Pseudo-fermion functional renormalization group with magnetic fields
Vincent Noculak, Johannes Reuther
The pseudo-fermion functional renormalization group is generalized to treat spin Hamiltonians with finite magnetic fields, enabling its application to arbitrary spin lattice models…
Competing Gauge Fields and Entropically-Driven Spin Liquid to Spin Liquid Transition in non-Kramers Pyrochlores
Daniel Lozano-Gómez, Vincent Noculak, Jaan Oitmaa +4
Gauge theories are powerful tools in theoretical physics, allowing complex phenomena to be reduced to simple principles, and are used in both high-energy and condensed matter physi…
$\require{mhchem}$Quantum paramagnetism in the decorated square-kagome antiferromagnet $\ce{Na6Cu7BiO4(PO4)4Cl3}$
Nils Niggemann, Nikita Astrakhantsev, Arnaud Ralko +9
$\require{mhchem}$The square-kagome lattice Heisenberg antiferromagnet is a highly frustrated Hamiltonian whose material realizations have been scarce. We theoretically investigate…
Dynamics of KNi(SO) governed by proximity to a 3D spin liquid model
M. G. Gonzalez, V. Noculak, A. Sharma +9
Quantum spin liquids (QSLs) have become a key area of research in magnetism due to their remarkable properties, such as long-range entanglement, fractional excitations, pinch-point…
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…
Classical spin models of the windmill lattice and their relevance for PbCuTeO
Anna Fancelli, Johannes Reuther, Bella Lake
We investigate classical Heisenberg models on the distorted windmill lattice and discuss their applicability to the spin- spin liquid candidate PbCuTeO. We first consi…
Bilinear Majorana representations for spin operators with spin magnitudes
Yannik Schaden, Johannes Reuther
We present a classification of bilinear Majorana representations for spin- operators, based on the real irreducible matrix representations of SU(2). We identify two types of suc…
