But we know that just from the properties of topological spaces; you aren't proving anything about the subspace topology. I'm not really sure what is happening in your attempt to be honest. But I feel like it is much simpler than you might think, especially if you take the hint into account.

But I think it's more clear the way i wrote it. So I did mention open sets. Otherwise you might not really be able to do any exercises since these basic concepts are really important to understand.

This is an example of how topological properties can be influenced by discrete symmetries. We just saw that time-reversal symmetry can forbid the topological invariant to take a certain set of values. We now study another case where a symmetry changes the topological properties dramatically.

This situation arises naturally when the lattice has two sublattices, as in the hexagonal carbon lattice of graphene. A symmetric spectrum is the consequence of sublattice symmetry. What does this mean for the topological classification? Indeed, we can deform all the Hamiltonians with sublattice symmetry into one another without closing the gap. This means that an extra symmetry may render topological classification trivial. There is another symmetry that has a strong influence on topology: particle-hole symmetry.

It shows up in superconducting systems. As an example, imagine bringing our quantum dot in contact with a superconductor, like this:. A superconductor will create and annihilate pairs of electrons by breaking apart Cooper pairs and forming them.

This results in a Hamiltonian:. The Bogoliubov-de Gennes Hamiltonian acts on wave functions whose first half is composed out of annihilation operators of electrons, and the second half out of creations operators of the same electrons. We can think of them as annihilation operators of an extra set of holes, so that we double the amount of degrees of freedom in the system. We have that:. Particle-hole symmetry is represented by an anti-unitary operator which anti-commutes with the Hamiltonian compare this situation with that of time-reversal and sublattice symmetries.

We can now see what happens when we deform it into a second one. You can however notice that, unlike in the case of sublattice symmetry, energy levels do not repel around zero energy, so that crossings at zero energy appear. At first, they might look a bit mysterious. In general a crossing between energy levels happens in the presence of a conserved quantity, and our random Bogoliubov-de Gennes Hamiltonian does not seem to have an obvious one.

In other words, forming and breaking Cooper pairs does not affect whether the superconducting quantum dots contains an even or odd number of electrons. In short, fermion parity is a conserved quantity provided that isolated electrons do not enter or leave the dot, a possibility which we will disregard.

The above observation reveals that the existence of crossings is due to the fermion parity conservation. Fermion parity, however, is a many-body quantity, which cannot be directly described in terms of the single particle picture of the Bogoliubov-de Gennes Hamiltonian. To understand the existence of the crossings, recall that to obtain a Bogoliubov-de Gennes description of the superconductor we had to double the number of degrees of freedom by introducing holes.

In other words, at each crossing the fermion parity in the ground state of the dot changes from even to odd, or vice versa. Hence these crossings are fermion parity switches. Since the ground state fermion parity is preserved by the superconducting Hamiltonian if there are no Bogoliubov quasiparticles crossing zero energy, the ground state fermion parity is the topological invariant of this system.

It is clear however that this invariant is of a different nature than the one of the non-superconducting systems, which is given by the number of negative eigenvalues of the Hamiltonian. The latter cannot change for a Bogoliubov-de Gennes Hamiltonian, which has a symmetric energy spectrum, and hence it is not suitable to describe changes in fermion parity.

Is there a way to compute this new invariant directly from the Bogoliubov-de Gennes Hamiltonian? In order to introduce the new invariant, we have to start with a basis transformation, that makes the Hamiltonian an antisymmetric matrix. We use the following unitary transformation in particle-hole space,. There is a special number that we can compute for antisymmetric matrices, the Pfaffian. Its rigorous definition is not important for our course.

The basic idea is simple: The eigenvalues of antisymmetric matrices always come in pairs. This feature of the Pfaffian really makes it what we are looking for. Whenever we need to compute a Pfaffian we just use the Pfapack package that calculates Pfaffians for numerical matrices. This means that it is the correct expression for the ground state fermion parity and for the topological invariant.

Topology in condensed matter: tying quantum knots. OK, let's see what we have so far. Which symmetry certainly does not restrict the values that the topological invariant can take? Spinless time-reversal symmetry Sublattice symmetry Conservation law Spinful time-reversal symmetry Show answer The correct answer is: Spinless time-reversal symmetry We cannot be sure about the conservation law, since the blocks may have different remaining symmetries. And we just saw that sublattice symmetry makes every system trivial, while spinful time-reversal makes the numbers of levels even.

As an example, imagine bringing our quantum dot in contact with a superconductor, like this: A superconductor will create and annihilate pairs of electrons by breaking apart Cooper pairs and forming them. The Pfaffian invariant still captures all of the topological properties. Hitesh Shetty. Hitesh Shetty Hitesh Shetty 3 4 4 bronze badges. You have not shown every countable union of A's is open.
