Shaping causality: programmable nonlocal signal generation in long-range spin systems
Shreyas Sadugol, Giuseppe Luca Celardo, Fausto Borgonovi +1
Understanding how information spreads in non-relativistic many-body systems is a central issue for quantum information processing. While short-range interactions confine informatio…
Enhancement of magnetic anisotropy barrier in long range interacting spin systems
F. Borgonovi, G. L. Celardo
Magnetic materials are usually characterized by anisotropy energy barriers which dictate the time scale of the magnetization decay and consequently the magnetic stability of the sa…
Dynamics of random dipoles : chaos {\it vs} ferromagnetism
F. Borgonovi, G. L. Celardo
The microcanonical dynamics of an ensemble of random magnetic dipoles in a needle has been investigated. Analyzing magnetic reversal times, a transition between a chaotic paramagne…
Magnetic Reversal Time in Open Long Range Systems
F. Borgonovi, G. L. Celardo, B. Goncalves +1
Topological phase space disconnection has been recently found to be a general phenomenon in isolated anisotropic spin systems. It sets a general framework to understand the emergen…
The Topological Non-connectivity Threshold and magnetic phase transitions in classical anisotropic long-range interacting spin system
Roberto Trasarti-Battistoni, Fausto Borgonovi, Giuseppe Luca Celardo
We analyze from the dynamical point of view the classical characteristics of the Topological Non-connectivity Threshold (TNT), recently introduced in F.Borgonovi, G.L.Celardo, M.Ma…
The Topological Non-connectivity Threshold in quantum long-range interacting spin systems
F. Borgonovi, G. L. Celardo, R. Trasarti-Battistoni
Quantum characteristics of the Topological Non-connectivity Threshold (TNT), introduced in F.Borgonovi, G.L.Celardo, M.Maianti, E.Pedersoli, J. Stat. Phys., 116, 516 (2004), have b…
