Thermodynamic perspective on quantum fluctuations
Akira Sone, Kanu Sinha, Sebastian Deffner
What is the major difference between large and small systems? At small length-scales the dynamics is dominated by fluctuations, whereas at large scales fluctuations are irrelevant.…
Radiative Properties of an Artificial Atom coupled to a Josephson Junction Array
Kanu Sinha, Saeed A. Khan, Elif Cüce +1
We study the radiative properties -- the Lamb shift, Purcell decay rate and the spontaneous emission dynamics -- of an artificial atom coupled to a long, multimode cavity formed by…
Dipoles in blackbody radiation: Momentum fluctuations, decoherence, and drag force
Kanu Sinha, Peter W. Milonni
A general expression is derived for the momentum diffusion constant of a small polarizable particle in blackbody radiation, and is shown to be closely related to the long-wavelengt…
Observation of vacuum-induced collective quantum beats
Hyok Sang Han, Ahreum Lee, Kanupriya Sinha +2
We demonstrate collectively enhanced vacuum-induced quantum beat dynamics from a three-level V-type atomic system. Exciting a dilute atomic gas of magneto-optically trapped …
Dissipative dynamics of a particle coupled to field via internal degrees of freedom
Kanupriya Sinha, Adrián Ezequiel Rubio López, Yiğit Subaşı
We study the non-equilibrium dissipative dynamics of the center of mass of a particle coupled to a field via its internal degrees of freedom. We model the internal and external deg…
Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
Collective radiation from distant emitters
Kanu Sinha, Alejandro González-Tudela, Yong Lu +1
Waveguides allow for direct coupling of emitters separated by large distances, offering a path to connect remote quantum systems. However, when facing the distances needed for prac…
Quantum Brownian Motion of a particle from Casimir-Polder Interactions
Kanupriya Sinha, Yigit Subasi
We study the fluctuation-induced dissipative dynamics of the quantized center of mass motion of a polarizable dielectric particle trapped near a surface. The particle's center of m…
Non-Markovian collective emission from macroscopically separated emitters
Kanupriya Sinha, Pierre Meystre, Elizabeth A. Goldschmidt +3
We study the collective radiative decay of a system of two two-level emitters coupled to a one-dimensional waveguide in a regime where their separation is comparable to the coheren…
Collective effects in Casimir-Polder forces
Kanupriya Sinha, B. Prasanna Venkatesh, Pierre Meystre
We study cooperative phenomena in the fluctuation-induced forces between a surface and a system of neutral two-level quantum emitters prepared in a coherent collective state, showi…
Repulsive vacuum-induced forces on a magnetic particle
Kanupriya Sinha
We study the possibility of obtaining a repulsive vacuum-induced force for a magnetic point particle near a surface. Considering the toy model of a particle with an electric-dipole…
On-chip quantum interference of a superconducting microsphere
H. Pino, J. Prat-Camps, K. Sinha +2
We propose and analyze an all-magnetic scheme to perform a Young's double slit experiment with a micron-sized superconducting sphere of mass amu. We show that i…
Mirror-Field Entanglement in a Microscopic model for Quantum Optomechanics
Kanupriya Sinha, Shih-Yuin Lin, B. L. Hu
We use a microscopic model, the Mirror-Oscillator-Field (MOF) model proposed by Galley, Behunin and Hu [Phys. Rev. A 87, 043832 (2013)], to describe the quantum entanglement betwee…
Effect of Interatomic Separation on Entanglement Dynamics in a Two-Atom Two-Mode Model
K. Sinha, N. I. Cummings, B. L. Hu
We analyze the time evolution of quantum entanglement in a model consisting of two two-level atoms interacting with a two-mode electromagnetic field for a variety of initial states…
Protecting and Dynamically Generating Entanglement in a Two-Atom Two-Field-Mode Model
K. Sinha, N. Cummings, B. L. Hu
We analyze the time evolution of quantum entanglement in a model consisting of two two-level atoms interacting with a two-mode electromagnetic field for a variety of initial states…
