Nambu–Jona-Lasinio model in a parallel electromagnetic field
Physics Letters B, 2018 We explore the features of the UA(1) and chiral symmetry breaking of the Nambu–Jona-Lasinio model without the Kobayashi–Maskawa–'t Hooft determinant term in the presence of a parallel electromagnetic field. We show that the electromagnetic chiral anomaly

Strongly interacting matter under external magnetic fields within nonlocal NJL-type models
EPJ Web of Conferences, 2017 We study the behavior of strongly interacting matter under an external magnetic field in the context of nonlocal Nambu–Jona-Lasinio (NJL) -like models.

Evaluating Model Testing and Model Checking for Finding Requirements Violations in Simulink Models [PDF]
arXiv, 2019 Matlab/Simulink is a development and simulation language that is widely used by the Cyber-Physical System (CPS) industry to model dynamical systems. There are two mainstream approaches to verify CPS Simulink models: model testing that attempts to identify failures in models by executing them for a number of sampled test inputs, and model checking that ...

Emergent inflation from a Nambu–Jona-Lasinio mechanism in gravity with non-dynamical torsion
European Physical Journal C: Particles and Fields, 2019 We discuss how inflation can emerge from a four-fermion interaction induced by torsion. Inflation can arise from coupling torsion to Standard Model fermions, without any need of introducing new scalar particles beyond the Standard Model.

Trust the Model When It Is Confident: Masked Model-based Actor-Critic [PDF]
arXiv, 2020 It is a popular belief that model-based Reinforcement Learning (RL) is more sample efficient than model-free RL, but in practice, it is not always true due to overweighed model errors. In complex and noisy settings, model-based RL tends to have trouble using the model if it does not know when to trust the model.

Melting and freeze-out conditions of hadrons in a thermal medium
EPJ Web of Conferences, 2018 We describe two independent frameworks which provide unambiguous determinations of the deconfinement and the decoupling conditions of a relativistic gas at finite temperature.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field
Advances in High Energy PhysicsWe investigate tensor condensates and chiral condensates in the (2+1)-flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field.
