Ferromagnetic Gyroscopes for Tests of Fundamental Physics
Pavel Fadeev, Chris Timberlake, Tao Wang +6
A ferromagnetic gyroscope (FG) is a ferromagnet whose angular momentum is dominated by electron spin polarization and that will precess under the action of an external torque, such…
Sensitivity of Th nuclear clock transition to variation of the fine-structure constant
Pavel Fadeev, Julian C. Berengut, Victor V. Flambaum
Peik and Tamm [Europhys. Lett. 61, 181 (2003)] proposed a nuclear clock based on the isomeric transition between the ground state and the first excited state of thorium-229. This t…
Gravity Probe Spin: Prospects for measuring general-relativistic precession of intrinsic spin using a ferromagnetic gyroscope
Pavel Fadeev, Tao Wang, Y. B. Band +4
An experimental test at the intersection of quantum physics and general relativity is proposed: measurement of relativistic frame dragging and geodetic precession using intrinsic s…
Time reversal invariance violation in neutron-nucleus scattering
Pavel Fadeev, Victor V. Flambaum
Planning and interpretation of the experiments searching for the time reversal (T) and parity (P) violation in neutron reactions require values of the matrix elements of the T,P-vi…
Revisiting spin-dependent forces mediated by new bosons: Potentials in the coordinate-space representation for macroscopic- and atomic-scale experiments
Pavel Fadeev, Yevgeny V. Stadnik, Filip Ficek +3
The exchange of spin-0 or spin-1 bosons between fermions or spin-polarised macroscopic objects gives rise to various spin-dependent potentials. We derive the coordinate-space non-r…
