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…
Spacetime quantum mechanics for bosonic and fermionic systems
N. L. Diaz, R. Rossignoli
We provide a Hilbert space approach to quantum mechanics where space and time are treated on an equal footing. Our approach replaces the standard dependence on an external classica…
Parallel-in-time quantum simulation via Page and Wootters quantum time
N. L. Diaz, Paolo Braccia, Martin Larocca +3
In the past few decades, researchers have created a veritable zoo of quantum algorithms by drawing inspiration from classical computing, information theory, and even from physical…
Conserved operators and exact conditions for pair condensation
Federico Petrovich, R. Rossignoli
We determine the necessary and sufficient conditions which ensure that an -particle fermionic or bosonic state has the form , whe…
Path Integrals from Spacetime Quantum Actions
N. L. Diaz, J. M. Matera, R. Rossignoli
The possibility of extending the canonical formulation of quantum mechanics (QM) to a space-time symmetric form has recently attracted wide interest. In this context, a recent prop…
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 Hamil…
