Mutual Information as a Two-Point Correlation Function in Stochastic Lattice Models
Ulrich Müller, Haye Hinrichsen
In statistical physics entropy is usually introduced as a global quantity which expresses the amount of information that would be needed to specify the microscopic configuration of…
Entropy Production of Nonequilibrium Steady States with Irreversible Transitions
Somayeh Zeraati, Farhad H. Jafarpour, Haye Hinrichsen
In nature stationary nonequilibrium systems cannot exist on their own, rather they need to be driven from outside in order to keep them away from equilibrium. While the internal me…
Entanglement versus mutual information in quantum spin chains
Jaegon Um, Hyunggyu Park, Haye Hinrichsen
The quantum entanglement of a bipartite quantum Ising chain is compared with the mutual information between the two parts after a local measurement of the classical spin co…
Magnetic vortices induced by a moving tip
Martin P. Magiera, Alfred Hucht, Haye Hinrichsen +2
A two-dimensional easy-plane ferromagnetic substrate, interacting with a dipolar tip which is magnetised perpendicular with respect to the easy plane is studied numerically by solv…
Fixed-Energy Sandpiles Belong Generically to Directed Percolation
Mahashweta Basu, Urna Basu, Sourish Bondyopadhyay +2
Fixed-energy sandpiles with stochastic update rules are known to exhibit a nonequilibrium phase transition from an active phase into infinitely many absorbing states. Examples incl…
Entropy-based Tuning of Musical Instruments
Haye Hinrichsen
The human sense of hearing perceives a combination of sounds 'in tune' if the corresponding harmonic spectra are correlated, meaning that the neuronal excitation pattern in the inn…
