I'm wondering if we just looking at the two sides of the same coin and if there is actually a correlation of DM with DE?
Is it possible that DM just to be a gravitational effect (or an effect that mimics classical gravity) of DE?
Both seem to interact with normal matter in our visible Universe via gravity. Normal gravity for DM and an effective negative gravity for DE (i.e. Cosmological Constant) that leads to the observed accelerated expansion of our Universe?
But isn't possible Dark Energy to have also an effective normal gravitational component (positive gravity) at the same time that we conceive as dark matter gravity?
Maybe the elusive Dark Matter particle (Devil's Particle :) is just the possible hidden Dark Energy particle.

No, dark energy is described by negative energy density. So if GTR is true, friedmann equations will give positive accelerating universe. But dark matter produces negative pulling force like ordinary matter.

There is no any so called "Dark Energy". Galaxies are not acclerating. The velocities of galaxies are still constant. The Velocity is equal to V=Hr While r increases with time then H decreases with time too (H=1/T where T is the age of the Universe) and V=r(t)/T(t)=const. So for a bilion years and more this velocity still will remain the same as before though r will be bigger while H will be lower. The proportionality bytween r and V is not a result of any acceleration bt it is a consequence of the manner of observation of the reality see for instane https://youtu.be/iC3fVsU_XIM.

Gravitation is the flow of ether to the gravitating centers. Call the ether "dark matter" - and calculate the amount of energy you need. The density of the ether (the density of space outside the galactic plane) can be calculated by understanding the essence of "Planck's constant". Publications are available, look in "Проблемы исследования Вселенной" (Problems of the study of the Universe).

Yes, that dark matter is a gravitational impact of dark energy is a good idea, but we first must widen our horizon.
We consider that gravitational fields have a negative energy density. But an absolute negative energy density must not exist. Therefor nature needs dark energy to overcompensate the negative energy density of the gravitational fields everywhere in the universe. This even includes the gravitational field at the surface of the largest neutron stars.
But an absolute homogenous dark energy has no sensible effect. The dark energy then is omnipresent, even in the interior of stars. But there we have a high energetic activity which excites the dark energy. The stars are emitters of incoherent waves of dark energy density. These waves increase the energy density, while gravitational fields decrease the energy density. The gradient of the energy density has gravitational impact. The gradient of the increase has the opposite effect as the gradient of the decrease. Therefor with increasing star activity a bigger part of the gravitational impact of the star matter becomes shielded by the energy density gradient.
The shielding degrades with the same decay factor 1/r² like the gravitational field. We therefor cannot differentiate it from gravity. But there is a difference. The shielding ends if the energy density has decayed to the background density. After the decay the shielded gravitational impact appears.
We then can conclude that the shielded matter is the dark matter.
The Tully Fisher observation that brighter galaxies apparently have more dark matter underlines this hypothesis.
They are both caused by the same thing. See Quasi Steady State Cosmology or the extension of QSSC - the Scalar Theory of Everything.
Yes there is a reasonable theory of how dark matter could attract gravity and have no other interactions. To attract gravity it must be a stress field of potential energy as shown in the LaGrange Density, a scalar with no Poynting vector, with no E components, and with no H components.
On large scale stress energy is observed in curvature. Small scale stress is represented in the change of amplitudes and frequencies of micro oscillators.
Interference patterns of CMB can produce such a scalar potential field, example when two equal photons of CMB collide head on. Poynting vectors extinguish as do all E and H components. When photons are not equal the stress field can still be created but a residual photon of less energy may coexist with the stress field quanta. Interference patterns are well understood and verified in experiments. For CMB to exist and be measured it is virtually guaranteed that a scalar potential stress field must coexist.
A scalar stress quanta may have a long half life and eventually decay into two equal photons of CMB, each having half the energy and traveling in opposite directions. Decay is necessary to avoid complete disappearance of the CMB.
Dark energy is a similar case except two identical microwaves traveling in the same direction combine to add the Poynting vectors while canceling out all the E and H components Unequal photons still can combine and the stress field may coexist with a small residual photon. This is a vector kinetic energy stress field and opposes gravity in the LaGrange Density, but has no other interactions. Quanta may collide occasionally to regenerate the microwaves
In both scalar and vector cases the E components have opposite polarity and attract each other, as do the H components, helping to construct the interference patterns.
For this question two equal quanta of vectored kinetic stress energy, acting like dark energy, can collide head on and produce two quanta of scalar potential stress energy that function like dark matter. For CMB to exist the two fields like dark energy and dark matter are virtually guaranteed to coexist because of the way interference patterns are understood.
Quanta Magazine quoted Chuck Bennett and his Wilkinson Microwave Anisotropy Probe (WMAP) team in early 2003. "The team announced their first results in February 2003. Their map of the “cosmic microwave background” (CMB), which they refined in subsequent years, indicated that the familiar matter of planets, gas and stars makes up just 4.6% of the cosmos, while unseen dark matter comprises 24%. The remaining 71.4% of the cosmic pie chart had to be dark energy, which is thought to infuse the fabric of space itself. The numbers changed only a little when WMAP’s successor, the Planck satellite, took an even sharper image of the CMB 10 years later. And whereas other evidence of dark energy and dark matter continues to be contested, their fingerprints in the CMB have gone virtually unquestioned."
CMB works out to about 0.0033% included in the 4.6% or about 0.26 eV per cubic centimeter, compared to dark energy 560 eV per cubic centimeter.
Most of the energy and matter are in the dark modes, indicating that they are long lasting and were produced mostly long ago from interference patterns of CMB at substantially higher temperatures than CMB has now.. They continue in a slow equilibrium to regenerate CMB and prevent it from disappearing. Anisotropies are a concern but not sufficient to change the explanations, considering the long time scales involved.
Answer yes and with robust science.
Jerry Decker Obviously, you have very special ideas about dark matter. But it is confusing that you are mentioning the CMB. The energy density of the CMB is more than ten orders of magnitude below the expected level of dark energy involved in hiding dark matter.
Maybe this unprecedented article would help your perception

If there is a correlation between DE and DM then it should act antigravitational.
Paul Pistea "If there is a correlation between DE and DM then it should act antigravitational."
Yes dark energy is emitted by accelerated masses. Ergo stars, which contain a huge lot of accelerated masses emit dark energy. This emission leads to a gradient which has antigravitational impact.
This gradient partially shields the gravitational impact of the star mass. It decays like mass induced gravity.
But as soon as it begins to decay below the background density of dark energy, this background energy fills the gap. Then the shielding effect ends and the gravitational influence of the true star mass appears.
This appearance is interpreted as dark matter.
If dark matter is ether with a density of 1/10 x 26, contained in Planck's constant (and it is!), then this is the cause and essence of gravity. There are my works on this topic in RG.
