Controlled Phase Shifts with a Single Quantum Dot [PDF]
Science, 2008 Optical nonlinearities enable photon-photon interaction and lie at the heart of several proposals for quantum information processing, quantum nondemolition measurements of photons, and optical signal processing. To date, the largest nonlinearities have been realized with single atoms and atomic ensembles.

Harmonically-related diffraction gratings-based interferometer for quadrature phase measurements [PDF]
, 2006 We demonstrate the use of shallow diffraction gratings for quadrature phase interferometry. A single shallow diffraction grating-based Michelson interferometer yields only trivial (0° or 180°) phase shift between different output ports.

Comprehensive steady state analysis of bidirectional dual active bridge DC/DC converter using triple phase shift control [PDF]
, 2014 Several papers have been published recently on TPS control of dual active bridge (DAB) converter, however, no complete study of the converter operation behaviour exists, that takes into account all switching modes in both charging and discharging ...

Multi-Objective Unified Optimal Control Strategy for DAB Converters with Triple-Phase-Shift Control
Energies, 2021 To solve the problems of large current stress, difficult soft-switching of all switches, and slow dynamic response of dual active bridge converters, a multi-objective unified optimal control strategy based on triple-phase-shift control was proposed.

Total control over ultracold interactions via electric and magnetic fields [PDF]
, 2007 The scattering length is commonly used to characterize the strength of ultracold atomic interactions, since it is the leading parameter in the low-energy expansion of the scattering phase shift.

Robust interferometer with external phase-shift control
Optics Express, 2017 We describe a robust interferometer with external phase-shift control that does not require moving parts. The optical architecture resembles a common-path device in which the interfering waves propagate together in one collimated beam passing through the test sample.

Experimental Demonstration of π Equivalent Phase-Shifted SBG Laser With Controlled Distributed Phase Shift [PDF]
IEEE Photonics Journal, 2019 We designed and fabricated a π equivalent phase-shifted sampled Bragg grating (SBG) semiconductor laser with a controlled distributed phase shift. The phase shift is equivalently realized with reconstruction-equivalent-chirp (REC) technique. The laser is divided into three sections with the same length. By injecting different currents into the side and

Enhancement of entanglement transfer in a spin chain by phase shift-control [PDF]
, 2006 We study the effect of a phase shift on the amount of transferrable two-spin entanglement in a spin chain. We consider a ferromagnetic Heisenberg/XY spin chain, both numerically and analytically, and two mechanisms to generate a phase shift, the Aharonov-
