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}}…
The Role of Completeness in Probing Symmetry Breaking
Yuya Kusuki, Hiroyasu Tajima, Shion Yamashika
Completeness is widely recognized in quantum information as an important property of a family of monotones, because it ensures that no information relevant to state conversion is l…
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…
Continuous Family of Conformal Field Theories and Exactly Marginal Operators
Shota Komatsu, Yuya Kusuki, Marco Meineri +1
Does a conformal manifold imply the existence of exactly marginal operators? We answer this question affirmatively under the assumption that there exists a conformal interface with…
Resource-Theoretic Quantifiers of Weak and Strong Symmetry Breaking: Strong Entanglement Asymmetry and Beyond
Yuya Kusuki, Sridip Pal, Hiroyasu Tajima
Quantifying how much a quantum state breaks a symmetry is essential for characterizing phases, nonequilibrium dynamics, and open-system behavior. For mixed states, however, convent…
