Entanglement Requires Fluctuations at Conformal Interfaces
Yuya Kusuki, Kosei Suzuyama, Yin Tang
We conjecture that the universal logarithmic coefficient for capacity of entanglement is bounded below by the corresponding entropy coefficient $c_{\mathrm{eff}}…
Complex Conformal Manifolds
Yuma Furuta, Wataru Harada, Yuya Kusuki +1
Complex conformal field theories (CFTs) have recently emerged as essential frameworks for understanding non-Hermitian criticality, weakly first-order phase transitions, and walking…
Emergence of 3D Superconformal Ising Criticality on the Fuzzy Sphere
Yin Tang, Cristian Voinea, Liangdong Hu +2
Supersymmetric conformal field theories (SCFTs) form a unique subset of quantum field theories which provide powerful insights into strongly coupled critical phenomena. Here, we pr…
Boundary Criticality of Complex Conformal Field Theory: A Case Study in the Non-Hermitian 5-State Potts Model
Yin Tang, Qianyu Liu, Qicheng Tang +1
Conformal fields with boundaries give rise to rich critical phenomena that can reveal information about the underlying conformality. While most existing studies focus on Hermitian…
Microscopic study of 3D Potts phase transition via Fuzzy Sphere Regularization
Shuai Yang, Yan-Guang Yue, Yin Tang +3
The Potts model describes interacting spins with different components, which is a direct generalization of the Ising model (). Compared to the existing exact solutions in…
Reclaiming the Lost Conformality in a non-Hermitian Quantum 5-state Potts Model
Yin Tang, Han Ma, Qicheng Tang +2
Conformal symmetry, emerging at critical points, can be lost when renormalization group fixed points collide. Recently, it was proposed that after collisions, real fixed points tra…
Universal entanglement signatures of interface conformal field theories
Qicheng Tang, Zixia Wei, Yin Tang +2
An interface connecting two distinct conformal field theories hosts rich critical behaviors. In this work, we investigate the entanglement properties of such critical interface the…
Non-Hermitian Parent Hamiltonian from Generalized Quantum Covariance Matrix
Yin Tang, W. Zhu
Quantum inverse problem is defined as how to determine a local Hamiltonian from a single eigenstate? This question is valid not only in Hermitian system but also in non-Hermitian s…
A nonparametric test for elliptical distribution based on kernel embedding of probabilities
Yin Tang, Bing Li
Elliptical distribution is a basic assumption underlying many multivariate statistical methods. For example, in sufficient dimension reduction and statistical graphical models, thi…
Thermal Correction to Entanglement Spectrum for Conformal Field Theories
Yin Tang, Qicheng Tang, W. Zhu
We calculate the thermal correction to the entanglement spectrum for separating a single interval of two dimensional conformal field theories. Our derivation is a direct extension…
