Coexistence of symmetry-protected topological order and Neel order in the spin-1/2 ladder antiferromagnet C9H18N2CuBr4
Tao Hong, Imam Makhfudz, Xianglin Ke +7
Topological phases of matter are beyond the paradigm of Landau's symmetry breaking and have challenged our understanding of condensed matter systems. Here we report a new type of s…
Field-tunable Berezinskii-Kosterlitz-Thouless correlations in a Heisenberg magnet
D. Opherden, M. S. J. Tepaske, F. Bärtl +10
We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk materia…
Evidence for pressure induced unconventional quantum criticality in the coupled spin ladder antiferromagnet CHNCuBr
Tao Hong, Tao Ying, Qing Huang +15
Quantum phase transitions in quantum matter occur at zero temperature between distinct ground states by tuning a nonthermal control parameter. Often, they can be accurately describ…
Magnetic order and disorder in a quasi-two-dimensional quantum Heisenberg antiferromagnet with randomized exchange
F. Xiao, W. J. A. Blackmore, B. M. Huddart +13
We present an investigation of the effect of randomizing exchange strengths in the square lattice quasi-two-dimensional quantum Heisenberg antiferromagnet (QuinH)Cu(Cl$…
Quantum criticality in the spin- Heisenberg chain system copper pyrazine dinitrate
Oliver Breunig, Markus Garst, Andreas Klümper +3
The magnetic insulator copper pyrazine dinitrate comprises antiferromagnetic spin-1/2 chains that are well described by the exactly solvable one-dimensional Heisenberg model, provi…
Direct observation of the Higgs amplitude mode in a two-dimensional quantum antiferromagnet near the quantum critical point
Tao Hong, Masashige Matsumoto, Yiming Qiu +12
Spontaneous symmetry-breaking quantum phase transitions play an essential role in condensed matter physics. The collective excitations in the broken-symmetry phase near the quantum…
