Majorana Positivity and the Fermion Sign Problem of Quantum Monte Carlo Simulations. [PDF]
Physical Review Letters, 2016 The sign problem is a major obstacle in quantum Monte Carlo simulations for many-body fermion systems. We examine this problem with a new perspective based on the Majorana reflection positivity and Majorana Kramers positivity.

Shallow trimers of two identical fermions and one particle in resonant regimes
SciPost Physics, 2022 We consider two identical fermions interacting in the p-wave channel. Each fermion also interacts with another particle in the vicinity of an s-wave resonance.

Direct observation of how the heavy-fermion state develops in CeCoIn 5 [PDF]
, 2016 Heavy fermion materials gain high electronic masses and expand Fermi surfaces when the high-temperature localized f electrons become itinerant and hybridize with the conduction band at low temperatures.

Spin‐Selective Catalysts for Oxygen‐Involved Electrocatalysis
Advanced Energy and Sustainability Research, EarlyView.The sluggish kinetics of oxygen‐involved electrocatalysis hinders the efficiency of the energy conversion process, which can be promoted by using spin‐polarized materials to conduct spin‐selective electron transfer. This review delivers a thorough and timely overview of state‐of‐the‐art spin‐selective catalysts, aiming to offer a clear route for ...

On the trace anomaly of a Weyl fermion [PDF]
Journal of High Energy Physics, 2016 We calculate the trace anomaly of a Weyl fermion coupled to gravity by using Fujikawa’s method supplemented by a consistent regulator. The latter is constructed out of Pauli-Villars regulating fields.

Large $$N_\mathrm{f}$$ N f for multiple representations
European Physical Journal C: Particles and Fields, 2021 We present an extension of the large- $$N_\mathrm{f}$$ N f formalism that allows one to study cases with multiple fermion representations. The pole structure in the beta function is traced back to the intrinsic non-abelian nature of the gauge group ...

Quantum‐Classical Simulation of Quantum Field Theory by Quantum Circuit Learning
Annalen der Physik, EarlyView.Quantum circuit learning is employed to simulate quantum field theories (QFTs). By integrating a minimal qubit configuration and low‐depth circuits, the approach predicts real‐time dynamics accurately. It effectively simulates complex phenomena such as quench and chiral dynamics in a model of quantum electrodynamics, aligning well with classical ...
