QNMs of slowly rotating Einstein–Bumblebee black hole

European Physical Journal C: Particles and Fields, 2023
We have studied the quasinormal modes (QNMs) of a slowly rotating black hole with Lorentz-violating parameter in Einstein–Bumblebee gravity. We analyse the slow rotation approximation of the rotating black hole in the Einstein–Bumblebee gravity, and ...

A quantum controlled quantum eraser [PDF]

Physica Scripta, 2018
We show that the protocol known as quantum state separation can be used to transfer information between the phase and path of a particle in an interferometer. When applied to a quantum eraser, this allows us to erase some, but not all, of the path information. We can control how much path information we wish to erase.

Quantum processors and controllers [PDF]

2003 IEEE International Workshop on Workload Characterization (IEEE Cat. No.03EX775), 2004
In this paper is presented an abstract theory of quantum processors and controllers, special kind of quantum computational network defined on a composite quantum system with two parts: the controlling and controlled subsystems. Such approach formally differs from consideration of quantum control as some external influence on a system using some set of ...

Chaotic motion of scalar particle coupling to Chern–Simons invariant in the stationary axisymmetric Einstein–Maxwell dilaton black hole spacetime

European Physical Journal C: Particles and Fields, 2023
We investigate the motion of a test scalar particle coupling to the Chern–Simons (CS) invariant in the background of a stationary axisymmetric black hole in the Einstein–Maxwell–Dilaton–Axion (EMDA) gravity.

Positive and Negative Photoconductivity Conversion Induced by H2O Molecule Adsorption in WO3 Nanowire

Nanoscale Research Letters, 2019
Negative photoconductivity effect has been observed in the Au/WO3 nanowire/Au devices in a high humidity environment, which might be attributed to the accumulation of H+ ions on the surface of WO3 nanowire.

Holographic superconductors in 4D Einstein-Gauss-Bonnet gravity

Journal of High Energy Physics, 2020
We investigate the neutral AdS black-hole solution in the consistent D → 4 Einstein-Gauss-Bonnet gravity proposed in [K. Aoki, M.A. Gorji, and S. Mukohyama, Phys. Lett.

Coherent control of quasi-degenerate stationary-like states via multiple resonances

Scientific Reports, 2017
We use three bosons held in a depth-tilt combined-modulated double-well to study coherent control of quantum transitions between quasi-degenerate stationary-like states (QDSLSs) with the same quasienergy.

Effective metric of spinless binaries with radiation-reaction effect up to fourth post-Minkowskian order in effective-one-body theory

European Physical Journal C: Particles and Fields, 2023
By means of the scattering angles, we obtain an effective metric of spinless binaries with radiation-reaction effects up to fourth post-Minkowskian order, which is the foundation of the effective-one-body theory.

Observation of minimal and maximal speed limits for few and many-body states

Nature Communications
Tracking the time evolution of a quantum state allows one to verify the thermalization rate or the propagation speed of correlations in generic quantum systems.
