Symmetry-Breaking Supercollisions in Landau-Quantized Graphene [PDF]
Physical Review Letters, 2017 Recent pump-probe experiments performed on graphene in a perpendicular magnetic field have revealed carrier relaxation times ranging from picoseconds to nanoseconds depending on the quality of the sample. To explain this surprising behavior, we propose a novel symmetry-breaking defect-assisted relaxation channel.

Spacetime rotation-induced Landau quantization [PDF]
Physical Review D, 2012 We investigate non-inertial and gravitational effects on quantum states in electromagnetic fields and present the analytic solution for energy eigenstates for the Schr dinger equation including non-inertial, gravitational and electromagnetic effects.

Ultrafast carrier dynamics in Landau-quantized graphene
Nanophotonics, 2015 In an external magnetic field, the energy of massless charge carriers in graphene is quantized into non-equidistant degenerate Landau levels including a zero-energy level.

Controllable population dynamics in Landau-quantized graphene [PDF]
Scientific Reports, 2018 AbstractIn this paper, we carry out a theoretical investigation on the population dynamics of graphene system under continuous-wave (cw) laser and chirped pulse excitation. Results of our numerical simulations reveal that complete population transfer from an initially occupied ground state to the initially unoccupied excited states can be achieved by ...

Quantization and non-quantization of energy for higher-dimensional Ginzburg-Landau vortices [PDF]
, 2022 Given a family of critical points $u_ε:M^n\to\mathbb{C}$ for the complex Ginzburg--Landau energies \begin{align*} &E_ε(u)=\int_{M}\left(\frac{|du|^2}{2}+\frac{(1-|u|^2)^2}{4ε^2}\right), \end{align*} on a manifold $M$, with natural energy growth $E_ε(u_ε)=O(|\logε| )$, it is known that the vorticity sets $\{|u_ε|\leq \frac{1}{2}\}$ converge ...

Carrier multiplication in graphene under Landau quantization [PDF]
Nature Communications, 2014 Carrier multiplication is a many-particle process giving rise to the generation of multiple electron-hole pairs. This process holds the potential to increase the power conversion efficiency of photovoltaic devices. In graphene, carrier multiplication has been theoretically predicted and recently experimentally observed. However, due to the absence of a
