Quantum heat machines enabled by twisted geometry
Cleverson Filgueiras, Moises Rojas, Edilberto O. Silva +1
In this paper, we analyze the operation of an Otto cycle heat machine driven by a non-interacting two-dimensional electron gas on a twisted geometry. We show that due to both the e…
Effect of induced transition on the quantum entanglement and coherence in two-coupled double quantum dots system
Zakaria Dahbi, Maron F. Anka, Mostafa Mansour +2
Studying quantum properties in solid-state systems is a significant avenue for research. In this scenario, double quantum dots (DQDs) appear as a versatile platform for technologic…
Thermal entanglement and quantum coherence of a single electron in a double quantum dot with Rashba Interaction
Merynilda Ferreira, Onofre Rojas, Moises Rojas
In this work, we study the thermal quantum coherence and fidelity in a semiconductor double quantum dot. The device consists of a single electron in a double quantum dot with Rashb…
Impurity-induced increase in the thermal quantum correlations and teleportation in an Ising-XXZ diamond chain
Saulo L. L. Silva, Moises Rojas
In this work we analyze the quantum correlations in a spin-1/2 Ising-XXZ diamond chain with one plaquette distorted impurity. We have shown that the introduction of impurity into t…
Thermal quantum correlations in two gravitational cat states
Moises Rojas, Iarley P. Lobo
We consider the effect of a thermal bath on quantum correlations induced by the gravitational interaction in the weak field limit between two massive cat states, called gravitation…
Two Coupled Double Quantum Dots Systems as an working substance for Heat Machines
Jefferson Luan D. de Oliveira, Moises Rojas, Cleverson Filgueiras
This paper presents a conceptual design for quantum heat machines using a pair of coupled double quantum dots (DQDs), each DQD with an excess electron to interact, as an working su…
