Gaplessness from disorder and quantum geometry in gapped superconductors
Omri Lesser, Sagnik Banerjee, Xuepeng Wang +3
It is well known that disorder can induce low-energy Andreev bound states in a sign-changing, but fully gapped, superconductor at junctions. Generically, these excitations are…
Superconductivity in epitaxial PtSb(0001) thin films
C. Müller, S. P. Bommanaboyena, A. Badura +12
We report superconductivity in epitaxial PtSb(0001) thin films grown on SrF2(111). Electrical transport measurements reveal a superconducting transition at K.…
Emergent Synaptic Plasticity from Tunable Dynamics of Probabilistic Bits
Sagnik Banerjee, Shiva T. Konakanchi, Supriyo Datta +1
Probabilistic (p-) computing, which leverages the stochasticity of its building blocks (p-bits) to solve a variety of computationally hard problems, has recently emerged as a promi…
Electrically Tunable Picosecond-scale Octupole Fluctuations in Chiral Antiferromagnets
Shiva T. Konakanchi, Sagnik Banerjee, Mohammad M. Rahman +4
We present a theory for the relaxation time of the octupole order parameter in nanoscale chiral antiferromagnets (AFMs) coupled to thermal baths and spin injection sources. Using s…
