Carrollian Dictionary for Massive Particles at Null Infinity
Yu-fan Zheng
Massive particles reach timelike rather than null infinity, leaving their Carrollian boundary description unresolved. We construct a Carrollian dictionary for massive one-particle…
Missing Descendants in the Carrollian Conformal Family
Yu-fan Zheng
In the Carrollian conformal algebra, the relation implies that annihilates all operators generated from a primary by temporal translation . The standard co…
Carrollian holography with agentic AI: Real mass is imaginary
Reiko Liu, Wen-Jie Ma, Hu Zheng +1
We introduce LACIA, a verification-driven agentic AI workflow for theoretical physics, and apply it with independent human checks to construct Carrollian conformal bases. We develo…
Supersymmetric BMS Algebras Revisited: Electric/Magnetic Superalgebras and Free Field Realization
Yu-fan Zheng
In this work, we present a systematic classification of supersymmetric extensions of the BMS algebra and their realizations in free field theories. By requiring that supercharg…
Structure of Carrollian (conformal) superalgebra
Yu-fan Zheng, Bin Chen
In this work, we investigate possible supersymmetric extensions of the Carrollian algebra and the Carrollian conformal algebra in both and . For the super-Carrollian alg…
Quantization of Carrollian conformal scalar theories
Bin Chen, Haowei Sun, Yu-fan Zheng
In this work, we study the quantization of Carrollian conformal scalar theories, including two-dimensional(2D) magnetic scalar and three-dimensional(3D) electric and magnetic scala…
