Adiabatic elimination for open quantum systems with effective Lindblad master equations [PDF]
, 2016 We consider an open quantum system described by a Lindblad-type master equation with two times-scales. The fast time-scale is strongly dissipative and drives the system towards a low-dimensional decoherence-free space.

Single-phase harmonic elimination PWM
Electronics Letters, 2000 A new pulsewidth modulation (PWM) strategy is presented for single-phase inverters which closely approximates in 'real-time' the switching angles of harmonic elimination PWM. The new development is based on the well-known conventional regular-sampled technique and does not require any of the intensive offline computations normally associated with ...

Convergence and adiabatic elimination for a driven dissipative quantum harmonic oscillator [PDF]
, 2015 We prove that a harmonic oscillator driven by Lindblad dynamics where the typical drive and loss channels are two-photon processes instead of single-photon ones, converges to a protected subspace spanned by two coherent states of opposite amplitude.

Analysis and elimination of hysteresis and noisy precursors in power amplifiers [PDF]
, 2006 Power amplifiers (PAs) often exhibit instabilities leading to frequency division by two or oscillations at incommensurate frequencies. This undesired behavior can be detected through a large-signal stability analysis of the solution.
