Entanglement Sudden Death: Eberly's Work and the Limits of Local Dynamics
Abhaya S. Hegde, Songbo Xie
Entanglement sudden death (ESD), explored through a series of works by Yu and Eberly, supports the notion of entanglement vanishing abruptly and completely at a finite time, even w…
Tightening the thermodynamic uncertainty relations with null-entropy events: What we learn when nothing happens
Abhaya S. Hegde, André M. Timpanaro, Gabriel T. Landi
Fluctuation theorems establish that thermodynamic processes at the microscale can occasionally result in negative entropy production. At the microscale, another distinct possibilit…
Framework for fluctuating times and counting observables in stochastic excursions
Guilherme Fiusa, Pedro E. Harunari, Abhaya S. Hegde +1
Many natural systems exhibit dynamics characterized by alternating phases or recurring sets of states. Describing the fluctuations of such systems over stochastic trajectories is n…
Counting observables in stochastic excursions
Guilherme Fiusa, Pedro E. Harunari, Abhaya S. Hegde +1
Understanding fluctuations of observables across stochastic trajectories is essential for various fields of research, from quantum thermal machines to biological motors. We introdu…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Time-resolved Stochastic Dynamics of Quantum Thermal Machines
Abhaya S. Hegde, Patrick P. Potts, Gabriel T. Landi
Steady-state quantum thermal machines are typically characterized by a continuous flow of heat between different reservoirs. However, at the level of discrete stochastic realizatio…
Optical realization of one-dimensional generalized split-step quantum walks
P. A. Ameen Yasir, Abhaya S. Hegde, C. M. Chandrashekar
Quantum walks are more than tools for building quantum algorithms. They have been used effectively to model and simulate quantum dynamics in many complex physical processes. Partic…
Multi-bit quantum random number generator from path-entangled single photons
K. Muhammed Shafi, Prateek Chawla, Abhaya S. Hegde +3
Measurement outcomes on quantum systems exhibit inherent randomness and are fundamentally nondeterministic. This has enabled quantum physics to set new standards for the generation…
Characterization of anomalous diffusion in one-dimensional quantum walks
Abhaya S. Hegde, C. M. Chandrashekar
Quantum walks are known to propagate quadratically faster than their classical counterparts and are used to model dynamics in various quantum systems. The spread of the quantum wal…
Open quantum dynamics with singularities: Master equations and degree of non-Markovianity
Abhaya S. Hegde, K. P. Athulya, Vijay Pathak +2
Master equations describing open quantum dynamics are typically first order differential equations. When such dynamics brings the trajectories in state space of more than one initi…
