Field-Induced Magnon Decay, Magnon Shadows, and Roton-like Excitations in the Honeycomb Antiferromagnet YbBr
J. A. Hernández, A. A. Eberharter, M. Schuler +9
Although the search for quantum many-body phenomena in magnetic materials has a strong focus on highly frustrated systems, even unfrustrated quantum magnets show a multitude of unc…
Extracting the Speed of Light from Matrix Product States
Alexander A. Eberharter, Laurens Vanderstraeten, Frank Verstraete +1
We provide evidence that the spectrum of the local effective Hamiltonian and the transfer operator in infinite-system matrix product state simulations are identical up to a global…
Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe
Tao Xie, A. A. Eberharter, Jie Xing +14
Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly en…
Field-Induced Spin Excitations in the Spin-1/2 Triangular-Lattice Antiferromagnet CsYbSe
Tao Xie, Jie Xing, S. E. Nikitin +7
A layered triangular lattice with spin-1/2 ions is an ideal platform to explore highly entangled exotic states like quantum spin liquid (QSL). Here, we report a systematic in-field…
Diagnosing weakly first-order phase transitions by coupling to order parameters
Jonathan D'Emidio, Alexander A. Eberharter, Andreas M. Läuchli
The hunt for exotic quantum phase transitions described by emergent fractionalized degrees of freedom coupled to gauge fields requires a precise determination of the fixed point st…
