Topological pair density waves in kagome superconductors
Jia-Xin Yin, Xianxin Wu, Mark H. Fischer +3
The pair density wave (PDW) is an unconventional superconducting state exhibiting periodic pairing modulations due to pairing with finite momentum Q. In two dimensions, multiple Q…
Direct Observation of Channelised Supercurrents in a Kagome Superconductor
Matthijs Rog, Tycho J. Blom, Reinier Q. Regter +9
Superconductors are many-body quantum states in which current flows without dissipation. Theory predicts that supercurrents follow a relatively simple spatial pattern in both conve…
Computational access to lattice and long-wavelength physics in quantum mutual information
Patrick M. Lenggenhager, M. Michael Denner, Doruk Efe Gökmen +3
Quantum mutual information is an important tool for characterizing correlations in quantum many-body systems, but its numerical evaluation is often prohibitively expensive. While s…
Superconductivity in a Chern band: effect of time-reversal-symmetry breaking on superconductivity
Bernhard E. Lüscher, Mark H. Fischer
Time-reversal-symmetry breaking is generally understood to be detrimental for superconductivity. However, recent experiments found superconductivity emerging out of a normal state…
How quantum fluctuations freeze a classical liquid and then melt it into a topological one
Hao Chen, Dan Mao, Andrea Kouta Dagnino +5
Topologically ordered quantum liquids are highly sought-after quantum phases of matter, and recently, fractional Chern insulators (FCIs) joined the few experimental realizations of…
Long-range electron coherence in Kagome metals
Chunyu, Guo, Kaize Wang +17
The wave-like nature of electrons lies at the core of quantum mechanics, distinguishing them from classical particles. Landmark experiments have revealed phase coherence of mobile…
Tunable superconductivity coexisting with the anomalous Hall effect in 1T'-WS2
Md Shafayat Hossain, Qi Zhang, David Graf +25
Transition metal dichalcogenides are a family of quasi-two-dimensional materials that display a high technological potential due to their wide range of electronic ground states, e.…
Unconventional gapping behavior in a kagome superconductor
Md Shafayat Hossain, Qi Zhang, Eun Sang Choi +19
Determining the types of superconducting order in quantum materials is a challenge, especially when multiple degrees of freedom, such as bands or orbitals, contribute to the fermio…
Interplay of superconductivity and charge-density-wave order in kagome materials
Sofie Castro Holbæk, Mark H. Fischer
In the VSb ( K, Rb, Cs) kagome materials, superconductivity coexists with a charge density wave (CDW), constituting a new platform to study…
Chiral kagome superconductivity modulations with residual Fermi arcs in KV3Sb5 and CsV3Sb5
Hanbin Deng, Hailang Qin, Guowei Liu +26
Superconductivity involving finite momentum pairing can lead to spatial gap and pair density modulations, as well as Bogoliubov Fermi states within the superconducting gap. However…
Charge-4 Superconductivity in a Hubbard model
Martina O. Soldini, Mark H. Fischer, Titus Neupert
A phase of matter in which fermion quartets form a superconducting condensate, rather than the paradigmatic Cooper pairs, is a recurrent subject of experimental and theoretical stu…
Efficient Learning of a One-dimensional Density Functional Theory
M. Michael Denner, Mark H. Fischer, Titus Neupert
Density functional theory underlies the most successful and widely used numerical methods for electronic structure prediction of solids. However, it has the fundamental shortcoming…
