From to : High-temperature relations, subleading semi-universality, and conformal anomalies
Arnav Advant, Harsh Anand, Nathan Benjamin +6
The free energy of any CFT, , admits two expansions: high temperature () and fast rotation (). We demonstrate that in , local…
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…
Semi-universality of CFT entropy at large spin
Harsh Anand, Nathan Benjamin, Vipul Kumar +4
The thermal partition function, , of a on is parameterized by the inverse temperature along with angular velocities . In this pap…
Universality of the microcanonical entropy at large spin
Sridip Pal, Jiaxin Qiao, Balt C. van Rees
We consider rigorous consequences of modular invariance for two-dimensional unitary non-rational CFTs with . Simple estimates for the torus partition function can lead to re…
Universality of Rényi Entropy in Conformal Field Theory
Yuya Kusuki, Hirosi Ooguri, Sridip Pal
We use the thermal effective theory to prove that, for the vacuum state in any conformal field theory in dimensions, the -th Rényi entropy behaves as $S_A^{(n)}…
Entanglement asymmetry and symmetry defects in boundary conformal field theory
Yuya Kusuki, Sara Murciano, Hirosi Ooguri +1
A state in a quantum system with a given global symmetry, , can be sensitive to the presence of boundaries, which may either preserve or break this symmetry. In this work, we in…
A universal inequality on the unitary 2D CFT partition function
Indranil Dey, Sridip Pal, Jiaxin Qiao
We prove the conjecture proposed by Hartman, Keller and Stoica [HKS14]: the grand-canonical free energy of a unitary 2D CFT with a sparse spectrum below the scaling dimension $\fra…
Angular fractals in thermal QFT
Nathan Benjamin, Jaeha Lee, Sridip Pal +2
We show that thermal effective field theory controls the long-distance expansion of the partition function of a -dimensional QFT, with an insertion of any finite-order spatial i…
