Symmetry-breaking-induced topology in FeSe
Mikel GarcÃa-DÃez, Jonas B. Profe, Augustin Davignon +3
FeSe has been one of the most intensively studied iron-based superconductors over the past two decades, exhibiting a wide range of phenomena such as unconventional superconductivit…

Symmetry-adapted sample-based quantum diagonalization: Application to lattice model
Kosuke Nogaki, Steffen Backes, Tomonori Shirakawa +2
We present a symmetry-adapted extension of sample-based quantum diagonalization (SQD) that rigorously embeds space-group symmetry into the many-body subspace sampled by quantum har…

Ab initio study on heavy-fermion behavior in LiVO: Role of Hund's coupling and stability
Steffen Backes, Yusuke Nomura, Ryotaro Arita +1
LiVO is a member of the so-called heavy fermion compounds, with effective electron mass exceeding 60 times the free electron mass, comparable to heavy fermion com…
