A Non-Commutative Entropic Optimal Transport Approach to Quantum Composite Systems at Positive Temperature

  title={A Non-Commutative Entropic Optimal Transport Approach to Quantum Composite Systems at Positive Temperature},
  author={Dario Feliciangeli and Augusto Gerolin and Lorenzo Portinale},
This paper establishes new connections between many-body quantum systems, One-body Reduced Density Matrices Functional Theory (1RDMFT) and Optimal Transport (OT), by interpreting the problem of computing the ground-state energy of a finite dimensional composite quantum system at positive temperature as a non-commutative entropy regularized Optimal Transport problem. We develop a new approach to fully characterize the dual-primal solutions in such non-commutative setting. The mathematical… 


Quantum entropic regularization of matrix-valued optimal transport
This article introduces a new notion of optimal transport (OT) between tensor fields, which are measures whose values are positive semidefinite (PSD) matrices. This “quantum” formulation of optimal
Reduced Density Matrix Functional Theory for Bosons.
The solution of the underlying v-representability problem is found and the constrained search formalism is identified as the ideal starting point for constructing accurate functional approximations: the exact functionals F[γ] for this N-boson Hubbard dimer and general Bogoliubov-approximated systems are determined.
Matrix Optimal Mass Transport: A Quantum Mechanical Approach
This approach follows a control-theoretic optimization formulation of the Wasserstein-2 metric, having its roots in fluid dynamics, and utilizes certain results from the quantum mechanics of open systems, in particular the Lindblad equation.
An Entropic Gradient Structure for Lindblad Equations and Couplings of Quantum Systems to Macroscopic Models
We show that all Lindblad operators (i.e., generators of quantum Markov semigroups) on a finite-dimensional Hilbert space satisfying the detailed balance condition with respect to the thermal
One-body reduced density-matrix functional theory in finite basis sets at elevated temperatures
In this review we provide a rigorous and self-contained presentation of one-body reduced density-matrix (1RDM) functional theory. We do so for the case of a finite basis set, where density-functional
Positive contraction mappings for classical and quantum Schrödinger systems
The classical Schrodinger bridge seeks the most likely probability law for a diffusion process, in path space, that matches marginals at two end points in time; the likelihood is quantified by the
Gaussian optimizers for entropic inequalities in quantum information
It is shown that the restriction of the quantum-limited Gaussian attenuator to input states diagonal in the Fock basis coincides with the thinning, the analogue of the rescaling for positive integer random variables.
New methods for the ab-initio simulation of correlated systems
Strong electronic correlations are at the heart of many interesting phenomena. For the theoretical description of these materials, a proper treatment of the local atomic physics is required. We
Reduced Density Matrix Functional Theory at Finite Temperature: Theoretical Foundations
We present an ab-initio approach for grand canonical ensembles in thermal equilibrium with local or nonlocal external potentials based on the one-reduced density matrix. We show that equilibrium
Generalized Kohn-Sham system in one-matrix functional theory
A system of electrons in a local or nonlocal external potential can be described with one-matrix functional theory (1MFT), which is similar to density-functional theory (DFT) but takes the
