Topologically Protected Surface Altermagnetism on Antiferromagnets
Valentin Leeb, Peru d'Ornellas, Fernando de Juan +1
Altermagnetism (AM) and its associated spin-transport phenomena are typically linked to spin-split electronic band structures in bulk materials. However, the crystal surface has a…
A graphical diagnostic of topological order using ZX calculus
Sergi Mas-Mendoza, Richard D. P. East, Michele Filippone +1
Establishing a universal diagnostic of topological order remains an open theoretical challenge. In particular, diagnosing long-range entanglement through the entropic area law suff…
Fractonic Fractional Quantum Hall Effect
Justin Schirmann, Peru d'Ornellas, Charles Stahl +1
In non-interacting systems, disorder can drive a trivial phase into a topological one. However little is known how to construct a fractional quantum Hall ground-state, a paradigmat…
Altermagnetism Without Crystal Symmetry
Peru d'Ornellas, Valentin Leeb, Adolfo G. Grushin +1
Altermagnetism is a collinear magnetic order in which opposite spin species are exchanged under a real-space rotation. Hence, the search for physical realizations has focussed on c…
Giant quantum oscillations in thermal transport in low-density metals via electron absorption of phonons
B. Bermond, R. Wawrzynczak, S. Zherlitsyn +14
Oscillations of conductance observed in strong magnetic fields are a striking manifestation of the quantum dynamics of charge carriers in solids. The large charge carrier density i…
Doping-induced nematic and stripe orders within the charge density wave state of TiSe
Daniel Muñoz-Segovia, Jörn W. F. Venderbos, Adolfo G. Grushin +1
In this work, we present a theory to address conflicting experimental claims regarding the charge density wave (CDW) state in TiSe, including whether there is a single or multi…
