Are degenerate groundstates induced by spontaneous symmetry breakings in quantum phase transitions?

Mei He, Qian-Qian Shi, Sam Young Cho

Recently, emergent symmetry is one of fast-growing intriguing issues in many-body systems. Its roles and consequential physics have not been well understood in quantum phase transi…
