Anomalous heating in a colloidal system
Avinash Kumar, Raphael Chetrite, John Bechhoefer
We report anomalous heating in a colloidal system, the first observation of the inverse Mpemba effect, where an initially cold system heats up faster than an identical warm system…
Producing superfluid circulation states using phase imprinting
Avinash Kumar, Romain Dubessy, Thomas Badr +4
We propose a method to prepare states of given quantized circulation in annular Bose-Einstein condensates (BEC) confined in a ring trap using the method of phase imprinting without…
Combined effect of Fluid Rheology and Surface Modification on Eletrokinetic Energy Generation through Finite Length Microchannel
Aditya Patwari, Avinash Kumar, Chirodeep Bakli +1
Electrokinetic energy conversion provides a scheme for energy harvesting and storage for on-chip applications. However, the major drawback of electrokinetic energy conversion is it…
Residual Reinforcement Learning for Robot Control
Tobias Johannink, Shikhar Bahl, Ashvin Nair +6
Conventional feedback control methods can solve various types of robot control problems very efficiently by capturing the structure with explicit models, such as rigid body equatio…
Context Switching for Secure Multi-programming of Near-Term Quantum Computers
Avinash Kumar, Meng Wang, Chenxu Liu +3
Multi-programming quantum computers improve device utilization and throughput. However, crosstalk from concurrent two-qubit CNOT gates poses security risks, compromising the fideli…
A versatile ring trap for quantum gases
Mathieu de Goër de Herve, Yanliang Guo, Camilla de Rossi +5
We report on the confinement of a Bose-Einstein condensate in an annular trap with widely tunable parameters. The trap relies on a combination of magnetic, optical and radio-freque…
