J Chem Phys . 2025 Feb; 162(7). PMID: 39976207
In our previous work [Mondal et al., J. Chem. Phys. 162, 014114 (2025)], we developed several efficient computational approaches to simulate exciton-polariton dynamics described by the Holstein-Tavis-Cummings (HTC) Hamiltonian under...

J Chem Phys . 2025 Jan; 162(1. PMID: 39777510
We outline two general theoretical techniques to simulate polariton quantum dynamics and optical spectra under the collective coupling regimes described by a Holstein-Tavis-Cummings (HTC) model Hamiltonian. The first one takes...

Chng B, Ying W, Lai Y, Vamivakas A, Cundiff S, Krauss T, et al.
J Phys Chem Lett . 2024 Nov; 15(47):11773-11783. PMID: 39556114
Molecular polaritons, the hybridization of electronic states in molecules with photonic excitation inside a cavity, play an important role in fundamental quantum science and technology. Understanding the decoherence mechanism of...

Suzuki T, Singh R, Moody G, Assmann M, Bayer M, Ludwig A, et al.
Phys Rev B . 2024 Nov; 98(19). PMID: 39539757
The dephasing mechanisms of -shell and -shell excitons in an InAs self-assembled quantum dot ensemble are examined using two-dimensional coherent spectroscopy (2DCS). 2DCS provides a comprehensive picture of how the...

Mondal M, Koessler E, Provazza J, Vamivakas A, Cundiff S, Krauss T, et al.
J Chem Phys . 2023 Sep; 159(9). PMID: 37655761
We develop an accurate and numerically efficient non-adiabatic path-integral approach to simulate the non-linear spectroscopy of exciton-polariton systems. This approach is based on the partial linearized density matrix approach to...

Purz T, Hipsley B, Martin E, Ulbricht R, Cundiff S
Opt Express . 2022 Dec; 30(25):45008-45019. PMID: 36522912
We demonstrate rapid imaging based on four-wave mixing (FWM) by assessing the quality of advanced materials through measurement of their nonlinear response, exciton dephasing, and exciton lifetimes. We use a...

Purz T, Martin E, Holtzmann W, Rivera P, Alfrey A, Bates K, et al.
J Chem Phys . 2022 Jun; 156(21):214704. PMID: 35676152
Transition metal dichalcogenides (TMDs) are regarded as a possible material platform for quantum information science and related device applications. In TMD monolayers, the dephasing time and inhomogeneity are crucial parameters...

Day M, Bates K, Smallwood C, Owen R, Schroder T, Bielejec E, et al.
Phys Rev Lett . 2022 Jun; 128(20):203603. PMID: 35657853
We report tunable excitation-induced dipole-dipole interactions between silicon-vacancy color centers in diamond at cryogenic temperatures. These interactions couple centers into collective states, and excitation-induced shifts tag the excitation level of...

Purz T, Cundiff S, Martin E
Opt Lett . 2021 Oct; 46(19):4813-4816. PMID: 34598206
We show that accelerated nonlinear imaging, such as stimulated Raman scattering and pump-probe imaging, is enabled by an order of magnitude reduction of data acquisition time when replacing the exponentially-weighted-moving-average...

Opt Lett . 2021 Jul; 46(15):3556-3559. PMID: 34329223
A four-wave-mixing, frequency-comb-based, hyperspectral imaging technique that is spectrally precise and potentially rapid, and can in principle be applied to any material, is demonstrated in a near-diffraction-limited microscopy application.
