Fermionization of conformal boundary states
Hiromi Ebisu, Masataka Watanabe
We construct the complete set of boundary states of two-dimensional fermionic CFTs using that of the bosonic counterpart. We see that there are two groups of boundary conditions, w…
Quantum Information Theory of the Gravitational Anomaly
Simeon Hellerman, Domenico Orlando, Masataka Watanabe
We show that the standard notion of entanglement is not defined for gravitationally anomalous two-dimensional theories because they do not admit a local tensor factorization of the…
Transition of Large -Charge Operators on a Conformal Manifold
Adar Sharon, Masataka Watanabe
We study the transition between phases at large -charge on a conformal manifold. These phases are characterized by the behaviour of the lowest operator dimension for fi…
S-duality and correlation functions at large R-charge
Simeon Hellerman, Shunsuke Maeda, Domenico Orlando +2
We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in SQCD with four flavors within the framework of the Large Quantum Number E…
Accessing Large Global Charge via the -Expansion
Masataka Watanabe
We compute the lowest operator dimension at large global charge in the Wilson-Fisher model in dimensions, to leading order in both and . The fi…
Page Curves for General Interacting Systems
Hiroyuki Fujita, Yuya O. Nakagawa, Sho Sugiura +1
We calculate in detail the Renyi entanglement entropies of cTPQ states as a function of subsystem volume, filling the details of our prior work [Nature Communications 9, 1635 (2018…
Universal correlation functions in rank 1 SCFTs
Simeon Hellerman, Shunsuke Maeda, Domenico Orlando +2
Carrying to higher precision the large- expansion of Hellerman and Maeda, we calculate to all orders in the power-law corrections to the two-point func…
Operator Dimensions from Moduli
Simeon Hellerman, Shunsuke Maeda, Masataka Watanabe
We consider the operator spectrum of a three-dimensional superconformal field theory with moduli spaces of one complex dimension, such as the fixed point theory with…
A Note on Inhomogeneous Ground States at Large Global Charge
Simeon Hellerman, Nozomu Kobayashi, Shunsuke Maeda +1
In this note we search for the ground state, in infinite volume, of the Wilson-Fisher conformal model, at nonzero values of the two independent charge densities $ρ_{1,…
Universality in volume law entanglement of pure quantum states
Yuya O. Nakagawa, Masataka Watanabe, Hiroyuki Fujita +1
A pure quantum state can fully describe thermal equilibrium as long as one focuses on local observables. Thermodynamic entropy can also be recovered as the entanglement entropy of…
Electronic structure of helicoidal graphene: massless Dirac particles on a curved surface with a screw symmetry
Masataka Watanabe, Hisato Komatsu, Naoto Tsuji +1
Massless Dirac particles on the helicoid are theoretically investigated. With its possible application being helical graphene, we explore how the peculiarities of Dirac particles a…
On the CFT Operator Spectrum at Large Global Charge
Simeon Hellerman, Domenico Orlando, Susanne Reffert +1
We calculate the anomalous dimensions of operators with large global charge in certain strongly coupled conformal field theories in three dimensions, such as the O(2) model and…
