Squeezed coherent states for gravitational well in noncommutative space

Massless polarized particle and Faraday rotation of light in the Schwarzschild spacetime

“…The dual tensor in curved space is defined as follows: fµν = − det g µν ǫ µνρσ f ρσ , ǫ 0123 = −1. The remaining ambiguity due to e 1 , contained in these equations, is related with reparametrization invariance, and disappears when we take our variables in the coordinate-time parametrization 4 x i (t).…”

“…In general relativity the electromagnetic radiation, taken in the approximation of a massless point particle, propagates along null geodesics. However, in modern applications [1][2][3][4][5][6][7][8][9][10][11][12][13] an actual becomes the task to take into account the polarization degrees of freedom of a light beam. This implies analysis of Maxwell equations in curved spacetime, the task with quite long history, see [14][15][16][17] and the recent review [18].…”

An angular rainbow of light from curved spacetime

“…Description of light rays in a gravitational field beyond the geometrical optics approximation has a long history [1,2], and is widely discussed in the current literature [3][4][5][6][7][8][9][10][11][12][13]. It is expected, that account of polarization and chirality of the light beam could lead to a number of dynamic effects, similar to those that occur for spinning particles in a gravitational field [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. First, influence of spin-orbit interaction on the trajectory is under discussion [3][4][5][6][32][33][34][35], and is considered as a gravitational analogue of Magnus or spin Hall effects of light observed in medium [36].…”
