Abstract
Sideband asymmetry in cavity optomechanics has been explained by particle creation and annihilation processes, which bestow an amplitude proportional to 'n+1' and 'n' excitations to each of the respective sidebands. We discuss the issues with this as well as other interpretations, such as quantum backaction and noise interference, and show that the asymmetry is due to the optomechanical damping caused by the probe and the cooling lasers instead.
List of changes
page 1:
Removed 1st sentence in the introduction
page 2:
"exegesis originates from proclaiming ex cathedra" -->" interpretation originates from stating"
"consequently prove" -- >" consequently provide evidence for"
removed "With the increase of experimental observations of SA, its quantum nature was deemed true."
"This explanation of SA based on the interference between the noise channels is incorrect due to inconsistencies and invalid approximations, which we discuss in Sec.4." --> "The issues with the explanation of SA based on the
interference between the noise channels are discussed in Sec.4."
page 3:
"and to assert that by definition, measurements follow a particular operator order, does not coerce a detector to measure that specific order. " --> "and theoretical postulates on operator order do not necessarily match with the detection's physical
mechanism."
removed "Theoretical interpretations should be based on the physical situation, instead of the experimental validation being subdued to theoretical postulates. This constitutes a problem for experimental validation, as biased premises have
been the starting point."
"classical formulas is dangerously arbitrary" --> "classical formulas is an ambiguous procedure"
page 9:
"First, Eqs.(41,42) of 14 cannot be correct because the response susceptibilities presented for each noise channel are identical," --> "First, in Eqs.(41,42) of 14 the response susceptibilities presented for each noise channel are identical,"
"it is erroneous to think in terms of interference between different noise channels" --> "explaining SA in terms of interference between different noise channels is misleading because"
"lead to the deceitful impression" --> "give the impression"
page 12:
"flaws" --> "problems"
