Light-matter interaction inside an optical cavity: A perspective

Anneswa Paul, Upendra Harbola

Light-matter interaction inside an optical cavity and formation of polaritonic states have gained interest in the past decades as it has direct applications in many research fields…

Pump-intensity-scaling of Two-Photon-Absorption and Photon Statistics of Entangled-Photon Fields

Deependra Jadoun, Upendra Harbola, Vladimir Y. Chernyak +1

We use a non-perturbative theoretical approach to the parametric down-conversion (PDC) process, which generates entangled-photon field for an arbitrarily strong pump-pulse. This ap…

Tagged particle dynamics in supercooled quantum liquid

Ankita Das, Gopika Krishnan, Eran Rabani +1

We analyze dynamics of quantum supercooled liquids in terms of tagged particle dynamics. Unlike the classical case, uncertainty in the position of a particle in quantum liquid lead…

Frequency-dependent specific heat in quantum supercooled liquids: A mode-coupling study

Ankita Das, Eran Rabani, Kunimasa Miyazaki +1

Frequency-dependence of specific heat in supercooled hard sphere liquid is computed using quantum mode-coupling theory (QMCT). Mode-coupling equations are solved using recently pro…

Two-dimensional spectroscopy of open quantum systems

Haoran Sun, Upendra Harbola, Shaul Mukamel +1

Two-dimensional spectroscopy is discussed for open quantum systems with multiple simultaneously measurable fluxes. In particular, we discuss a junction where optical measurements o…

Nonlinear optical spectroscopy of open quantum systems

Haoran Sun, Upendra Harbola, Shaul Mukamel +1

Development of experimental techniques at nanoscale resulted in ability to perform spectroscopic measurements on single-molecule current carrying junctions. These experiments are n…
