  If protons don't decay, iron stars are expected to form via quantum tunneling after $10^{1500}$ years, and they are expected to all have become neutron stars or black holes after $10^{10^{26}}$ to $10^...
  As we know a particle in attractive Dirac delta potential has discontinuity in the derivative of its wavefunction. I have two questions in this regard: Can a second-order differential equation (the ...

  What does theory say about tunnelling and universe expansion?
  Correct me if I'm wrong, my limited understanding of how wave functions work let me assume that they don't "zero out", unless through interferences. I would then imagine that, when a ...

  As it is now known because of Gamow, how alpha decay occurs. We have taught this theory in our class in last week. There we have been introduced with a strange phenomenon happening because of which ...

  Why do we say that quantum tunneling is when a particle passes through a barrier they wouldn't classically have enough energy to overcome?
  If a particle is in an energy eigenstate, then it must also be in a superposition of both outside the barrier and inside the barrier. So, if we measure the particle to be outside the barrier, I wouldn'...

  If we suppose that the universe is spatially infinite and extends more or less homogenously in all directions without end (having similar galaxies, stars etc.), then we can assume that there is a more ...

  This question had me thinking about the related 1D problem of two rectangular potential barriers: The potential is zero everywhere but for the two barriers, where it is $V_0$. As ever I am ...

  As it is well known, the tunnel splitting (which are certain differences between energy levels) is the characteristic of the energy spectrum for the double-well potentials. When we calculate the ...

  In the paper PRL 85(2000), 5042, "Hawking radiation as tunneling", by Parikh and Wilczek, https://arxiv.org/abs/hep-th/9907001, there are some integrals, such as Eqs.(6) and (8). They are ...
