Liouvillian Geometry of Multidimensional Spectra: Pathway Transport and Observational Holonomy in Open Quantum Systems
Eric R. Bittner, Carlos Silva-Acuña, Carlos Silva-Acuña +1
Liouville pathways provide the conceptual foundation for interpreting multidimensional spectroscopies and are commonly represented as independent contributions to the nonlinear res…
Geometric Response in Open Quantum Systems: Coherence, Curvature, and Susceptibility
Eric R. Bittner, Carlos Silva-Acuña
We develop a response-geometric framework for open quantum systems by decomposing the stationary-state response tensor into symmetric and antisymmetric sectors. The symmetric secto…
Holonomy and Complementarity in Open Quantum Systems
Eric R Bittner
Complementarity relations constrain the distribution of coherence, predictability, and openness in quantum systems. Here we show that, in open quantum systems, these local constrai…
Phase-Reference Control of Steady-State Entanglement in Open Quantum Systems
Areeda Ayoub, Alfonso Castillo-Gonzalez, Eric R Bittner
We show that steady-state entanglement in open quantum systems is controlled by the phase reference of a phase-sensitive reservoir. Using a covariance-matrix approach for Gaussian-…
Geometric Thermodynamics in Open Quantum Systems: Coherence, Curvature, and Work
Eric R. Bittner
We formulate a geometric framework for quasistatic thermodynamics in open quantum systems by parameterizing the dynamics on a control manifold. In the quasistatic limit, the system…
Thermalization Regimes in a Chaotic Tavis-Cummings Model
Sameer Dambal, Eric R. Bittner
This work investigates the emergent thermalization regimes in a chaotic Tavis-Cummings (TC) model and their implications in quantum spectroscopy. While the TC model is a cornerston…
