Some exactly solvable and tunable frustrated spin models
Francesco Caravelli
We discuss three exactly solvable spin models of geometric frustration. First, we discuss a 1-parameter subfamily of the 16 vertex model, which can be mapped to a planar Ising mode…
"Spectrally gapped" random walks on networks: a Mean First Passage Time formula
Silvia Bartolucci, Fabio Caccioli, Francesco Caravelli +1
We derive an approximate but explicit formula for the Mean First Passage Time of a random walker between a source and a target node of a directed and weighted network. The formula…
On the Degeneracy of Spin Ice Graphs, and its Estimate via the Bethe Permanent
Francesco Caravelli, Michael Saccone, Cristiano Nisoli
The concept of spin ice can be extended to a general graph. We study the degeneracy of spin ice graph on arbitrary interaction structures via graph theory. Via the mapping of spin…
Energy storage and coherence in closed and open quantum batteries
Francesco Caravelli, Bin Yan, Luis Pedro Garcia-Pintos +1
We study the role of coherence in closed and open quantum batteries. We obtain upper bounds to the work performed or energy exchanged by both closed and open quantum batteries in t…
Random Matrix Theory of the Isospectral twirling
Salvatore F. E. Oliviero, Lorenzo Leone, Francesco Caravelli +1
We present a systematic construction of probes into the dynamics of isospectral ensembles of Hamiltonians by the notion of Isospectral twirling, expanding the scopes and methods of…
Phases of memristive circuits via an interacting disorder approach
Francesco Caravelli, Forrest C. Sheldon
We study the phase diagram of memristive circuit models in the replica-symmetric case using a novel Lyapunov function for the dynamics of these devices. Effectively, the model we p…
