Near-field relaxation of a quantum emitter to 2D semiconductors: surface dissipation and exciton polaritons
(2016)The total spontaneous emission rate of a quantum emitter in the presence of an infinite MoS2 monolayer is enhanced by several orders of magnitude, compared to its free-space value, due to the excitation of surface exciton ... -
Quantum control of excitons for reversible heat transfer
(2019)Lasers, photovoltaics, and thermoelectrically-pumped light emitting diodes are thermodynamic machines which use excitons (electron-hole pairs) as the working medium. The heat transfers in such devices are highly irreversible, ... -
Quantum heat statistics with time-evolving matrix product operators
(2021)We present a numerically exact method to compute the full counting statistics of heat transfer in non-Markovian open quantum systems, which is based on the time-evolving matrix product operator algorithm. This approach is ... -
Synchronization in disordered oscillator lattices: Nonequilibrium phase transition for driven-dissipative bosons
(2021)We show that lattices of phase oscillators with random natural frequencies undergo a transition from a desynchronized to a synchronized state for dimensions d<4. The oscillators are described by a generalization of the ... -
Weyl points and exceptional rings with polaritons in bulk semiconductors
(2020)Weyl points are the simplest topologically protected degeneracy in a three-dimensional dispersion relation. The realization of Weyl semimetals in photonic crystals has allowed these singularities and their consequences to ...
