Quantum Coulomb Liquids of Different Rank in the Breathing Pyrochlore Antiferromagnet
Lasse Gresista, Daniel Lozano-Gómez, Matthias Vojta +2
Emergent gauge fields and Coulomb liquids have long been central to the physics of frustrated pyrochlore magnets, yet their realization beyond conventional, i.e. rank-1 , spi…
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…
Quantum effects on pyrochlore higher-rank U(1) spin liquids: Pinch-line singularities, spin nematics, and connections to oxide materials
Lasse Gresista, Daniel Lozano-Gómez, Matthias Vojta +2
Motivated by the magnetism of pyrochlore oxides, we consider the effect of quantum fluctuations in the most general symmetry-allowed nearest-neighbor Kramers exchange Hamiltonian o…
Noncoplanar orders and quantum disordered states in maple-leaf (anti)ferromagnets
Martin Gembé, Lasse Gresista, Heinz-Jürgen Schmidt +3
A promising route towards the realization of chiral spin liquids is the quantum melting of classically noncoplanar spin states via quantum fluctuations. In the classical realm, suc…
Candidate quantum disordered intermediate phase in the Heisenberg antiferromagnet on the maple-leaf lattice
Lasse Gresista, Ciarán Hickey, Simon Trebst +1
Quantum antiferromagnets on geometrically frustrated lattices have long attracted interest for the formation of quantum disordered states and the possible emergence of quantum spin…
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…
Network of chiral one-dimensional channels and localized states emerging in a moiré system
Jeyong Park, Lasse Gresista, Simon Trebst +2
Moiré systems provide a highly tunable platform for engineering band structures and exotic correlated phases. Here, we theoretically study a model for a single layer of graphene su…
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…
Dimensional crossover for universal scaling far from equilibrium
Lasse Gresista, Torsten V. Zache, Jürgen Berges
We perform a dynamical finite-size scaling analysis of a nonequilibrium Bose gas which is confined in the transverse plane. Varying the transverse size, we establish a dimensional…
