This 11-minute conference talk presents the Rejection-free Cluster Wang-Landau Algorithm for Hard-core Lattice Gases by Jetin Elsamma Thomas from the International Centre for Theoretical Sciences. Explore an innovative computational approach for studying hard-core lattice gas systems as part of the 10th Indian Statistical Physics Community Meeting. The presentation contributes to the broader discussion of statistical physics topics including mathematical aspects, out-of-equilibrium systems, quantum fluids, disordered systems, biological physics, soft matter, nonlinear physics, and interdisciplinary complex systems. The annual meeting brings together scientists, postdoctoral fellows, and graduate students from across India working in statistical physics, fostering an inclusive environment that encourages participation from underrepresented groups.
