Linear-time generalized Hartree-Fock algorithm for quasi-one-dimensional systems
Alex Meiburg, Bela Bauer
In many approximate approaches to fermionic quantum many-body systems, such as Hartree-Fock and density functional theory, solving a system of non-interacting fermions coupled to s…
Quantum impurity models using superpositions of fermionic Gaussian states: Practical methods and applications
Samuel Boutin, Bela Bauer
The coherent superposition of non-orthogonal fermionic Gaussian states has been shown to be an efficient approximation to the ground states of quantum impurity problems [Bravyi and…
Efficient matrix-product-state preparation of highly entangled trial states: Weak Mott insulators on the triangular lattice revisited
Amir M Aghaei, Bela Bauer, Kirill Shtengel +1
Using tensor network states to unravel the physics of quantum spin liquids in minimal, yet generic microscopic spin or electronic models remains notoriously challenging. A prominen…
Emergent Fermi surface in a triangular-lattice SU(4) quantum antiferromagnet
Anna Keselman, Bela Bauer, Cenke Xu +1
Motivated by multiple possible physical realizations, we study the SU(4) quantum antiferromagnet with a fundamental representation on each site of the triangular lattice. We provid…
Matrix product state algorithms for Gaussian fermionic states
Norbert Schuch, Bela Bauer
While general quantum many-body systems require exponential resources to be simulated on a classical computer, systems of non-interacting fermions can be simulated exactly using po…
Symmetry-protected non-Fermi liquids, Kagome spin liquids, and the chiral Kondo lattice model
Bela Bauer, Brendan P. Keller, Simon Trebst +1
The theoretical description of non-Fermi liquids is among the most challenging questions in strongly correlated quantum matter. While there are many experimental candidates for suc…
