Sign-problem-resilient singular-value probe in determinant quantum Monte Carlo
Wen Chen, Rubem Mondaini
The sign problem limits determinant quantum Monte Carlo studies of strongly correlated fermion systems. In the spin-channel Hubbard-Stratonovich decoupling, spin correlations are e…
Spacelike-Collinear Scattering by the Method of Regions
Wen Chen, Einan Gardi, Rourou Ma +3
We study the spacelike-collinear limit of gauge-theory scattering amplitudes using the Method of Regions. The corresponding splitting amplitude violates strict collinear factorisat…
Unveiling quantum criticality of disordered Aubry-André-Harper models via typical fidelity susceptibility
Tian-Cheng Yi, Ying-Ying Fang, Wen Chen +2
In this study, we investigate the localization transition and quantum criticality {in the ground state of the} disordered Aubry-André-Harper (AAH) model, where a quasiperiodic pote…
An Improvement of AmpRed: Analytic Continuation of Complex Integrals
Wen Chen
The AmpRed package has been updated with an improved method for analytic continuation of complex integrals. Compared to the previous version, the new implementation significantly e…
Semi-automatic Calculations of Multi-loop Feynman Amplitudes with AmpRed
Wen Chen
We present a Mathematica package AmpRed for the semi-automatic calculations of multi-loop Feynman amplitudes with high efficiency and precision. AmpRed implements the methods of in…
Unregulated Divergences of Feynman Integrals
Wen Chen
Feynman integrals can be expanded asymptotically with respect to some small parameters at the integrand level, a technique known as the expansion by regions. A naive expansion by r…
Multifractality and pre-thermalization in the quasi-periodically kicked Aubry-André-Harper model
Wen Chen, Pedro D. Sacramento, Rubem Mondaini
In a class of periodically driven systems, multifractal states in non-equilibrium conditions and robustness of dynamical localization when the driving is made aperiodic have receiv…
Linear-scale simulations of quench dynamics
Niaz Ali Khan, Wen Chen, Munsif Jan +1
The accurate description and robust computational modeling of the nonequilibrium properties of quantum systems remain a challenge in condensed matter physics. In this work, we deve…
Soft Theorem to Three Loops in QCD and Super Yang-Mills Theory
Wen Chen, Ming-xing Luo, Tong-Zhi Yang +1
The soft theorem states that scattering amplitude in gauge theory with a soft gauge-boson emission can be factorized into a hard scattering amplitude and a soft factor. In this pap…
A Representation Transformation of Parametric Feynman Integrals
Wen Chen
A transformation on homogeneous polynomials is proposed, which is further applied to parametric Feynman integrals. The two representations related through this transformation are d…
Reduction of Feynman Integrals in the Parametric Representation II: Reduction of Tensor Integrals
Wen Chen
In a recent paper by the author (Chen in JHEP 02:115, 2020), the reduction of Feynman integrals in the parametric representation was considered. Tensor integrals were directly para…
