On the Role of Non-Diagonal System-Environment Interactions in Bridge-Mediated Electron Transfer
Nirmalendu Acharyya, Roman Ovcharenko, Benjamin P. Fingerhut
Bridge-mediated electron transfer (ET) between a donor and an acceptor is prototypical for the description of numerous most important ET scenarios. While multi-step ET and the inte…
Axial Anomaly in the Gauge Matrix Model
Nirmalendu Acharyya, Mahul Pandey, Sachindeo Vaidya
The Yang-Mills matrix model admits self-dual and anti-self-dual instantons. When coupled to flavors of massless quarks, the Euclidean Dirac equation in an instanton b…
Coherent Dynamics of the Off-Diagonal Spin-Boson Model in the Ultra-Strong Coupling Regime
Nirmalendu Acharyya, Martin Richter, Benjamin P. Fingerhut
Quantum mechanics describes the unitary time evolution of closed systems. In practice, every quantum system interacts with the environment leading to an irreversible loss of cohere…
Large Q factor with very small Whispering Gallery Modes resonators
Nirmalendu Acharyya, Gregory Kozyreff
Efficient micro-resonators simultaneously require a large quality factor and a small volume . However, the former is ultimately limited by bending losses, the unavoidable ra…
Multiple critical coupling and sensing in a microresonator-waveguide system
Nirmalendu Acharyya, Gregory Kozyreff
We study the optical transmission of a waveguide that is side-coupled to a high- circular microresonator. The coupling is critical if the intrinsic resonator losses equate the c…
