Spectral function and bound states in condensed matter

Why is a symmetric traceless tensor zero when averaged over all directions?

What is the relation between non-local order parameters and topological phases?

Why is the ground state important in condensed matter physics?

Why no proton microscopes? Proton diffraction; or proton scattering experiments? Proton crystallography?

Noninteracting electrons in 2D in presence of a magnetic field and a periodic potential?

$1+1D$ $U(1)$ gauge theory is a quantum mechanical system

How do electrons in metals manage to have zero acceleration in constant $E$ field (as in a DC circuit)?

How is the free energy of Kosterlitz-Thouless transition smooth yet non-analytic?

Is the zero-point energy of helium stronger than other liquids to disfavour freezing?
