The phrase "a theoretical proposal" is correct and usable in written English.
It can be used when discussing an idea or suggestion that is based on theory rather than practical application or empirical evidence.
Example: "The researchers submitted a theoretical proposal for a new model of climate change that could help predict future trends."
Alternatives: "a conceptual suggestion" or "a hypothetical proposal".
He termed it "a theoretical proposal that bears little, if any relationship to what actually happened".
Recently, there was a theoretical proposal of a binary switch based on a symmetric double-well potential landscape that can be controlled by means of magnetostriction5,6.
This work presents a theoretical proposal for a conceptual model of QFD application aiming at minimising the difficulties in its use.
We present a theoretical proposal for a physical implementation of entanglement concentration and purification protocols for two-mode squeezed microwave photons in circuit quantum electrodynamics (QED).
Architects have fantasized about the High Line since at least the early 1980's, when Steven Holl first completed a theoretical proposal to build a "bridge of houses" that straddled the elevated tracks.
For an historical overview and a theoretical proposal centered on mathematics see Borromeo Ferri 2005.
In the paper, Kane put forward a purely theoretical proposal for a scalable quantum computer based on quantum atoms embedded in silicon.
This time I submitted a very theoretical proposal that I was pretty sure would be turned down.
This assumption seems to be in contradiction with a recent theoretical proposal that the formation probability of electride in the Ti N system is rather low (about 3 4%200 since Ti has a high electronegativity making it unfavorable for the electron donation to the lattice.
Experimental data on this issue are not available yet, but this theoretical proposal makes psychopaths a relevant target for future studies employing CDTD tasks.
Another influential theoretical proposal, the synaptic homeostasis hypothesis12, 20, proposes that sleep reflects homeostatic constraints promoting downscaling rather than potentiation of synaptic connections, leading to a dampening or suppression of existing memories12.
