Two-temperature scales in the triangular-lattice Heisenberg antiferromagnet
Lei Chen, Dai-Wei Qu, Han Li +5
The anomalous thermodynamic properties of the paradigmatic frustrated spin-1/2 triangular lattice Heisenberg antiferromagnet (TLH) has remained an open topic of research over decad…
Hundness versus Mottness in a three-band Hubbard-Hund model: On the origin of strong correlations in Hund metals
Katharina M. Stadler, Gabriel Kotliar, Andreas Weichselbaum +1
Hund metals are multi-orbital systems with moderate Coulomb interaction, , and sizeable Hund's rule coupling, , that aligns the spins in different orbitals. They show stron…
Non-Topological Majorana Zero Modes in Inhomogeneous Spin Ladders
Neil J. Robinson, Alexander Altland, Reinhold Egger +6
We show that the coupling of homogeneous Heisenberg spin-1/2 ladders in different phases leads to the formation of interfacial zero energy Majorana bound states. Unlike Majorana bo…
Unified Phase Diagram of Antiferromagnetic SU(N) Spin Ladders
Andreas Weichselbaum, Sylvain Capponi, Philippe Lecheminant +2
Motivated by near-term experiments with ultracold alkaline-earth atoms confined to optical lattices, we establish numerically and analytically the phase diagram of two-leg SU()…
Exponential Thermal Tensor Network Approach for Quantum Lattice Models
Bin-Bin Chen, Lei Chen, Ziyu Chen +2
We speed up thermal simulations of quantum many-body systems in both one- (1D) and two-dimensional (2D) models in an exponential way by iteratively projecting the thermal density m…
