How alignment controls heat transport in polymer chains with kinks?
Igor V. Parshin, Igor V. Rubtsov, Alexander L. Burin
Thermal transport in polymer chains is commonly attributed to ballistic propagation of long-wavelength acoustic phonons, which act as Goldstone modes protected by translational sym…
Thermal conductivity of aligned polymers with kinks
Igor V. Parshin, Igor V. Rubtsov, Alexander L. Burin
Thermal conductivity of aligned polymer molecules can be exceptionally high along the alignment direction due to energy transport through strong covalent bonds. At the same time, i…
Super diffusive length dependent thermal conductivity in one-dimensional materials with structural defects: longitudinal to transverse phonon scattering leads to law
Alexander L. Burin
Structural defects in one-dimensional heat conductors couple longitudinal (stretching) and transverse (bending) vibrations. This coupling results in the scattering of longitudinal…
Two stage decoherence of optical phonons in long oligomers
Alexander L. Burin, Igor V. Rubtsov
Intramolecular energy transport is generally responsible for chemical energy balance in molecular systems. The transport is fast and efficient if energy is transferred by optical p…
Ballistic Energy Transport via Long Alkyl Chains: A New Initiation Mechanism
Sithara U. Nawagamuwage, Elliot S. Williams, Md Muhaiminul Islam +4
In an effort to increase the speed and efficiency of ballistic energy transport via oligomeric chains, we performed measurements of the transport in compounds featuring long alkyl…
Superdiffusion in random two dimensional system with time-reversal symmetry and long-range hopping
Xiaolong Deng, Ivan M. Khaymovich, Alexander L. Burin
Although it is recognized that Anderson localization takes place for all states at a dimension less or equal , while delocalization is expected for hopping decreasing…
Low temperature dipolar echo in amorphous dielectrics: Significance of relaxation and decoherence free two level systems
Alexander L. Burin, John M. Leveritt, Gudrun Fickenscher +6
The nature of dielectric echoes in amorphous solids at low temperatures is investigated. It is shown that at long delay times the echo amplitude is determined by a small subset of…
Squeezing Atomic Vibrations In An Optical Lattice. A New Mechanism Of Optical Cooling
A. L. Burin, J. L. Birman, A. Bulatov +1
We propose a new method to obtain a squeezed matter field of atomic vibrations by use of an optical lattice, and the laser pulse technique of Garrett et al used for acoustic phonon…
