Boson-Controlled Quantum Transport [PDF]
Physical Review Letters, 2007 We study the interplay of collective dynamics and damping in the presence of correlations and bosonic fluctuations within the framework of a newly proposed model, which captures the principal transport mechanisms that apply to a variety of physical systems. We establish close connections to the transport of lattice and spin polarons, or the dynamics of

Perfect absorption in complex scattering systems with or without hidden symmetries
Nature Communications, 2020 In the past, implementations of coherent perfect absorption relied on systems with symmetric conditions. Here, the authors demonstrate coherent perfect absorption in complex microwave scattering settings without requiring such symmetries.

Accessing the quantum world through electronic transport in carbon nanotubes [PDF]
, 2006 In this thesis we will focus on (a) superconducting electrodes attached to carbon nanotube quantum dots in order to study the effects of superconducting correlations on quantum systems and (b) local gate control of carbon nanotubes in order to define

Spin transport of excitons [PDF]
, 2009 We report on observation of the spin transport of spatially indirect excitons in GaAs/AlGaAs coupled quantum wells (CQW). Exciton spin transport over substantial distances, up to several micrometers in the present work, is achieved due to orders of ...

Phonon chirality tuned through interface transmission in a one-dimensional atomic junction model
New Journal of Physics, 2018 There has been growing interest in revealing exotic properties of chiral phonons since they were found in honeycomb AB lattice, and very recently they were experimentally verified in a tungsten diselenide monolayer (2018 Science 359 579).

Transport through Zero-Dimensional States in a Quantum Dot [PDF]
, 1990 We have studied the electron transport through zero-dimensional (0D) states. 0D states are formed when one-dimensional edge channels are confined in a quantum dot.

Quantum transport enhancement by time-reversal symmetry breaking [PDF]
, 2013 Quantum mechanics still provides new unexpected effects when considering the transport of energy and information. Models of continuous time quantum walks, which implicitly use time-reversal symmetric Hamiltonians, have been intensely used to investigate ...

Measurement-based quantum computing with a spin ensemble coupled to a stripline cavity [PDF]
, 2012 Recently, a new form of quantum memory was proposed. The storage medium is an ensemble of electron spins, coupled to a stripline cavity and an ancillary readout system.
