Explore domain walls and their junctions in N=1 supersymmetric QCD through this physics seminar presented by Evgenii Levlev from Minnesota University. Delve into the multiplicities and characteristics of BPS domain walls that connect different chiral vacua in SQCD with SU(N) gauge group and varying numbers of fundamental quarks. Learn about two distinct classes of degenerate domain walls: locally distinguishable walls that differ in local experiments, and those with identical local structure differentiated only topologically. Understand how two-wall junctions exist in the first class but not in the second, and discover how the multiplicity of k walls maintains the formula N!/[(N−k)!k!] across different cases. Examine the relationship between quark masses and phase transitions, and explore the evolution of low-energy wall world sheet theory from small to large masses. Investigate the proposed low-energy description of wall junctions, all based on research detailed in paper 2411.16845.
