abstract
Motivated by sine-square deformation (SSD) for quantum critical systems in 1+1-dimension, we discuss a Mobius quantization approach to the two-dimensional conformal field theory (CFT), which bridges the conventional radial quantization and the dipolar quantization recently proposed by Ishibashi and Tada. We then find that the continuous Virasoro algebra of the dipolar quantization can be interpreted as a continuum limit of the Virasoro algebra for scaled generators in the SSD limit of the Mobius quantization approach.

Emergent Spatial Structure and Entanglement Localization in Floquet Conformal Field Theory
Under sine-square-deformed Floquet driving of a 1+1D CFT, the heating phase localizes energy and Bell-pair entanglement at two fixed-point peaks, and E scales as the exponential of the entropy.
