Decoding conformal field theories: from supervised to unsupervised learning
En-Jui Kuo, Alireza Seif, Rex Lundgren +2
We use machine learning to classify rational two-dimensional conformal field theories. We first use the energy spectra of these minimal models to train a supervised learning algori…
Torus Spectroscopy of the Gross-Neveu-Yukawa Quantum Field Theory: Free Dirac versus Chiral Ising Fixed Point
Michael Schuler, Stephan Hesselmann, Seth Whitsitt +3
We establish the universal torus low-energy spectra at the free Dirac fixed point and at the strongly coupled chiral Ising fixed point and their subtle crossover behaviour in the G…
Quantum field theory for the chiral clock transition in one spatial dimension
Seth Whitsitt, Rhine Samajdar, Subir Sachdev
We describe the quantum phase transition in the -state chiral clock model in spatial dimension . With couplings chosen to preserve time-reversal and spatial inversion symme…
Spectrum of the Wilson-Fisher conformal field theory on the torus
Seth Whitsitt, Michael Schuler, Louis-Paul Henry +2
We study the finite-size spectrum of the O() symmetric Wilson-Fisher conformal field theory (CFT) on the spatial-dimension torus using the expansion in . This is do…
Entanglement entropy of the large Wilson-Fisher conformal field theory
Seth Whitsitt, William Witczak-Krempa, Subir Sachdev
We compute the entanglement entropy of the Wilson-Fisher conformal field theory (CFT) in 2+1 dimensions with O() symmetry in the limit of large for general entanglement geom…
Transition from the spin liquid to antiferromagnetic order: spectrum on the torus
Seth Whitsitt, Subir Sachdev
We describe the finite-size spectrum in the vicinity of the quantum critical point between a spin liquid and a coplanar antiferromagnet on the torus. We obtain the u…
Universal Signatures of Quantum Critical Points from Finite-Size Torus Spectra: A Window into the Operator Content of Higher-Dimensional Conformal Field Theories
Michael Schuler, Seth Whitsitt, Louis-Paul Henry +2
The low-energy spectra of many body systems on a torus, of finite size , are well understood in magnetically ordered and gapped topological phases. However, the spectra at quant…
Exact Chiral Spin Liquids and Mean-Field Perturbations of Gamma Matrix Models on the Ruby Lattice
Seth Whitsitt, Victor Chua, Gregory A. Fiete
We theoretically study an exactly solvable Gamma matrix generalization of the Kitaev spin model on the ruby lattice, which is a honeycomb lattice with "expanded" vertices and links…
