Spin correlations, low-energy scales, and anisotropy scaling in kagome frustrated magnets
Phillip Popp, Stephan Rosenkranz, Arthur P. Ramirez +1
Neutron scattering is central to identifying quantum states of magnetic materials. In the search for quantum spin liquids, broad spectral features of inelastic spectra have been ci…
Short-range order and hidden energy scale in geometrically frustrated magnets
Arthur P. Ramirez, Sergey Syzranov
In geometrically frustrated (GF) magnets, conventional long-range order is suppressed due to the presence of primitive triangular structural units, and the nature of the ensuing gr…
Origin of the hidden energy scale and the -ratio in geometrically frustrated magnets
Phillip Popp, Arthur P. Ramirez, Sergey Syzranov
Sufficiently clean geometrically frustrated (GF) magnets are the largest class of candidate materials that may host quantum spin liquids (QSLs). Some of them have been shown to exh…
Quasispins of vacancy defects and their interactions in disordered antiferromagnets
Muhammad Sedik, Shijun Sun, Arthur P. Ramirez +1
Vacancy defects in disordered magnetic materials are known to act as effective spins, ``quasispins'', in response to an external magnetic field. In the dilute limit, the contributi…
Quasispins of vacancy defects in Ising chains with nearest- and next-to-nearest-neighbour interactions
Shijun Sun, Arthur P. Ramirez, Sergey Syzranov
Motivated by frustrated magnets and quasi-one-dimensional magnetic materials, we study the magnetic properties of 1D Ising chains with nearest-neighbour (NN) and weaker next-to-nea…
BCS-like disorder-driven instabilities and ultraviolet effects in nodal-line semimetals
Siyu Zhu, Sergey Syzranov
We study the effects of quenched disorder on electrons in a 3D nodal-line semimetal. Disorder leads to significant renormalisations of the quasiparticle properties due to ultraviol…
