Recent research has reveal the crucial role of quantum entanglement and symmetries in determining the nature of many-body quantum ground states beyond phases with spontaneously broken symmetries. In this talk, I hope to give a general outline of this exciting development and provide a concrete realisation of such a phase – the lattice realization of integer quantum Hall phase in bosons (BIQH). Interestingly, unlike fermions, interactions form a crucial ingredient in stabilizing such a phase. I will also show the exciting connection between the BIQH phase and the Chiral spin liquid phase realised in certain Kagome antiferromagnets, obtained through the concept of ’gauging’ a global symmetry. |
