Unique Continuation Inequalities for the Schrödinger equations associated with the Special Hermite operators
Jayanta Sarkar
We investigate unique continuation inequalities for solutions of the Schrödinger equations associated with special Hermite operators. Our main result establishes that if the soluti…
Weighted estimates for Hardy-Littlewood maximal functions on Harmonic groups
Pritam Ganguly, Tapendu Rana, Jayanta Sarkar
Our aim in this article is to study the weighted boundedness of the centered Hardy-Littlewood maximal operator in Harmonic groups. Following Ombrosi et al. \cite{ORR}, we defi…
An analogue of Ingham's theorem on the Heisenberg group
Sayan Bagchi, Pritam Ganguly, Jayanta Sarkar +1
We prove an exact analogue of Ingham's uncertainty principle for the group Fourier transform on the Heisenberg group. This is accomplished by explicitly constructing compactly supp…
Suppression of noise in graphene due to non-scalar mobility fluctuations induced by impurity motion
Masahiro Kamada, Weijun Zeng, Antti Laitinen +5
Low frequency resistance variations due to mobility fluctuations is one of the key factors of noise in metallic conductors. According to theory, such noise in a two-dimension…
Electrical low-frequency noise due to surface diffusion of scatterers on an ultra low noise graphene platform
Masahiro Kamada, Antti Laitinen, Weijun Zeng +5
Low-frequency noise is ubiquitous, even in high-end electronic devices. For qubits such noise results in decrease of their coherence times. Recently, it was found that adso…
Strong magnetoresistance in a graphene Corbino disk at low magnetic fields
Masahiro Kamada, Vanessa Gall, Jayanta Sarkar +4
We have measured magnetoresistance of suspended graphene in the Corbino geometry at magnetic fields up to T, i.e., in a regime uninfluenced by Shubnikov-de Haas oscillati…
