Optimal observables for quantum-enhanced sensing and applications in a Floquet time crystal sensor
M. A. Manya, Andrei Tsypilnikov, Fernando Iemini
In this work, we discuss how to determine and implement feasible optimal observables for a metrology protocol that saturates the quantum Fisher information (QFI) bound. In particul…
Kondo effect in a two-dimensional electron gas in the Persistent Spin Helix regime
T. O. Puel, M. A. Manya, G. S. Diniz +2
The Kondo effect arises from many-body interactions between localized magnetic impurities and conduction electrons, affecting electronic properties at low temperatures. In this stu…
The cumulant Green's functions method for the single impurity Anderson model
T. M. Sobreira, T. O. Puel, M. A. Manya +5
Using the cumulant Green's functions method (CGFM), we study the single impurity Anderson model (SIAM). The CGFM starting point is a diagonalization of the SIAM Hamiltonian express…
Quantum impurity with 2/3 local moment in 1D quantum wires: an NRG study
P. A. Almeida, M. A. Manya, M. S. Figueira +3
We study a Kondo state that is strongly influenced by its proximity to an w^-1/2 singularity in the metallic host density of states. This singularity occurs at the bottom of the ba…
Spin-orbit coupling effects over thermoelectric transport properties in quantum dots
M. A. Manya, G. B. Martins, M. S. Figueira
We study the effects caused by Rashba and Dresselhaus spin-orbit coupling over the thermoelectric transport properties of a single-electron transistor, viz., a quantum dot connecte…
