| 3 | Quantum Phases of SrCu2(BO3)2 from High-Pressure Thermodynamics显示文摘In recent years,theoretical proposals for exotic states in quantum magnets are developing very rapidly,but many of these intriguing quantum phases and transitions have been difficult to realize experimentally.One class of such states is the valence bond solid,in which spins entangle locally and form symmetry-breaking singlet patterns.Signatures of a state with four-spin singlets were recently detected in the two-dimensional(2D)quantum magnet SrCu2(BO3)2 under high pressure. | SUN Liling Anders Sandvik | 2020 | Bulletin of the Chinese Academy of Sciences2020，34，2： | 0 |
| 4 | Typicality at quantum-critical points显示文摘We discuss the concept of typicality of quantum states at quantum-critical points, using projector Monte Carlo simulations of an S = 1/2 bilayer Heisenberg antiferromagnet as an illustration. With the projection(imaginary) time τ scaled as τ = a Lz, L being the system length and z the dynamic critical exponent(which takes the value z = 1 in the bilayer model studied here), a critical point can be identified which asymptotically flows to the correct location and universality class with increasing L, independently of the prefactor a and the initial state. Varying the proportionality factor a and the initial state only changes the cross-over behavior into the asymptotic large-L behavior. In some cases, choosing an optimal factor a may also lead to the vanishing of the leading finite-size corrections. The observation of typicality can be used to speed up simulations of quantum criticality, not only within the Monte Carlo approach but also with other numerical methods where imaginary-time evolution is employed, e.g., tensor network states, as it is not necessary to evolve fully to the ground state but only for sufficiently long times to reach the typicality regime. | 刘录 Anders W Sandvik 郭文安 | 2018 | Chinese Physics B2018，27，8： | 0 |
