Magnetic-Field-Driven Dimensional Reduction in a Quantum Antiferromagnet
Subhankar Khatua, Marcin Raczkowski, Jeroen van den Brink +1
Low dimensionality enhances quantum fluctuations, triggering novel states of quantum matter to emerge. In real materials, low dimensionality usually arises from spatially strongly…
Observation of an emergent energy scale close to dimensional reduction in a quasi-two-dimensional quantum magnet
Anneke Reinold, Laur Peedu, Kirill Amelin +19
By appropriately perturbing a critical transverse-field Ising chain away from its critical point, the system can develop a finite correlation length with a characteristic purely ma…
Revealing altermagnetic Fermi surfaces with two Kondo impurities
Qiong Qin, Toshihiro Sato, Marcin Raczkowski +3
Motivated by recent advances in the study of altermagnetism, or unconventional magnetism, and in the realization and manipulation of two-impurity Kondo physics in real materials, w…
Dimensionality-Changing Transition from a Non-Fermi Liquid to a Spin-Solid in a Multichannel Kondo Lattice
Simon Martin, Marcin Raczkowski, Fakher F. Assaad +1
A multichannel Kondo system, where a single quantum spin couples to multiple channels of an electronic bath, provides one of the simplest examples of a zero-dimensional non-Fermi l…
Magnetization process of a quasi-two-dimensional quantum magnet: Two-step symmetry restoration and dimensional reduction
Anneke Reinold, Lucas Berger, Marcin Raczkowski +9
We report on a comprehensive thermodynamic study of a quasi-two-dimensional (quasi-2D) quantum magnet Cu(OH)Br which in the 2D layer can be viewed as strongly coupled alter…
Alteration of Topology in Quantum Phase Transitions via Symmetry Enrichment
Gabriel Rein, Marcin Raczkowski, Zhenjiu Wang +2
Topology plays a cardinal role in explaining phases and quantum phase transitions beyond the Landau-Ginzburg-Wilson paradigm. In this study, we formulate a set of models of Dirac f…
