Unconventional Superconductivity in the Chiral Topological Semimetal Ag2Pd3S
Roshan Kumar Kushwaha, Dibyendu Samanta, Sudarshan Sharma +15
Chiral crystals provide a unique setting where broken inversion symmetry, strong spin-orbit coupling, and electronic topology intertwine, yet superconductivity in intrinsically chi…
Nonunitary triplet superconductivity in the Z2 topological metal SrPd2As2
Aarti, Dibyendu Samanta, Kartik Panda +9
In Z2 topological metals, nontrivial band topology and strong spin-orbit coupling (SOC) impose symmetry constraints that can stabilize unconventional superconducting states, even w…
Giant Spin Magnetization from Quantum Geometry in Altermagnets
Neelanjan Chakraborti, Sudeep Kumar Ghosh, Snehasish Nandy
Altermagnets host spin-split band structures while exhibiting vanishing equilibrium spin magnetization, making field-induced responses a direct probe of their quantum geometry. A c…
Josephson diode effect in multichannel Rashba nanowires: Role of inter-subband coupling
Ardamon Sten, Sudeep Kumar Ghosh
The Josephson diode effect (JDE) has attracted significant attention for enabling directional, dissipationless supercurrents, positioning Josephson junctions as promising building…
Probing persistent spin textures through nonlinear magnetotransport
Neelanjan Chakraborti, Akash Dey, Snehasish Nandy +2
Persistent spin textures (PST) are special spin configurations in spin-orbit-coupled systems in which the spin polarization acquires a symmetry-enforced momentum-independent orient…
Superconducting diode effect in multichannel Majorana wires
Sagar Santra, Dibyendu Samanta, Sudeep Kumar Ghosh
The superconducting diode effect (SDE) enables nonreciprocal dissipationless transport when inversion and time-reversal symmetries are simultaneously broken. Rashba nanowires proxi…
Hourglass Dirac chains enable intrinsic topological superconductivity in nonsymmorphic silicides
Shashank Srivastava, Dibyendu Samanta, Pavan Kumar Meena +8
Nonsymmorphic crystalline symmetries provide a robust route to symmetry-protected electronic topology, yet their role in stabilizing intrinsic topological superconductivity remains…
Intrinsic Nonlinear Gyrotropic Magnetic Effect Governed by Spin-Rotation Quantum Geometry
Neelanjan Chakraborti, Snehasish Nandy, Sudeep Kumar Ghosh
Nonlinear magnetic response driven by time-periodic magnetic fields offers a distinct route to probe spin-resolved quantum geometry beyond conventional electric-field-driven nonlin…
Observation of Time-Reversal Symmetry Breaking in the Type-I Superconductor YbSb
Anshu Kataria, Shashank Srivastava, Dibyendu Samanta +9
The spontaneous breaking of time-reversal symmetry is a hallmark of unconventional superconductivity, typically observed in type-II superconductors. Here, we report evidence of tim…
