Preparation and Decay of a Single Quantum of Vibration at Ambient Conditions

Christophe Marcel Georges Galland, Vivishek Sudhir, Mitchell David Anderson, Kilian Robert Seibold, Nils Kipfer

A single quantum of excitation of a mechanical oscillator is a textbook example of the principles of quantum physics. But mechanical oscillators, despite their pervasive presence in nature and modem technology, do not genetically exist in an excited Fock s ...

Polaritonic Cross Feshbach Resonance

Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Naotomo Takemura, Morteza Navadeh Toupchi

We demonstrate the existence of a cross Feshbach resonance by strongly driving a lower polariton mode and by monitoring in time the transmission of a short optical pulse at the energy of the upper polariton mode in a semiconductor microcavity. From the sig ...

Anderson localisation in steady states of microcavity polaritons

Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Fauzia Jabeen, Morteza Navadeh Toupchi, Albert Adiyatullin

We present an experimental signature of the Anderson localisation of microcavity polaritons, and provide a systematic study of the dependence on disorder strength. We reveal a controllable degree of localisation, as characterised by the inverse-participati ...

Two-Color Pump-Probe Measurement of Photonic Quantum Correlations Mediated by a Single Phonon

Vincenzo Savona, Christophe Marcel Georges Galland, Hugo Pierre Alexandre Flayac, Mitchell David Anderson, Kilian Robert Seibold, Santiago Tarrago Velez

We propose and demonstrate a versatile technique to measure the lifetime of the one-phonon Fock state using two-color pump-probe Raman scattering and spectrally resolved, time-correlated photon counting. Following pulsed laser excitation, the n = 1 phonon ...

Coherent and incoherent aspects of polariton dynamics in semiconductor microcavities

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Naotomo Takemura, Morteza Navadeh Toupchi, Souvik Biswas

The interaction between coherent polaritons and incoherent excitons plays an important role in polariton physics. Using resonant pump-probe spectroscopy with selective excitation of single polariton branches, we investigate the different dephasing mechanis ...

Independence of optical absorption on Auger ionization in single-walled carbon nanotubes revealed by ultrafast e-h photodoping

Mitchell David Anderson

Auger-ionized free-carriers in a one-dimensional semiconductor are predicted to result in a strong band-gap renormalization. Isolated single-walled carbon nanotubes (SWCNT) under high-intensity laser irradiation exhibit strong nonlinear photoluminescence ( ...

Temporally resolved second-order photon correlations of exciton-polariton Bose-Einstein condensate formation

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Mitchell David Anderson, Hadis Abbaspour, Albert Adiyatullin

Second-order time correlation measurements with a temporal resolution better than 3 ps were performed on a CdTe microcavity where spontaneous Bose-Einstein condensation is observed. After the laser pulse, the nonresonantly excited thermal polariton populat ...

Two-dimensional Fourier transform spectroscopy of exciton-polaritons and their interactions

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Stéphane Trebaol, Mitchell David Anderson, Naotomo Takemura, Verena Kohnle

We investigate polariton-polariton interactions in a semiconductor microcavity through two-dimensional Fourier transform (2DFT) spectroscopy. We observe, in addition to the lower-lower and the upper-upper polariton self-interactions, a lower-upper cross in ...

Dephasing effects on coherent exciton-polaritons and the breakdown of the strong coupling regime

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Stéphane Trebaol, Mitchell David Anderson, Naotomo Takemura, Souvik Biswas

Using femtosecond pump-probe spectroscopy, we identify excitation-induced dephasing as a major mechanism responsible for the breakdown of the strong coupling between excitons and photons in a semiconductor microcavity. The effects of dephasing are observed ...
