Emergent particle-hole symmetry in spinful bosonic quantum Hall systems

Recently, a reevaluation of particle-hole symmetry in fermionic quantum Hall systems has led to a wealth of new insights about quantum Hall phases and connections between quantum Hall physics and other topological phases as well as high-energy physics. Similar progress may be possible in the bosonic case if such a symmetry exists, unlike the fermionic case such a symmetry is not exact. Here, the authors provide the first evidence for the existence of an emergent bosonic particle-hole symmetry.
