Magnetic and phononic dynamics in the two-ladder quantum magnet (C5H9NH3)2CuBr4
J. Philippe, F. Elson, T. Arh +20
In quantum magnetic materials it is common to observe both static and dynamic lattice effects on the magnetic excitation spectrum. Less common is to find that the magnetic correlat…
Randomness and Frustration in a S = 1/2 Square-Lattice Heisenberg Antiferromagnet
Ellen Fogh, Otto Mustonen, Peter Babkevich +7
We explore the interplay between randomness and magnetic frustration in the series of Heisenberg square-lattice compounds SrCuTeWO. Substituting W for…
Finite-Temperature Charge Dynamics and the Melting of the Mott Insulator
Xing-Jie Han, Chuang Chen, Jing Chen +6
The Mott insulator is the quintessential strongly correlated electronic state. We obtain complete insight into the physics of the two-dimensional Mott insulator by extending the sl…
Thermodynamic properties of highly frustrated quantum spin ladders: influence of many-particle bound states
A. Honecker, S. Wessel, R. Kerkdyk +3
Quantum antiferromagnets have proven to be some of the cleanest realizations available for theoretical, numerical, and experimental studies of quantum fluctuation effects. At finit…
Quantum and classical criticality in a dimerized quantum antiferromagnet
P. Merchant, B. Normand, K. W. Krämer +3
A quantum critical point (QCP) is a singularity in the phase diagram arising due to quantum mechanical fluctuations. The exotic properties of some of the most enigmatic physical sy…
Hubbard Model on the Pyrochlore Lattice: a 3D Quantum Spin Liquid
B. Normand, Z. Nussinov
We demonstrate that the insulating one-band Hubbard model on the pyrochlore lattice contains, for realistic parameters, an extended quantum spin-liquid phase. This is a three-dimen…
