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…
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…
Skyrmion-like textures in superconductors with competing order
V. Saran, Madhuparna Karmakar, R. Ganesh
Vortex cores in a superconductor can develop structure and manifest competing orders. In strong magnetic fields, the inter-vortex distance can become short enough for vortex cores…
Vortex core ordering in Abrikosov lattices
Madhuparna Karmakar, R. Ganesh
Vortex lattices, arising from repulsive inter-vortex interactions, are a canonical example of emergent phenomena. Recent studies on the cuprates have drawn attention to the appeara…
Electronic correlations stabilizing time-reversal broken chiral superconductivity in single-trilayer TiSe
R. Ganesh, G. Baskaran, Jeroen van den Brink +1
Bulk TiSe is an intrinsically layered transition metal dichalcogenide (TMD) hosting both superconducting and charge density wave (CDW) ordering. Motivated by the recent progres…
Collective modes and superflow instabilities of strongly correlated Fermi superfluids
R. Ganesh, A. Paramekanti, A. A. Burkov
We study the superfluid phase of the one-band attractive Hubbard model of fermions as a prototype of a strongly correlated s-wave fermion superfluid on a lattice. We show that the…
