Semiclassical fast-forward shortcuts to adiabaticity
Ayoti Patra, Christopher Jarzynski
In fast forward quantum shortcuts to adiabaticity, a designed potential steers a wavefunction to evolve from the 'th eigenstate of an initial Hamiltonian $\hat H(0…
Shortcuts to Thermodynamic Computing: The Cost of Fast and Faithful Erasure
A. B. Boyd, A. Patra, C. Jarzynski +1
Landauer's Principle states that the energy cost of information processing must exceed the product of the temperature and the change in Shannon entropy of the information-bearing d…
Shortcuts to adiabaticity using flow fields
Ayoti Patra, Christopher Jarzynski
A is a recipe for generating adiabatic evolution at an arbitrary pace. Shortcuts have been developed for quantum, classical and (most recently)…
Fast forward to the classical adiabatic invariant
Christopher Jarzynski, Sebastian Deffner, Ayoti Patra +1
We show how the classical action, an adiabatic invariant, can be preserved under non-adiabatic conditions. Specifically, for a time-dependent Hamiltonian in o…
Classical and quantum shortcuts to adiabaticity in a tilted piston
Ayoti Patra, Christopher Jarzynski
Adiabatic quantum state evolution can be accelerated through a variety of shortcuts to adiabaticity. In one approach, a counterdiabatic quantum Hamiltonian is constru…
Quenching Dynamics and Quantum Information
Tanay Nag, Amit Dutta, Ayoti Patra
We review recent studies on the measures of zero temperature quantum correlations namely, the quantum entanglement (concurrence) and discord present in the final state of a transve…
Quantum Discord in a spin-1/2 transverse XY Chain Following a Quench
Tanay Nag, Ayoti Patra, Amit Dutta
We report a study on the zero-temperature quantum discord as a measure of two-spin correlation of a transverse XY spin chain following a quench across a quantum critical point and…
Path dependent scaling of geometric phase near a quantum multi-critical point
Ayoti Patra, Victor Mukherjee, Amit Dutta
We study the geometric phase of the ground state in a one-dimensional transverse XY spin chain in the vicinity of a quantum multi-critical point. We approach the multi-critical poi…
