Optimal Path Planning with Localization constraints
Chinmay Mundane, Manav Mishra, PB Sujit
This paper studies UAV path planning in areas where GPS signals are not present. Because these drones can easily get lost when they don't have GPS, they must rely on dead reckoning…
Superconductivity from interband coupling to ferroelectric quantum critical fluctuations in two dimensions
Sudip Kumar Saha, Jonathan Ruhman, Avraham Klein
Soft critical fluctuations associated with ferroelectric quantum phase transitions are typically transverse owing to their polar nature. This implies that the conventional density-…
Interlayer Charge-Transfer Ferroelectric Fluctuations as a Pairing Mechanism in van der Waals Superconductors
Ankan Biswas, Jagannath Sutradhar, Sudip Kumar Saha +2
Signatures of unconventional superconductivity have been reported in a wide range of van der Waals (vdW) materials. However, their microscopic origin remains unclear due to competi…
Strong Coupling Theory of Superconductivity and Ferroelectric Quantum Criticality in metallic SrTiO
Sudip Kumar Saha, Maria N. Gastiasoro, Jonathan Ruhman +1
Superconductivity in doped SrTiO has remained an enduring mystery for over 50 years. The material's status as a ``quantum" ferroelectric metal, characterized by a soft polar mo…
