Field-induced phases in generalized Kitaev models and materials

ORAL

Abstract

By using a combination of exact diagonalization and semi-classical calculations we present a detailed analysis of possible field-induced phases obtained by adding to the Kitaev model further interaction terms. In particular we discuss the possibility of the appearance of topologically non-trivial field-induced spin liquid phases and the implications of these results in relation to the most studied α-RuCl3 [1,2].
