Imaging nodal knots in momentum space through topolectrical circuits
Ching Hua Lee, Amanda Sutrisno, Tobias Hofmann +7
Knots are intricate structures that cannot be unambiguously distinguished with any single topological invariant. Momentum space knots, in particular, have been elusive due to their…

Topological corner modes in a brick lattice with nonsymmorphic symmetry
Yuhan Liu, Yuzhu Wang, Nai Chao Hu +3
The quest for new realizations of higher-order topological system has garnered much recent attention. In this work, we propose a paradigmatic brick lattice model where corner modes…

Tidal surface states as fingerprints of non-Hermitian nodal knot metals
Xiao Zhang, Guangjie Li, Yuhan Liu +3
Non-Hermitian nodal knot metals (NKMs) contains intricate complex-valued energy bands gives rise to knotted exceptional loops and new topological surface states. We introduce a for…
