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…
Disorder-induced currents as signatures of chiral superconductivity
Madhuparna Karmakar, R. Ganesh
Chiral superconductors are expected to carry a spontaneous, chiral and perpetual current along the sample edge. However, despite the availability of several candidate materials, su…
Effect of In-Plane Shear Flow on the Magnetic Island Coalescence Instability
Jagannath Mahapatra, Arkaprava Bokshi, Rajaraman Ganesh +1
Using a 2D Viscoresistive Reduced MagnetoHydroDynamic (VR-RMHD) model, the magnetic island coalescence problem is studied in the presence of in-plane, parallel shear flows. Extendi…
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…
Collective excitations in vortices and vortex lattices
Bhargava B. A., R. Ganesh
Emergent lattices at mesoscopic length scales have evoked interest in several recent contexts, e.g., in crystalline arrangements of skyrmions. It is a challenging task to determine…
The attractive Hubbard model as an system of competing phases: supersolid order and its thermal melting
Madhuparna Karmakar, R. Ganesh
Competition between superconductivity and charge order is a recurring theme in contemporary condensed matter physics. This is quintessentially captured in the attractive Hubbard mo…
