What, I don't get credit for Sliders?

Okay. In that case, Schrödinger's Cat: The Universe Next Door.

Ahoy there! Cheat!! One at a time, old boy!!! Give others a chance to get their oar in!!!!

I'll get a try with Isaac Asimov's The Gods Themselves.
Don't remember the whole story line, but it's about Earth scientists getting a glimpse in a parallel universe, which turned out to be a sort of energy source for ours (or something of the sorts).

Good point - I hadn't quite noticed that it was the same person several times - I'm going to disallow both of these until someone else has had a go.

And as if by magic another appears...

That definitely qualifies. One to go!

You get it back - doubled - in Purgatory, when you have to re-watch everything you wish you'd never watched in the first place.

The topic being "parallel universes", preferably with interaction between universes.

Charlie Stross's "Merchant Princes" series, which starts with an uncertain number of parallel universes, in one of which a family discover they have a recessive mutation that allows them, with certain stimuli, to travel to a parallel universe, along with anything they're in electrical contact with. Except the ground.
They then set up to freight "high value" goods (mostly white and powdery) from one location in the target universe ("ours", "-ish"), through their mediaeval society universe, to another location ; and then back to the corresponding location in the target universe, where white powdery goods have a high market value.
There is conflict between the "Merchant Prince" clan and the law enforcement (then military) of "Us-verse".

I haven't finished the series myself - I should harass the library - but it gets predictably radioactive in one universe, very police-stateish in two others, and then the question of just how those recessive mutations arose needs to be addressed, And Charlie was commenting as writing about how he'd put something outlandishly improbable into his writing in time to have it turn up in real life as soon as the ink splattered onto the dead tree. To be honest, I'm not sure if Charlie has finished it himself.

OK, that's the fifth one and we have a winner - As I remember it the main series of books is complete, with a second series of two or three set a couple of decades later.

And handing a MBP (for finishing this round with an excellent example) and the chalice to Rockdoctor, I shall beat a hasty retreat...

Eye of newt ... tip of Sullivan's cue ... Interestingness of Davis. Let's try brewing up something really weird. Give me a few minutes to find the aqua regia.

Checking the search box for previous use from my secret stash of topics made the length of this thread rather evident, so I've edited the Subject: line in a rather obvious way. If you don't like it, you know what to do. If you do like it, then someone needs to remember every do often.

My stash has an entry "[*] The Inquisitorial hat is yours. ............. Hats in SF, not including functional ones (i.e. helmets of space suits, environment suits for the chlorine breathers, military uniforms, etc)."
[*] I shall dash The Good Doctor's fedora (?) to the ground immediately and strangle it with a certain scarf - mostly because I still can't cast on enough stitches to knit my own.
[*] I recently saw a passing photo of a StarTrek (recent-ish) character played by Whoopie Goldberg (?) wearing a head-mounted Whoopie cushion (?) and I'll add that to the bonfire of the headpieces. (Is it a uniform? Hard to say.) Other Star Trek hats (because I remember none) are acceptable.
[*] Oh - and no cunning fabric-based origami with towels. Other DNA/ H2G2 hats are acceptable.

If the hat fulfils a story function - saving the hero's life by staunching a wound ; a tinfoil one being used to fool a prison lock ; short out the dilithium crystals ; whatever - that is acceptable ; but the wearer should be wearing (or carrying) it primarily for sartorial or other non-functional reasons. Enough people have been whacked in the face by a motorbike helmet to make spacesuit helmets a bit obvious on the weaponry front.

I think that's clear enough. Over to your recalls.

A more recent incarnation of the Doctor went through a fez-wearing phase, "Because fezzes are cool."

And, the incarnation prior to the scarf-wearing one also wore a fedora-like hat (Panama?) occasionally, but like a gentleman, only when outdoors.

Actually, I think the cricket-loving one who came after the scarf-wearing one also wore the Panama hat sometimes (e.g. in Pyramids of Mars), though I might need to report myself to r/MandelaEffect.

Wait, it's all coming back to me now: the fellow prior to the fellow prior to the scarf-wearing one (the fellow whose adventures were notoriously demagnetized for being black-and-white, and hence useless for re-runs) was the original wearer of the fez.

Indiana Jones and the Kingdom of the Crystal Skull. Indiana's Fedora.

Only went with this one as the rest of the Indiana Jones movies were not exactly Science Fiction in the traditional sense. Even this one pushes the Sci-Fi elements to the end of the movie.

If not acceptable there is another on my possibilities list but that will be saved for another time unless someone gets to it first.

Buck Rogers in the 25th Century !!!

Not Buck himself, of course, but specifically Princess Ardala's unforgettably whacky, Viking-inspired headdress from this notorious scene:
