Unconventional orders in the maple-leaf ferro-antiferromagnetic Heisenberg model
Lasse Gresista, Dominik Kiese, Simon Trebst +1
Motivated by the search for unconventional orders in frustrated quantum magnets, we present a multi-method investigation into the nature of the quantum phase diagram of the spin-$1…
Intertwined Superconductivity and Magnetism from Repulsive Interactions in Kondo Bilayers
Clara S. Weber, Dominik Kiese, Dante M. Kennes +1
While superconductors are conventionally established by attractive interactions, higher-temperature mechanisms for emergent electronic pairing from strong repulsive electron-electr…
Pseudo-fermion functional renormalization group for spin models
Tobias Müller, Dominik Kiese, Nils Niggemann +5
For decades, frustrated quantum magnets have been a seed for scientific progress and innovation in condensed matter. As much as the numerical tools for low-dimensional quantum magn…
Spin-valley magnetism on the triangular moiré lattice with SU(4) breaking interactions
Lasse Gresista, Dominik Kiese, Simon Trebst +1
The discovery of correlated insulating states in moiré heterostructures has renewed the interest in strongly-coupled electron systems where spin and valley (or layer) degrees of fr…
Taming pseudo-fermion functional renormalization for quantum spins: Finite-temperatures and the Popov-Fedotov trick
Benedikt Schneider, Dominik Kiese, Björn Sbierski
The pseudo-fermion representation for quantum spins introduces unphysical states in the Hilbert space which can be projected out using the Popov-Fedotov trick. However, sta…
Pinch-points to half-moons and up in the stars: the kagome skymap
Dominik Kiese, Francesco Ferrari, Nikita Astrakhantsev +9
Pinch point singularities, associated with flat band magnetic excitations, are tell-tale signatures of Coulomb spin liquids. While their properties in the presence of quantum fluct…
Functional renormalization of spinless triangular-lattice fermions: -patch vs. truncated-unity scheme
Nico Gneist, Dominik Kiese, Ravn Henkel +3
We study competing orders of spinless fermions in the triangular-lattice Hubbard model with nearest-neighbor interaction. We calculate the effective, momentum-resolved two-particle…
Benchmark Calculations of Multiloop Pseudofermion fRG
Marc K. Ritter, Dominik Kiese, Tobias Müller +4
The pseudofermion functional renormalization group (pffRG) is a computational method for determining zero-temperature phase diagrams of frustrated quantum magnets. In a recent meth…
Moments and multiplets in moiré materials: A pseudo-fermion functional renormalization group for spin-valley models
Lasse Gresista, Dominik Kiese, Simon Trebst
The observation of strongly-correlated states in moiré systems has renewed the conceptual interest in magnetic systems with higher SU(4) spin symmetry, e.g. to describe Mott insula…
TMDs as a platform for spin liquid physics: A strong coupling study of twisted bilayer WSe
Dominik Kiese, Yuchi He, Ciarán Hickey +2
The advent of twisted moiré heterostructures as a playground for strongly correlated electron physics has led to a plethora of experimental and theoretical efforts seeking to unrav…
Multiloop functional renormalization group approach to quantum spin systems
Dominik Kiese, Tobias Mueller, Yasir Iqbal +2
Renormalization group methods are well-established tools for the (numerical) investigation of the low-energy properties of correlated quantum many-body systems, allowing to capture…
Cavity-induced quantum spin liquids
Alessio Chiocchetta, Dominik Kiese, Carl Philipp Zelle +2
Quantum spin liquids provide paradigmatic examples of highly entangled quantum states of matter. Frustration is the key mechanism to favor spin liquids over more conventional magne…
Realization of Nearly Dispersionless Bands with Strong Orbital Anisotropy from Destructive Interference in Twisted Bilayer MoS2
Lede Xian, Martin Claassen, Dominik Kiese +4
Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructur…
Emergence and stability of spin-valley entangled quantum liquids in moiré heterostructures
Dominik Kiese, Finn Lasse Buessen, Ciarán Hickey +2
Twisting moiré heterostructures to the flatband regime allows for the formation of strongly correlated quantum states, since the dramatic reduction of the bandwidth can cause the r…
Spin-orbit entangled j=1/2 moments in BaCeIrO -- a frustrated fcc quantum magnet
A. Revelli, C. C. Loo, D. Kiese +16
We establish the double perovskite BaCeIrO as a nearly ideal model system for j=1/2 moments, with resonant inelastic x-ray scattering indicating a deviation of less than 1%…
