Photoinduced and conductance plateaus in topological insulator-superconductor heterostructures
Han Hoe Yap, Longwen Zhou, Ching Hua Lee +1
The past few years have witnessed increased attention to the quest for Majorana-like excitations in the condensed matter community. As a promising candidate in this race, the one-d…
Entangled multi-component 4D quantum Hall states from photonic crystal defects
Xiao Zhang, Youjian Chen, Yuzhu Wang +4
Recently, there has been a drive towards the realization of topological phases beyond conventional electronic materials, including phases defined in more than three dimensions. We…
Anisotropic Pseudopotential Characterization of Quantum Hall Systems under Tilted Magnetic Field
Bo Yang, Ching Hua Lee, Chi Zhang +1
We analytically derived the effective two-body interaction for a finite thickness quantum Hall system with a harmonic perpendicular confinement and an in-plane magnetic field. The…
Topolectrical circuit realization of topological corner modes
Stefan Imhof, Christian Berger, Florian Bayer +8
Quantized electric quadrupole insulators have recently been proposed as novel quantum states of matter in two spatial dimensions. Gapped otherwise, they can feature zero-dimensiona…
Anharmonic interatomic force constants and thermal conductivity from Grüneisen parameters: an application to graphene
Ching Hua Lee, Chee Kwan Gan
Phonon-mediated thermal conductivity, which is of great technological relevance, fundamentally arises due to anharmonic scattering from interatomic potentials. Despite its prevalen…
Topolectrical circuits
Ching Hua Lee, Stefan Imhof, Christian Berger +5
Invented by Alessandro Volta and Félix Savary in the early 19th century, circuits consisting of resistor, inductor and capacitor (RLC) components are omnipresent in modern technolo…
Superconductivity with broken time reversal symmetry in ion irradiated BaKFeAs single crystals
V. Grinenko, P. Materne, R. Sarkar +7
Over the last years a lot of theoretical and experimental efforts have been made to find states with broken time reversal symmetry (BTRS) in multi-band superconductors. In particul…
Band structure engineering of ideal fractional Chern insulators
Ching Hua Lee, Martin Claassen, Ronny Thomale
As lattice analogs of fractional quantum Hall systems, fractional Chern insulators (FCIs) exhibit enigmatic physical properties resulting from the intricate interplay between singl…
Topological dynamics of gyroscopic and Floquet lattices from Newton's laws
Ching Hua Lee, Guangjie Li, Guliuxin Jin +2
Despite intense interest in realizing topological phases across a variety of electronic, photonic and mechanical platforms, the detailed microscopic origin of topological behavior…
