Propagação de ondas aplicadas ao mapeamento geológico: formulação acústica

Revista Brasileira de Ensino de Física, 2021
O conceito de onda é recorrente nas ciências pura e aplicada, servindo de base para compreender desde terremotos, passando pelas telecomunicações e eletromagnetismo, até a difração de nêutrons, e.g., para citar um caso quântico.

Higgs sector of the MSSM: lepton flavor violation at colliders and neutralino dark matter [PDF]

, 2010
We examine the prospects for the detection of Higgs mediated lepton flavor violation at LHC and at a photon collider in the minimal supersymmetric standard model with large lepton flavor violating mass insertions in the $\mu-\tau$ sector constraining the

One-loop mass shift formula for kinks and self-dual vortices [PDF]

, 2005
A formula is derived that allows us to compute one-loop mass shifts for kinks and self-dual Abrikosov-Nielsen-Olesen vortices. The procedure is based in canonical quantization and heat kernel/zeta function regularization methods.Comment: LaTex file, 8 ...

Experimental and Numerical Study of Locking of Low-Frequency Fluctuations of a Semiconductor Laser with Optical Feedback

Photonics, 2022
We study the output of a semiconductor laser with optical feedback operated in the low-frequency fluctuations (LFFs) regime and subject to weak sinusoidal current modulation.

Dual regimes of ion migration in high repetition rate femtosecond laser inscribed waveguides [PDF]

, 2015
Ion migration in high repetition rate femtosecond laser inscribed waveguides is currently being reported in different optical glasses. For the first time we discuss and experimentally demonstrate the presence of two regimes of ion migration found in ...

Current-driven skyrmion motion along disordered magnetic tracks

AIP Advances, 2017
The motion of skyrmions along ferromagnetic strips driven by current pulses is theoretically analyzed by means of micromagnetic simulations. Analytical expressions describing the skyrmion dynamics during and after the current pulse are obtained from an ...

Ferromagnetic/superconducting proximity effect in La0.7Ca0.3MnO3 / YBa2Cu3O7 superlattices [PDF]

, 2003
We study the interplay between magnetism and superconductivity in high quality YBa2Cu3O7 (YBCO) / La0.7Ca0.3MnO3(LCMO)superlattices. We find evidence for the YBCO superconductivity depression in presence of the LCMO layers.

A Borane Sandwich Analogue of Ferrocene

Angewandte Chemie, EarlyView.
The first ferrocene analogue with two boron‐based ligands is identified through a global exploration of the FeB10H20 potential energy surface. The η5,η5‐Fe(B5H10)2 complex emerges as the global minimum, showing that metal coordination inverts borane stability and enables aromatic boron rings inaccessible in isolation.

Influence of particle size in silo discharge

EPJ Web of Conferences, 2017
Recently Janda et al. [Phys. Rev. Lett. 108, 248001 (2012)] reported an experimental study where it was measured the velocity and volume fraction fields of 1 mm diameter stainless steel beads in the exit of a two-dimensional silo.
