Berry phase in the rigid rotor: the emergent physics of odd antiferromagnets
Subhankar Khatua, R. Ganesh
The rigid rotor is a classic problem in quantum mechanics, describing the dynamics of a rigid body with its centre of mass held fixed. The configuration space of this problem is $S…
State selection in frustrated magnets
Subhankar Khatua, Sarvesh Srinivasan, R. Ganesh
Magnets with frustration often show accidental degeneracies, characterized by a large classical ground-state space (CGSS). Quantum fluctuations may `select' one of these ground sta…
Order by singularity in Kitaev clusters
Sarvesh Srinivasan, Subhankar Khatua, G. Baskaran +1
The Kitaev model is a beautiful example of frustrated interactions giving rise to deep and unexpected phenomena. In particular, its classical version has remarkable properties stem…
Effective theories for quantum spin clusters: Geometric phases and state selection by singularity
Subhankar Khatua, Diptiman Sen, R. Ganesh
Magnetic systems with frustration often have large classical degeneracy. We show that their low-energy physics can be understood as dynamics within the space of classical ground st…
