PULSUS: Direct Frequency-Domain Multidimensional Spectroscopy Beyond the Impulsive Rotating-Wave Approximation
Alfonso Castillo-Gonzalez, Alfonso Castillo-Gonzolez, Eric R. Bittner +1
We introduce PULSUS, a direct frequency-domain framework for multidimensional spectroscopy of open quantum systems beyond the impulsive rotating-wave approximation. Coherence-frequ…
SAKE: Spectral Autodiff Kernel Expansion for Geometric Liouvillian Transport. A Differential-Geometric Framework for Response Transport in Quantum Dynamical Systems
Eric R. Bittner, Carlos Silva-Acuna, Hao Li +1
We introduce the Spectral Autodiff Kernel Expansion (SAKE), a differentiable computational framework for transporting nonlinear spectroscopic response between neighboring quantum d…
State--Generator Geometry of Open Quantum Systems: Compatibility and Covariant Transport
Eric R. Bittner, Carlos Silva-Acuna
We develop a geometry for transporting stationary-state response across the control space of an open quantum system. A physical model is represented by the ordered pair of its stat…
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…
Liouvillian Geometry of Multidimensional Spectra: Pathway Transport and Observational Holonomy in Open Quantum Systems
Eric R. Bittner, Carlos Silva-Acuña, Hao Li
Liouville pathways provide the conceptual foundation for interpreting multidimensional spectroscopies and are commonly represented as independent contributions to the nonlinear res…
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…
Graph Symmetry Organizes Exceptional Dynamics in Open Quantum Systems
Eric R. Bittner, Bhavay Tyagi, Kevin E. Bassler
Exceptional points (EPs), indicative of parity-time (PT) symmetry breaking, play a central role in non-Hermitian physics, yet most studies begin from deliberately engineered effect…
