Norms, overlaps and Yangian descendants for the Haldane-Shastry spin chain
Yunfeng Jiang, Jules Lamers, Yuan Miao
The Haldane-Shastry spin chain is a prototypical integrable model with long-range interactions, notable for hosting quasiparticles with fractional statistics and serving as a discr…
Gate Parameter Lee-Yang Zeros and Dynamical Phases in Quantum Circuits
Chang Liu, Yu Wu, Yunfeng Jiang +1
We propose gate-parameter Lee-Yang zeros of Loschmidt amplitudes as probes of dynamical phases in finite quantum circuits. We illustrate this approach using a brickwork model, wher…
Fusion of Integrable Defects and the Defect -Function
Yang He, Yunfeng Jiang, Yuxiao Liu
We study exact defect -functions for integrable line defects in two-dimensional integrable quantum field theory and use them to probe defect fusion. We consider three settings:…
Enumerative Geometry on KSBA moduli spaces
Yunfeng Jiang
We survey two new compactification methods for the KSBA moduli space of general type surfaces so that both of them admit a perfect obstruction theory. Virtual fundamental classes e…
Beyond Hagedorn: A Harmonic Approach to -deformation
Jie Gu, Jue Hou, Yunfeng Jiang
We apply harmonic analysis to study the -deformed torus partition function. We first express the CFT partition functions in terms of Maass waveforms, including the Eisens…
Giant Graviton Correlators as Defect Systems
Junding Chen, Yunfeng Jiang, Xinan Zhou
We consider correlation functions of two maximal giant gravitons and two light -BPS operators in 4d SYM. Viewed as two-point correlators in the presenc…
