Transition from the Z2 spin liquid to antiferromagnetic order: Spectrum on the torus
Whitsitt, Seth Paul; Sachdev, Subir (American Physical Society (APS), 2016)We describe the finite-size spectrum in the vicinity of the quantum critical point between a Z2 spin liquid and a coplanar antiferromagnet on the torus. We obtain the universal evolution of all low-lying states in an ... -
Universal Signatures of Quantum Critical Points from Finite-Size Torus Spectra: A Window into the Operator Content of Higher-Dimensional Conformal Field Theories
Schuler, Michael; Whitsitt, Seth Paul; Henry, Louis-Paul; Sachdev, Subir; Läuchli, Andreas M. (American Physical Society (APS), 2016)The low-energy spectra of many body systems on a torus, of finite size L , are well understood in magnetically ordered and gapped topological phases. However, the spectra at quantum critical points separating such phases ...
