The speed at which the magnetic interaction propagates along a chain of classic dipoles is discussed here. While in the quantum information counterpart for long-range interacting spins, where the speed of propagation of the information plays a paramount role, it is not strictly clear whether a light cone exists or not, here we provide numerical evidence that interacting dipoles do posses a linear light cone shortly after a perturbation takes place. Specifically, a power-law expansion occurs…

Nearly linear light cones in long-range interacting quantum systems.
TLDR
This work rules out the possibility that light cones of power-law interacting systems are bounded by a polynomial for α>2D and become linear as α→∞, suggesting that the velocity, as calculated from the slope of the light cone, may grow exponentially in time.
Persistence of locality in systems with power-law interactions.
TLDR
A new bound on the propagation of information in D-dimensional lattice models exhibiting 1/r^{α} interactions with α>D is derived, which qualitatively reproduce the short- and long-distance dynamical behavior following a local quench in an XY chain and a transverse-field Ising chain.
Supersonic quantum communication.
TLDR
It is proved that one can encounter accelerating excitations under the natural dynamics that allow for reliable transmission of information faster than any finite speed of sound.
Causality and quantum criticality in long-range lattice models.
TLDR
This work deduces the dynamic critical exponent, up to the two-loop order within the renormalization group theory, which is then used to characterize the emergent causal behavior of the long-range couplings.
Hierarchy of linear light cones with long-range interactions
In quantum many-body systems with local interactions, quantum information and entanglement cannot spread outside of a linear light cone, which expands at an emergent velocity analogous to the speed
Lieb-Robinson bounds and the generation of correlations and topological quantum order.
The Lieb-Robinson bound states that local Hamiltonian evolution in nonrelativistic quantum mechanical theories gives rise to the notion of an effective light cone with exponentially decaying tails.
Speed of Gravity
Still nowadays is not known: What is the gravity? Which is its speed?. However, in the world, the great majority of the physicists follow the General Relativity, which explains the gravity like the
Scale-invariant freezing of entanglement
We show that bipartite entanglement in an one-dimensional quantum spin model undergoing time evolution due to local Markovian environments can be frozen over time. We demonstrate this by using a
Fluctuation Theorem for Many-Body Pure Quantum States.
TLDR
The second law of thermodynamics and the nonequilibrium fluctuation theorem for pure quantum states are proved and can be experimentally tested by artificial isolated quantum systems such as ultracold atoms.
