Tunable second harmornic in altermagnetic Josephson junctions
Hai-Peng Sun, Song-Bo Zhang, Chang-An Li +1
We study the influence of external electric and Zeeman fields on the Josephson effect in a planar superconductor/altermagnet/superconductor junction. Remarkably, we find that the c…
Non-Hermitian Mott Skin Effect
Tsuneya Yoshida, Song-Bo Zhang, Titus Neupert +1
We propose a novel type of skin effects in non-Hermitian quantum many-body systems which we dub a non-Hermitian Mott skin effect. This phenomenon is induced by the interplay betwee…
Klein-bottle quadrupole insulators and Dirac semimetals
Chang-An Li, Junsong Sun, Song-Bo Zhang +2
The Benalcazar-Bernevig-Hughes (BBH) quadrupole insulator model is a cornerstone model for higher-order topological phases. It requires π-flux threading through each plaquette of t…
Nonlinear planar magnetotransport due to tilted Dirac cones in topological materials
Arya Thenapparambil, Graciely Elias dos Santos, Chang-An Li +7
Nonlinear planar magnetotransport is ubiquitous in topological HgTe structures, both in tensile (topological insulator) or compressively strained layers (Weyl semimetal phase). We…
Super-resonant transport of topological surface states subjected to in-plane magnetic fields
Song-Bo Zhang, Chang-An Li, Francisco Peña-Benitez +4
Magnetic oscillations of Dirac surface states of topological insulators are expected to be associated with the formation of Landau levels or the Aharonov-Bohm effect. We instead st…
Higher-order Fabry-Pérot Interferometer from Topological Hinge States
Chang-An Li, Song-Bo Zhang, Jian Li +1
We propose an intrinsic 3D Fabry-Pérot type interferometer, coined "higher-order interferometer", that utilizes the chiral hinge states of second-order topological insulators and c…
