ABANDONED. Science fiction book about interdimensional jumping through black holes

[Gustavo]

Hello everyone, I hope you can help me, because I do not even remember the author, it's a science fiction book about inter-dimensional jumping through a miniature black hole in a Jewish concentration camp, it jumps between past and future, and one of the protagonists, a girl, developed a machine that controlled electromagnetic waves that produced effects in sexuality or student interest in a university field.

You can "bump" your thread every month or so. This pushes your thread back to the top of the folder instead of languishing here on page 178 where fewer eyes will see it. Get back in the game! Bump!
You can do this by typing a new comment at the end of the thread, or even by typing the word "bump."
Good luck!
