The Widom line in the Ising model on a decorated bilayer lattice
Joseph Chapman, Justas Gidziunas, Bruno Tomasello +1
There has been much recent interest devoted to a class of frustrated one-dimensional statistical mechanics lattice models which exhibit sharp thermodynamics. In this work, we study…
Theory of the spin Seebeck effect influenced by crystal-field excitations in TbFeO
Michiyasu Mori, Bruno Tomasello, Timothy Ziman
The spin Seebeck effect (SSE) is a phenomenon of thermoelectric generation that occurs within a device consisting of a bilayer of a metal and a ferromagnet. When TbFeO$_{12…
Bifurcation in correlation length of the Ising model on a "Toblerone" lattice
Joseph Chapman, Bruno Tomasello, Sam T. Carr
The classical Ising chain is the paradigm for the non-existence of phase transitions in 1D systems and was solved by Ernst Ising one hundred years ago. More recently, a decorated t…
Origin and dynamics of umbrella states in rare-earth iron garnets
Bruno Tomasello, Dan Mannix, Stephan Geprägs +1
Rare-earth iron garnets FeO are fascinating insulators with very diverse magnetic phases. Their strong potential in spintronic devices has encouraged a renewal…
Magnetic order and single-ion anisotropy in TbGaO
R. Wawrzyńczak, B. Tomasello, P. Manuel +8
Terbium gallium garnet (TGG), TbGaO, is well known for its applications in laser optics, but also exhibits complex low-temperature magnetism that is not yet fully un…
Correlated Quantum Tunnelling of Monopoles in Spin Ice
Bruno Tomasello, Claudio Castelnovo, Roderich Moessner +1
The spin ice materials HoTiO and DyTiO are by now perhaps the best-studied classical frustrated magnets. A crucial step towards the understandin…
Single-ion anisotropy and magnetic field response in spin ice materials HoTiO and DyTiO
Bruno Tomasello, Claudio Castelnovo, Roderich Moessner +1
Motivated by its role as a central pillar of current theories of dynamics of spin ice in and out of equilibrium, we study the single-ion dynamics of the magnetic rare earth ions in…
Quantum discord in a spin system with symmetry breaking
Bruno Tomasello, Davide Rossini, Alioscia Hamma +1
We analyze the quantum discord Q throughout the low-temperature phase diagram of the quantum XY model in transverse field. We first focus on the T=0 order-disorder quantum phase tr…
Ground state factorization and correlations with broken symmetry
Bruno Tomasello, Davide Rossini, Alioscia Hamma +1
We show how the phenomenon of factorization in a quantum many body system is of collective nature. To this aim we study the quantum discord in the one dimensional XY model in a…
