Constrained Variational Inference via Safe Particle Flow
Yinzhuang Yi, Jorge Cortés, Nikolay Atanasov
We propose a control barrier function (CBF) formulation for enforcing equality and inequality constraints in variational inference. The key idea is to define a barrier functional o…
Polarized Emission of Intrabinary Shocks in Spider Pulsars from Global 3D Kinetic Simulations
Andrew G. Sullivan, Jorge Cortés, Lorenzo Sironi
In spider pulsar systems, a relativistic intrabinary shock forms when the pulsar wind collides with the massive outflow driven off the pulsar's low-mass stellar companion. The shoc…
Stability Constrained Voltage Control in Distribution Grids with Arbitrary Communication Infrastructure
Zhenyi Yuan, Jie Feng, Yuanyuan Shi +1
We consider the problem of designing learning-based reactive power controllers that perform voltage regulation in distribution grids while ensuring closed-loop system stability. In…
Certifying Stability of Reinforcement Learning Policies using Generalized Lyapunov Functions
Kehan Long, Jorge Cortés, Nikolay Atanasov
Establishing stability certificates for closed-loop systems under reinforcement learning (RL) policies is essential to move beyond empirical performance and offer guarantees of sys…
Variational Formulation of Particle Flow
Yinzhuang Yi, Jorge Cortés, Nikolay Atanasov
This paper provides a formulation of the log-homotopy particle flow from the perspective of variational inference. We show that the transient density used to derive the particle fl…
Particle Acceleration and Nonthermal Emission at the Intrabinary Shock of Spider Pulsars. II: Fast-Cooling Simulations
Jorge Cortés, Lorenzo Sironi
Spider pulsars are binary systems composed of a millisecond pulsar and a low-mass companion. Their X-ray emission, varying with orbital phase, originates from synchrotron radiation…
Particle Acceleration and Nonthermal Emission at the Intrabinary Shock of Spider Pulsars. I: Non-Radiative Simulations
Jorge Cortés, Lorenzo Sironi
Spider pulsars are compact binary systems composed of a millisecond pulsar and a low-mass companion. Their X-ray emission - modulated on the orbital period - is interpreted as sync…
