Quantum phase transition at non-zero doping in a random - model
Leyna Shackleton, Alexander Wietek, Antoine Georges +1
We present exact diagonalization results on finite clusters of a - model of spin-1/2 electrons with random all-to-all hopping and exchange interactions. We argue that such ra…
Stripes, Antiferromagnetism, and the Pseudogap in the Doped Hubbard Model at Finite Temperature
Alexander Wietek, Yuan-Yao He, Steven R. White +2
The interplay between thermal and quantum fluctuations controls the competition between phases of matter in strongly correlated electron systems. We study finite-temperature proper…
Loop-gas description of the localized-magnon states on the kagome lattice with open boundary conditions
Andreas Honecker, Johannes Richter, Jürgen Schnack +1
The high-field regime of the spin-s XXZ antiferromagnet on the kagome lattice gives rise to macroscopically degenerate ground states thanks to a completely flat lowest single-magno…
SU Chiral Spin Liquid on the Square Lattice: a View from Symmetric PEPS
Ji-Yao Chen, Sylvain Capponi, Alexander Wietek +3
Quantum spin liquids can be faithfully represented and efficiently characterized within the framework of Projected Entangled Pair States (PEPS). Guided by extensive exact diagonali…
