Exciton-polaron interactions in monolayer WS
Jack B. Muir, Jesper Levinsen, Stuart K. Earl +12
Interactions between quasiparticles are of fundamental importance and ultimately determine the macroscopic properties of quantum matter. A famous example is the phenomenon of super…
Multidimensional Analysis of Excitonic Spectra of Monolayers of Tungsten Disulphide: Towards Computer Aided Identification of Structural and Environmental Perturbations of 2D Materials
Pavel V. Kolesnichenko, Qianhui Zhang, Changxi Zheng +2
Despite 2D materials holding great promise for a broad range of applications, the proliferation of devices and their fulfillment of real-life demands are still far from being reali…
Super-transport of Excitons in Atomically Thin Organic Semiconductors at the 2D Quantum Limit
Ankur Sharma, Linglong Zhang, Jonathan O. Tollerud +13
Long-range and fast transport of coherent excitons is important for development of high-speed excitonic circuits and quantum computing applications. However, most of these coherent…
Disentangling the effects of doping, strain and defects in monolayer WS2 by optical spectroscopy
Pavel V. Kolesnichenko, Qianhui Zhang, Changxi Zheng +2
Monolayers of transition metal dichalcogenides (TMdC) are promising candidates for realization of a new generation of optoelectronic devices. The optical properties of these two-di…
Background-free time-resolved coherent Raman spectroscopy (CSRS and CARS): heterodyne detection of low-energy vibrations and recognition of excited-state contributions
Pavel Kolesnichenko, Jonathan O. Tollerud, Jeffrey A. Davis
Coherent Raman scattering (CRS) spectroscopy techniques have been widely developed and optimized for different applications in biomedicine and fundamental science. The most utilize…
Persistent coherence of quantum superpositions in an optimally doped cuprate revealed by 2D spectroscopy
Fabio Novelli, Jonathan O. Tollerud, Dharmalingam Prabhakaran +1
Understanding of the precise mechanisms of high-temperature superconductivity is elusive. In particular, in order to solve the puzzle of the pairing mechanism, it is important to u…
Transient THz conductivity of silicon with optical pumping above and below the second indirect transition
Fabio Novelli, Jeffrey A Davis
Here we perform a series of time-resolved experiments where a 100 fs pump pulse is tuned between 528 nm and 555 nm, across the second indirect gap of intrinsic silicon at ~540 nm w…
Revealing and Characterizing Dark Excitons Through Coherent Multidimensional Spectroscopy
Jonathan O. Tollerud, Steven T. Cundiff, Jeffrey A. Davis
Dark excitons are of fundamental importance in a broad range of contexts, but are difficult to study using conventional optical spectroscopy due to their weak interaction with ligh…
Two-dimensional double-quantum spectroscopy: peak shapes as a sensitive probe of carrier interactions in quantum wells
Jonathan O. Tollerud, Jeffrey A. Davis
We identify carrier scattering at densities below which it has previously been observed in semiconductor quantum wells. These effects are evident in the peakshapes of 2D double-qua…
Vibronic resonances facilitate excited state coherence in light harvesting proteins at room temperature
Fabio Novelli, Ahsan Nazir, Gethin H. Richards +4
Until recently it was believed that photosynthesis, a fundamental process for life on earth, could be fully understood with semi-classical models. However, puzzling quantum phenome…
Isolating quantum coherence with pathway-selective coherent multi-dimensional spectroscopy
Jonathan O Tollerud, Christopher R Hall, Jeffrey A Davis
Coherent coupling between spatially separated systems has long been explored as a necessary requirement for quantum information and cryptography. Recent discoveries suggest such ph…
