We analyze the stability of time-reversal (T) and lattice fourfold (C_{4}) symmetry breaking three-dimensional higher-order topological (HOT) Dirac semimetals (DSMs) and the associated one-dimensional hinge modes in the presence of random pointlike charge impurities. Complementary real space numerical and momentum space renormalization group (RG) analyses suggest that a HOTDSM. while ... https://shopredoners.shop/product-category/originals-crewneck-sweater/
