Chiral Y junction of quantum spin chains
F. Buccheri, R. Egger, R. G. Pereira +1
We study a Y junction of spin-1/2 Heisenberg chains with an interaction that breaks both time-reversal and chain exchange symmetries, but not their product nor SU(2) symmetry. The…

Quantum spin circulator in Y junctions of Heisenberg chains
F. Buccheri, R. Egger, R. G. Pereira +1
We show that a quantum spin circulator, a nonreciprocal device that routes spin currents without any charge transport, can be achieved in Y junctions of identical spin- Heisen…
