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…
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…
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…
