Vortex-enhanced photovoltaic current in disordered topological materials
Pavlo Sukhachov, Penghao Zhu, Ella Banyas +2
In disordered topological materials, real-space crystalline defects interplay with momentum-space wave function singularities to \textit{enhance} the bulk photovoltaic current. Wha…
General Conditions for Axis Dependent Conduction Polarity
Poulomi Chakraborty, Brian Skinner, Penghao Zhu
Axis-Dependent Conduction Polarity (ADCP) refers to the phenomenon in which electrical transport within a single material is p-type along one crystallographic direction and n-type…
Giant non-reciprocity and gyration through modulation-induced Hatano-Nelson coupling in integrated photonics
Ogulcan E. Orsel, Jiho Noh, Penghao Zhu +4
Asymmetric energy exchange interactions, also known as Hatano-Nelson type couplings, enable the study of non-Hermitian physics and associated phenomena like the non-Hermitian skin…
Stripe charge order driven manipulation of Majorana bound states in 2M-WS2 topological superconductor
Xuemin Fan, Xiaoqi Sun, Penghao Zhu +8
Majorana bound states (MBSs) are building blocks for topological quantum computing. They can be generated via the combination of electronic topology and superconductivity. To achie…
Delicate Topology of Luttinger Semimetal
Penghao Zhu, Rui-Xing Zhang
Recent advances in delicate topology have expanded the classification of topological bands, but its presence in solid-state materials remains elusive. Here we show that delicate to…
Anomalous shift and optical vorticity in the steady photovoltaic current
Penghao Zhu, A. Alexandradinata
Steady illumination of a non-centrosymmetric semiconductor results in a bulk photovoltaic current, which is contributed by real-space displacements (`shifts') of charged quasiparti…
