Finite-temperature critical behaviors in 2D long-range quantum Heisenberg model
Abstract The Mermin-Wagner theorem states that spontaneous continuous symmetry breaking is prohibited in systems with short-range interactions at spatial dimension D ≤ 2. For long-range interactions with a power-law form (1/r α ), the theorem further forbids ferromagnetic or antiferromagnetic order...
