Thou shalt not tunnel: Complex instantons and tunneling suppression in deformed quantum mechanics
Jie Gu, Marcos Marino
The quantization of the Seiberg-Witten curve of super Yang-Mills theory leads to a deformation of one-dimensional quantum mechanics with unconventional behavior. Most…
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…
Spectral Fluctuation-Dissipation-Response Inequalities
Jie Gu
We derive spectral fluctuation--dissipation--response inequalities for finite-state Markov jump processes. By comparing the causal susceptibility to its passive equilibrium referen…
Comment on "Extension of the adiabatic theorem"
Jie Gu
Phys. Rev. B 113, 165102 (2026) proposed the conjecture that, for quantum quenches within the same phase, the overlap between the initial ground state and postquench eigenstates is…
Resurgent properties of -deformed conformal field theories
Jie Gu, Yunfeng Jiang, Huajia Wang
We elaborate on the resurgence analysis on the -deformed 2d conformal field theory (CFT). Writing the deformed partition function as an infinite series in the deform…
Resurgence of -deformed Partition Function
Jie Gu, Yunfeng Jiang, Huajia Wang
We study non-perturbative effects of torus partition function of the -deformed 2d CFTs by resurgence. The deformed partition function can be written as an infinite series…
