Effective Floquet Hamiltonian in the low-frequency regime
Michael Vogl, Martin Rodriguez-Vega, Gregory A. Fiete
We develop a theory to derive effective Floquet Hamiltonians in the weak drive and low-frequency regime. We construct the theory in analogy with band theory for electrons in a spat…
Complex magnetic properties in the mixed 4f -5d double perovskite iridates Ln2ZnIrO6 (Ln = Nd, Sm, Eu & Gd)
M. Vogl, R. Morrow, A. A. Aczel +5
In this work, we report on the synthesis and magnetic properties of a series of double perovskites LnZnIrO with Ln = Nd, Sm, Eu & Gd. These compounds present new examples o…
Disordered magnetism in the double perovskite LaCaScIrO6 with a distorted fcc lattice of Ir4+
M. Vogl, G. Bastien, R. Sarkar +9
The synthesis and characterization of the previously unknown material LaCaScIrO is reported. LaCaScIrO presents a new example of the rare case of a double perovskite with t…
Kitaev Magnetism and Fractionalized Excitations in Double Perovskite Sm2ZnIrO6
Birender Singh, M. Vogl, S. Wurmehl +3
The quest for Kitaev spin liquids in particular three dimensional solids is long sought goal in condensed matter physics, as these states may give rise to exotic new types of quasi…
Analogue of Hamilton-Jacobi theory for the time-evolution operator
Michael Vogl, Pontus Laurell, Aaron D. Barr +1
In this paper we develop an analogue of Hamilton-Jacobi theory for the time-evolution operator of a quantum many-particle system. The theory offers a useful approach to develop app…
A non-perturbative theory of effective Hamiltonians: example of moiré materials
F. Rost, R. Gupta, M. Fleischmann +7
We demonstrate that there exists a continuum Hamiltonian that is formally the operator equivalent of the general tight-binding method, inheriting the associativi…
