Physical observables from boundary artifacts: scalar glueball in Yang-Mills theory
Abhishek Chowdhury, A. Harindranath, Jyotirmoy Maiti
By relating the functional averages of a generic scalar operator in simulations with Open (O) and Periodic (P) boundary conditions (BCs) respectively for lattice gauge theo…
Correlation and localization properties of topological charge density and the pseudoscalar glueball mass in SU(3) lattice Yang-Mills theory
Abhishek Chowdhury, A. Harindranath, Jyotirmoy Maiti
Towards the goal of extracting the continuum properties, we have studied the Topological Charge Density Correlator (TCDC) and the Inverse Participation Ratio (IPR) for the topologi…
Open Boundary Condition, Wilson Flow and the Scalar Glueball Mass
Abhishek Chowdhury, A. Harindranath, Jyotirmoy Maiti
A major problem with periodic boundary condition on the gauge fields used in current lattice gauge theory simulations is the trapping of topological charge in a particular sector a…

Abhishek Chowdhury, A. Harindranath, Jyotirmoy Maiti +1
We find that using open boundary condition in the temporal direction can yield the expected value of the topological susceptibility in lattice SU(3) Yang-Mills theory. As a further…
