Designing Efficient Metal Contacts to Two-Dimensional Semiconductors MoSiN and WSiN Monolayers
Qianqian Wang, Liemao Cao, Shi-Jun Liang +8
Metal contacts to two-dimensional (2D) semiconductors are ubiquitous in modern electronic and optoelectronic devices. Such contacts are, however, often plagued by strong Fermi leve…
Topological defect engineering and PT-symmetry in non-Hermitian electrical circuits
Alexander Stegmaier, Stefan Imhof, Tobias Helbig +14
We employ electric circuit networks to study topological states of matter in non-Hermitian systems enriched by parity-time symmetry and chiral symmetry anti-$\mathca…
Anisotropic non-linear optical response of nodal loop materials
Tommy Tai, Ching Hua Lee
Nodal line semimetals have lately aroused much experimental and theoretical interest, with their gap closing along unconventional trajectories in the 3D Brillouin zone. These traje…
Ultrafast and Anharmonic Rabi Oscillations between Non-Bloch-Bands
Ching Hua Lee, Stefano Longhi
Rabi flopping between Bloch bands induced by a weak ac resonant field is a coherent effect involving interband transitions. Here we consider the fundamental processes of emission/a…
