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…
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…
Classical and quantum phases of the pyrochlore magnet with Heisenberg and Dzyaloshinskii-Moriya interactions
Vincent Noculak, Daniel Lozano-Gómez, Jaan Oitmaa +4
We investigate the ground state and critical temperature phase diagrams of the classical and quantum pyrochlore lattice with nearest-neighbor Heisenberg and Dzyaloshinskii-…
Enhanced symmetry-breaking tendencies in the pyrochlore antiferromagnet
Imre Hagymási, Vincent Noculak, Johannes Reuther
We investigate the ground-state properties of the nearest-neighbor pyrochlore Heisenberg antiferromagnet using two complementary numerical methods, density-matrix renormaliza…
Dimerization tendencies of the pyrochlore Heisenberg antiferromagnet: A functional renormalization group perspective
Max Hering, Vincent Noculak, Francesco Ferrari +2
We investigate the ground state properties of the spin- pyrochlore Heisenberg antiferromagnet using pseudofermion functional renormalization group techniques. The first part o…
Magnetic field induced quantum spin liquid in the two coupled trillium lattices of KNi(SO)
Ivica Zivkovic, Virgile Favre, Catalina Salazar Mejia +19
Quantum spin liquids are exotic states of matter which form when strongly frustrated magnetic interactions induce a highly entangled quantum paramagnet far below the energy scale o…
Functional renormalization group for frustrated magnets with nondiagonal spin interactions
Finn Lasse Buessen, Vincent Noculak, Simon Trebst +1
In the field of quantum magnetism, the advent of numerous spin-orbit assisted Mott insulating compounds, such as the family of Kitaev materials, has led to a growing interest in st…
