Strong cooperativity and inhibitory effects in DNA multi-looping processes
Artur Garcia-Saez, J. Miguel Rubi
We show the existence of a high interrelation between the different loops that may appear in a DNA segment. Conformational changes in a chain segment caused by the formation of a p…
Area laws and entanglement distillability of thermal states
Daniel Cavalcanti, Alessandro Ferraro, Artur Garcia-Saez +1
We study the entanglement distillability properties of thermal states of many-body systems. Following the ideas presented in [D.Cavalcanti et al., arxiv:0705.3762], we first discus…
Thermal bound entanglement in macroscopic systems and area laws
A. Ferraro, D. Cavalcanti, A. Garcia-Saez +1
Does bound entanglement naturally appear in quantum many-body systems? We address this question by showing the existence of bound-entangled thermal states for harmonic oscillator s…
Distillable entanglement and area laws in spin and harmonic-oscillator systems
D. Cavalcanti, A. Ferraro, A. Garcia-Saez +1
We address the presence of non-distillable (bound) entanglement in natural many-body systems. In particular, we consider standard harmonic and spin-1/2 chains, at thermal equilibri…
Monogamy and ground-state entanglement in highly connected systems
Alessandro Ferraro, Artur Garcia-Saez, Antonio Acin
We consider the ground-state entanglement in highly connected many-body systems, consisting of harmonic oscillators and spin-1/2 systems. Varying their degree of connectivity, we i…
