We show that it is possible to simulate an anyon by a trapped atom which possesses an induced electric dipole moment in the background of electric and magnetic fields in a specific configuration. The electric and magnetic fields we applied contain a magnetic and two electric fields. We find that when the atom is cooled down to the limit of the negligibly small kinetic energy, the atom behaves like an anyon because its angular momentum takes fractional values. The fractional part of the angular momentum is determined by both the magnetic and one of the electric fields. Roles electric and magnetic fields played are analyzed.We show that it is possible to simulate an anyon by a trapped atom which possesses an induced electric dipole moment in the background of electric and magnetic fields in a specific configuration.

Antihydrogen atom in external electric and magnetic fields

Leonti N Labzowsky, V. Sharipov

A theoretical comparison of the behavior of the antihydrogen $(\overline{\mathrm{H}})$ and hydrogen $(\mathrm{H})$ atoms in external electric and magnetic fields is made. It is shown that observable differences arise in the spectroscopic properties of $\mathrm{H}$ and $\overline{\mathrm{H}}$ atoms in parallel electric and magnetic fields of the order of 475 V∕cm and 0.12 T, respectively.A theoretical comparison of the behavior of the antihydrogen $(\overline{\mathrm{H}})$ and hydrogen $(\mathrm{H})$ atoms in external electric and magnetic fields is made.

In-Situ Measurement of Electrical-Heating-Induced Magnetic Field for an Atomic Magnetometer

Jixi Lu, Jing Wang, Ke Yang +4 more

Electrical heating elements, which are widely used to heat the vapor cell of ultrasensitive atomic magnetometers, inevitably produce a magnetic field interference. In this paper, we propose a novel measurement method of the amplitude of electrical-heating-induced magnetic field for an atomic magnetometer. In contrast to conventional methods, this method can be implemented in the atomic magnetometer itself without the need for extra magnetometers. It can distinguish between different sources of magnetic fields sensed by the atomic magnetometer, and measure the three-axis components of the magnetic field generated by the electrical heater and the temperature sensor. The experimental results demonstrate that the measurement uncertainty of the heater’s magnetic field is less than 0.2 nT along the x-axis, 1.0 nT along the y-axis, and 0.4 nT along the z-axis. The measurement uncertainty of the temperature sensor’s magnetic field is less than 0.02 nT along all three axes. This method has the advantage of measuring the in-situ magnetic field, so it is especially suitable for miniaturized and chip-scale atomic magnetometers, where the cell is extremely small and in close proximity to the heater and the temperature sensor.Electrical heating elements, which are widely used to heat the vapor cell of ultrasensitive atomic magnetometers, inevitably produce a magnetic field interference.
