Observation of mirror-odd and mirror-even spin texture in ultrathin epitaxially strained RuO2 films
Yichen Zhang, Seung Gyo Jeong, Luca Buiarelli +24
Recently, rutile ruthenium dioxide (RuO) has attracted renewed interest due to expectations of prominent altermagnetic spin splitting. However, accumulating experimental eviden…
Magnetic field-induced momentum-dependent symmetry breaking in a kagome superconductor
Jianwei Huang, Zheng Ren, Hengxin Tan +17
When multiple degrees of freedom share similar energy scales in quantum materials, intertwined electronic orders, which exhibit broken symmetries, are often strongly coupled. Recen…
Atomically-sharp magnetic soliton in the square-net lattice EuRhAlSi
Kevin Allen, Juba Bouaziz, Yichen Zhang +17
Topological spin textures are hallmark manifestations of competing interactions in magnetic matter. Their effective description by nonlinear field theories reflects an energetic fr…
Quantum oscillations and anisotropic magnetoresistance in the quasi-two-dimensional Dirac nodal line superconductor
Yuxiang Gao, Kevin Allen, Rose Albu Mustaf +8
Recent interest in quantum materials has focused on systems exhibiting both superconductivity and non-trivial band topology as material candidates to realize topological or unconve…
Fermi surface and Berry phase analysis for Dirac nodal line semimetals: cautionary tale to SrGa and BaGa
Yuxiang Gao, Yichen Zhang, Shiming Lei +8
A Berry phase of odd multiples of inferred from quantum oscillations (QOs) has often been treated as evidence for nontrivial reciprocal space topology. However, disentangling…
Aspheric lens design proposal for near-perfect mode-matching of a broadband quantum dot micropillar to a single-mode fibre
Yichen Zhang, David Dlaka, James McDougall +5
Quantum dots in micropillars are one of the most promising options for a bright, deterministic single photon source. While highly efficient devices (>95%) have been designed, there…
