Emergent superconductivity upon disordering a topological insulator
Carlos Eduardo S. P. Corsino, Hermann Freire, Anurag Banerjee
We study the emergence of superconductivity in a quantum spin Hall insulator and identify a disorder-driven enhancement of pairing arising from quantum geometry. Using sign-problem…
Charge Modulation in the Vortex Halo of a Superconductor Enhances its Critical Magnetic Field
Anurag Banerjee, Catherine Pépin, Nandini Trivedi +1
When an orbital magnetic field suppresses superconductivity, forming periodic vortices in type-II superconductors, subdominant orders can emerge in the vortex cores. Rather than co…
Charge modulation in the background of depleted superconductivity inside vortices
Chiranjit Mahato, Anurag Banerjee, Catherine Pépin +1
We use the Bogoliubov-de Gennes (BDG) formalism to undertake a microscopic investigation of a vortex lattice in a strongly correlated, type-II, d-wave superconductor (SC) treating…
Chiral to Nematic Crossover in the Superconducting State of 4Hb-TaS
I. Silber, S. Mathimalar, I. Mangel +10
Most superconductors have an isotropic, single component order parameter, and are well described by the BCS theory for superconductivity. Unconventional, multiple components superc…
Charge density wave and superconductivity in 6R-TaS2
Sudip Pal, Prakash Bahera, S. R. Sahoo +6
The layered transition metal dichalcogenide compounds 1T-TaS2 and 4H-TaS2 are well known for their exotic properties, which include charge density wave, superconductivity, Mott tra…
Ferromagnetic exchange field stabilized antiferromagnetic ordering in a cuprate superconductor
Biswajit Dutta, A. Banerjee
We report experimental evidence of formation of antiferromagnetic clusters in composites made of a cuprate superconductor La1.85Sr0.15CuO4 (LCu) and a ferromagnet La0.6Sr0.4CoO3 (L…
Charge, bond, and pair density wave orders in a strongly correlated system
Anurag Banerjee, Catherine Pépin, Amit Ghosal
The coexistence of multiple quasi-degenerate orders is the hallmark of the strongly correlated materials. Experiments often reveal several spatially modulated orders in the underdo…
Pseudogap phase and fractionalization: Predictions for Josephson junction setup
Anurag Banerjee, Alvaro Ferraz, Catherine Pépin
The pseudogap regime of the underdoped cuprates arguably remains one of the most enigmatic phenomena of correlated quantum matter. Recent theoretical ideas suggest that a pair dens…
New paradigm for a disordered superconductor in a magnetic field
Anushree Datta, Anurag Banerjee, Nandini Trivedi +1
We show that while orbital magnetic field and disorder, acting individually weaken superconductivity, acting together they produce an intriguing evolution of a two-dimensional type…
Strange metal from incoherent bosons
Anurag Banerjee, Maxence Grandadam, Hermann Freire +1
The breakdown of the celebrated Fermi liquid theory in the strange metal phase is the central enigma of correlated quantum matter. Motivated by recent experiments reporting short-l…
Emergent superconductivity upon disordering a charge density wave ground state
Anurag Banerjee, Arti Garg, Amit Ghosal
We explore the interplay of a charge density wave (CDW) order and s-wave superconductivity (sSC) in a disordered system. Recent experiments on 1T-TiSe_2, where the pristine sample…
Magnetic field induced emergent inhomogeneity in a superconducting film with weak and homogeneous disorder
Rini Ganguly, Indranil Roy, Anurag Banerjee +3
When a magnetic field is applied, the mixed state of a conventional Type II superconductor gets destroyed at the upper critical field Hc2, where the normal vortex cores overlap wit…
