Maximum Entropy Variational Approach to Collective States
(Springer, 1993)
Artificial neural networks for density-functional optimizations in fermionic systems
(2019-12-01)
In this work we propose an artificial neural network functional to the ground-state energy of fermionic interacting particles in homogeneous chains described by the Hubbard model. Our neural network functional was proven ...
Inhomogeneous quenches in a free fermionic chain: Exact results

Numerical renormalization group computation of temperature dependent specific heat for a two-channel Anderson model
(Elsevier BVAmsterdam, 2012-03)
The Numerical Renormalization Group (NRG) is applied to diagonalize a two-channel Anderson model describing a local magnetic impurity embedded in a fermionic bath. In spite of the difficulty in computing the specific heat ...

The Numerical Renormalization Group (NRG) is applied to diagonalize a two-channel Anderson model describing a local magnetic impurity embedded in a fermionic bath. In spite of the difficulty in computing the specific heat ...
Entropy Bottlenecks at T →0 in Ce-Lattice and Related Compounds
(Springer/Plenum Publishers, 2015-01)
A number of specific heat (Formula presented.) anomalies are reported in Ce- and Yb-lattice compounds around 1 K which cannot be associated to usual phase transitions despite of their robust magnetic moments. Instead of a ...
Fidelity Witnesses for Fermionic Quantum Simulations
(2018-05-11)
The experimental interest and developments in quantum spin-1/2 chains has increased uninterruptedly over the past decade. In many instances, the target quantum simulation belongs to the broader class of noninteracting ...
Dynamical thermalization of interacting fermionic atoms in a sinai oscillator trap
(Multidisciplinary Digital Publishing Institute, 2019-08-08)
We study numerically the problem of dynamical thermalization of interacting cold fermionic atoms placed in an isolated Sinai oscillator trap. This system is characterized by a quantum chaos regime for one-particle dynamics. ...
