Regularity of symbolic and ordinary powers of weighted oriented graphs and their upper bounds
Manohar Kumar, Ramakrishna Nanduri
In this paper, we compare the regularities of symbolic and ordinary powers of edge ideals of weighted oriented graphs. For any weighted oriented complete graph , we show that…
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…
Fractional statistics in anyon collisions
H. Bartolomei, M. Kumar, R. Bisognin +9
Two-dimensional systems can host exotic particles called anyons whose quantum statistics are neither bosonic nor fermionic. For example, the elementary excitations of the fractiona…
Microwave photons emitted by fractionally charged quasiparticles
R. Bisognin, H. Bartolomei, M. Kumar +8
Strongly correlated low-dimensional systems can host exotic elementary excitations carrying a fractional charge and potentially obeying anyonic statistics. In the fractional qu…
Extracting single electron wavefunctions from a quantum electrical current
A. Marguerite, B. Roussel, R. Bisognin +10
Quantum nanoelectronics has entered an era where quantum electrical currents are built from single to few on-demand elementary excitations. To date however, very limited tools have…
Gyrotropic Zener tunneling and nonlinear IV curves in the zero-energy Landau level of graphene in a strong magnetic field
Antti Laitinen, Manohar Kumar, Pertti Hakonen +1
We have investigated tunneling current through a suspended graphene Corbino disk in high magnetic fields at the Dirac point, i.e. at filling factor = 0. At the onset of the die…
