios Papantonopoulos, Joel Saavedra +1
We consider a gravitating system consisting of a scalar field minimally coupled to gravity with a self-interacting potential and an U(1) electromagnetic field. Solving the coupled…
Duality between zeroes and poles in holographic systems with massless fermions and a dipole coupling
James Alsup, Eleftherios Papantonopoulos, George Siopsis +1
We discuss the zeroes and poles of the determinant of the retarded Green function () at zero frequency in a holographic system of charged massless fermions interacting vi…
Black Holes in Bi-scalar Extensions of Horndeski Theories
Christos Charmousis, Theodoros Kolyvaris, Eleftherios Papantonopoulos +1
We study certain bi-scalar-tensor theories emanating from conformal symmetry requirements of Horndeski's four-dimensional action. The former scalar is a Galileon with shift symmetr…
