Nonperturbative approach to system-reservoir dynamics in the strong-coupling regime and non-Markovian dynamics
(American Physical Society - APSCollege Park, 2014-09)
We present a method to derive an exact master equation for a bosonic system coupled to a set of other bosonic systems, which plays the role of the reservoir, under the strong-coupling regime, i.e., without resorting to ...
Resistência em fadiga cíclica de instrumentos reciprocantes fabricados com ligas de niquel-titânio submetidas a diferentes tratamentos térmicos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIAS ODONTOLÓGICAS, 2019-09-06)
Objectives: This study aimed to evaluate and compare the resistance in cyclic fatigue of three
types of single file reciprocating systems: WaveOne Gold Primary (25 / 0.07), WA1 file (25 /
0.07) and X1 Blue (25 / 0.06), ...
Path integral approach to the full Dicke model
(Elsevier B.V., 2011-10-01)
The full Dicke model describes a system of N identical two level-atoms coupled to a single mode quantized bosonic field. The model considers rotating and counter-rotating coupling terms between the atoms and the bosonic ...
Rotation, spectral variability, magnetic geometry and magnetosphere of the Of?p star CPD -28° 2561
(Oxford University Press, 2015-03)
We report magnetic and spectroscopic observations and modelling of the Of?p star CPD −28° 2561. Using more than 75 new spectra, we have measured the equivalent width variations and examined the dynamic spectra of photospheric ...
Dual constant-flux energy cascades to both large scales and small scales
(American Institute of Physics, 2017-11)
In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from two-dimensional fluids and wave turbulence ...

The suq(2) algebra in the off-diagonal basis and applications to quantum optics
(2001)
We consider a new exactly solvable nonlinear quantum model as a Hamiltonian defined in terms of the generators of the suq(2) algebra. The corresponding matrix elements of finite rotations (the q-deformed Wigner d functions) ...
