Kitaev Meets Affleck-Kennedy-Lieb-Tasaki: Competing Quantum Disorder in Spin-3/2 Honeycomb Systems
Sogen Ikegami, Kiyu Fukui, Rico Pohle +1
We investigate an S=3/2 quantum spin model on a two-dimensional honeycomb lattice that continuously interpolates between two paradigmatic quantum disordered states with distinct en…
Electron-phonon-coupled Langevin dynamics for strongly-correlated insulators
Rico Pohle, Yukitoshi Motome, Terumasa Tadano +1
The Landau-Lifshitz-Gilbert (LLG) equations are widely used to study spin dynamics in Mott insulators. However, because energy damping is typically introduced phenomenologically, t…
Nematic spin liquid in a spin-1 pyrochlore magnet and its realization in
Rico Pohle, Nic Shannon
The search for spin liquids, magnetic phases which lie outside the Landau paradigm, remains one of the central challenges for modern condensed matter physics. For a long time, the…
Classical spin liquid on the generalized four-color Kitaev model
Han Yan, Rico Pohle
While (1) spin liquids have been extensively studied in both quantum and classical regimes, exact classical spin liquids arising from models with nearest-neighbor…
Eight-color chiral spin liquid in the bilinear-biquadratic model with Kitaev interactions
Rico Pohle, Nic Shannon, Yukitoshi Motome
Multipolar spin systems provide a rich ground for the emergence of unexpected states of matter due to their enlarged spin degree of freedom. In this study, with a specific emphasis…
Ground state of the =1/2 pyrochlore Heisenberg antiferromagnet: A quantum spin liquid emergent from dimensional reduction
Rico Pohle, Youhei Yamaji, Masatoshi Imada
The quantum antiferromagnet on the pyrochlore lattice offers an archetypal frustrated system, which potentially realizes a quantum spin liquid characterized by the absence of stand…
Gravitational wave analogues in spin nematics and cold atoms
Leilee Chojnacki, Rico Pohle, Han Yan +2
Many large-scale phenomena in our Universe, such as gravitational waves, are challenging to reproduce in laboratory settings. However, parallels with condensed matter systems can p…
Curie-law crossover in spin liquids
Rico Pohle, Ludovic D. C. Jaubert
The Curie-Weiss law is widely used to estimate the strength of frustration in frustrated magnets. However, the Curie-Weiss law was originally derived as an estimate of magnetic cor…
Variational Benchmarks for Quantum Many-Body Problems
Dian Wu, Riccardo Rossi, Filippo Vicentini +30
The continued development of computational approaches to many-body ground-state problems in physics and chemistry calls for a consistent way to assess its overall progress. In this…
Spin Nematics Meet Spin Liquids: Exotic Quantum Phases in the Spin- Bilinear-Biquadratic Model with Kitaev Interactions
Rico Pohle, Nic Shannon, Yukitoshi Motome
Spin liquid crystals are magnetic analogs of liquid crystals, possessing properties of both liquids and solids, a typical example of which are spin nematics. Spin nematics share ma…
Semi-classical simulation of spin-1 magnets
Kimberly Remund, Rico Pohle, Yutaka Akagi +2
Theoretical studies of magnets have traditionally concentrated on either classical spins, or the extreme quantum limit of spin-1/2. However, magnets built of spin-1 moments are als…
Low-Energy Excitations of Skyrmion Crystals in a Centrosymmetric Kondo-Lattice Magnet: Decoupled Spin-Charge Excitations and Nonreciprocity
Rintaro Eto, Rico Pohle, Masahito Mochizuki
We theoretically study spin and charge excitations of skyrmion crystals stabilized by conduction-electron-mediated magnetic interactions via spin-charge coupling in a centrosymmetr…
Theory of CaCrO as a bilayer breathing-kagome magnet: Classical thermodynamics and semi-classical dynamics
Rico Pohle, Han Yan, Nic Shannon
CaCrO is a novel spin- magnet exhibiting spin liquid behaviour which sets it apart from any previously studied model or material. However, understanding Ca$_…
Half moons are pinch points with dispersion
Han Yan, Rico Pohle, Nic Shannon
"Pinch points," singular features observed in (quasi-)elastic neutron scattering, are a widely discussed hallmark of spin liquids with an emergent gauge symmetry. Much less attenti…
How many spin liquids are there in CaCrO?
Rico Pohle, Han Yan, Nic Shannon
The search for novel phases of matter is a central theme of modern physics, with some of the most intriguing examples provided by the spin liquids found in magnets with competing,…
Symmetry and optical selection rules in graphene quantum dots
Rico Pohle, Eleftheria G. Kavousanaki, Keshav M. Dani +1
Graphene quantum dots (GQD's) have optical properties which are very different from those of an extended graphene sheet. In this Article we explore how the size, shape and edge--st…
Reentrance of disorder in the anisotropic shuriken Ising model
Rico Pohle, Owen Benton, L. D. C. Jaubert
For a material to order upon cooling is common sense. What is more seldom is for disorder to reappear at lower temperature, which is known as reentrant behavior. Such resurgence of…
