Propriedades óticas e magneto-óticas de monocamadas de MoWSe2
(Universidade Federal de São Carlos, 2023-01-23)
Two-dimensional (2D) semiconductors, such as transition-metal dichalcogenide (TMD) monolayers, have attracted intense interest in the last years because of their direct band gaps, valley properties and excitonic effects. ...
Quantum transistor using superconducting qubits
(Universidade Federal de São Carlos, 2022-09-23)
In recent times, quantum computation has become a flourishing field of research with increasing investment due to its promise to revolutionize computing, increasing the speed of information processing to levels far beyond ...
Ultracold bosons in random lattice potentials
(Universidade Federal de São Carlos, 2023-04-06)
The Bose-Hubbard model describes short-range interacting spinless bosons on a random lattice. This model is realized in ultracold atomic systems where quantum phase transitions can be observed. When loaded into a deep ...
Dopagem substitucional de peroviskitas com metais de transição 3d: um estudo ab initio
(Universidade Federal de São Carlos, 2022-10-04)
The global demand for energy has brought into focus the halide perovskites as materials
with high potential for applications in photovoltaic devices. Great progress has been made
in the last 10 years, demonstrating the ...
Efeitos de dimensionalidade em perovskitas de haletos para aplicações em células solares: um estudo ab initio
(Universidade Federal de São Carlos, 2022-10-07)
The structural stability and toxic lead are known obstacles to the current photovoltaic application of perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs). Herein, we perform a systematic study ...
Blockade and antiblockade effects with near-ground state neutral atoms
(Universidade Federal de São Carlos, 2022-09-06)
In this work we study the photon blockade and antiblockade effects in a system of neutral
atoms with a two-level structure, in the limit where induced dipole-dipole interactions
mediated by light are relevant. Such system ...
Magnetic fields as a tool to control superconducting devices
(Universidade Federal de São Carlos, 2023-10-16)
The quantum nature and dissipation-free flow of electric currents in superconducting materials have taken a central role as technological developments push forward the necessity of new methods for processing and dealing ...
Modelos de branas em (5+1) dimensões e o espectro dos leptóns carregados
(Universidade Federal de São Carlos, 2023-10-27)
This manuscript is concerned with a mechanism for explaining the mass spectrum of
the charged leptons within (5 + 1)-dimensional braneworlds. As a preliminary objective,
new two co-dimensional thick braneworlds ought to ...
Electromigration of multiterminal transport bridges
(Universidade Federal de São Carlos, 2023-03-09)
With the continued miniaturization of integrated circuits (ICs), the case of metallic tracks subjected to stress caused by transport currents has become a matter of increasing concern, as it puts at risk the reliability ...
Propriedades magnéticas e magnetoelétricas de compósitos multiferroicos de Pb[Zr0,53Ti0,47]O3/NixCo1-xFe2O4
(Universidade Federal de São Carlos, 2023-10-27)
New technologies are arising from the research and development of magnetism, especially those related to processing, information storage and sensors, are becoming increasingly important. in this regard, magnetoelectric ...
