History state formalism for time series with application to finance
F. Lomoc, N. Canosa, A. P. Boette +1
We present a method for analyzing general time series by employing the history state formalism of quantum mechanics. This formalism allows us to describe a complete evolution based…
Covariance-based method for eigenstate factorization and generalized singlets
Federico Petrovich, R. Rossignoli, N. Canosa
We derive a general method for determining the necessary and sufficient conditions for exact factorization of an eigenstate of a many-body Hamilto…
History states of one-dimensional quantum walks
F. Lomoc, A. P. Boette, N. Canosa +1
We analyze the application of the history state formalism to quantum walks. The formalism allows one to describe the whole walk through a pure quantum history state, which can be d…
Ground state separability and criticality in interacting many-particle systems
F. Petrovich, N. Canosa, R. Rossignoli
We analyze exact ground state (GS) separability in general particle systems with two-site couplings. General necessary and sufficient conditions for full separability, in the f…
Nonlinear effects on the dynamics of quantum harmonic modes coupled through angular momentum
N. Canosa, R. Rossignoli, Javier Garcia +2
We investigate nonlinear effects on the dynamics of entanglement and other quantum observables in a system of two harmonic modes coupled through angular momentum. The nonlinearity…
Separability and parity transitions in spin systems under nonuniform fields
N. Canosa, R. Mothe, R. Rossignoli
We examine the existence of completely separable ground states (GS) in finite spin- arrays with anisotropic couplings, immersed in a non-uniform magnetic field along one o…
