Reinforcement learning for path integrals in quantum statistical physics
Timour Ichmoukhamedov, Dries Sels
Machine learning is rapidly finding its way into the field of computational quantum physics. One of the most popular and widely studied approaches in this direction is to use neura…
Cash or Comfort? How LLMs Value Your Inconvenience
Mateusz Cedro, Timour Ichmoukhamedov, Sofie Goethals +3
Large Language Models (LLMs) are increasingly proposed as near-autonomous artificial intelligence (AI) agents capable of making everyday decisions on behalf of humans. Although LLM…
Exploring the generalization of LLM truth directions on conversational formats
Timour Ichmoukhamedov, David Martens
Several recent works argue that LLMs have a universal truth direction where true and false statements are linearly separable in the activation space of the model. It has been demon…
How good is my story? Towards quantitative metrics for evaluating LLM-generated XAI narratives
Timour Ichmoukhamedov, James Hinns, David Martens
A rapidly developing application of LLMs in XAI is to convert quantitative explanations such as SHAP into user-friendly narratives to explain the decisions made by smaller predicti…
General memory kernels and further corrections to the variational path integral approach for the Bogoliubov-Fröhlich Hamiltonian
Timour Ichmoukhamedov, Jacques Tempere
The celebrated variational path integral approach to the polaron problem shows remarkable discrepancies with diagrammatic Monte Carlo for the Bogoliubov-Fröhlich Hamiltonian which…
Path-integral approach to the thermodynamics of bosons with memory: Density and correlation functions
Timour Ichmoukhamedov, Jacques Tempere
Expanding upon previous work, using the path-integral formalism we derive expressions for the one-particle reduced density matrix and the two-point correlation function for a quadr…
Path-integral approach to the thermodynamics of bosons with memory: Partition function and specific heat
Timour Ichmoukhamedov, Jacques Tempere
For a system of bosons that interact through a class of general memory kernels, a recurrence relation for the partition function is derived within the path-integral formalism. This…
Vortices in Fermi gases with spin-dependent rotation potentials
Timour Ichmoukhamedov, Jacques Tempere
The rotation of two-component Fermi gases and the subsequent appearance of vortices have been the subject of numerous experimental and theoretical studies. Recent experimental adva…
Feynman path-integral treatment of the Bose polaron beyond the Fröhlich model
Timour Ichmoukhamedov, Jacques Tempere
An impurity immersed in a Bose-Einstein condensate is no longer accurately described by the Fröhlich Hamiltonian as the coupling between the impurity and the boson bath gets strong…
Radial vortex core oscillations in Bose-Einstein condensates
Nick Verhelst, Timour Ichmoukhamedov, Jacques Tempere
Dilute ultracold quantum gases form an ideal and highly tunable system in which superuidity can be studied. Recently quantum turbulence in Bose-Einstein condensates was reported [P…
