Testing causal quantum theory. [PDF]
Proc Math Phys Eng Sci, 2018 Causal quantum theory assumes that measurements or collapses are well-defined physical processes, localized in space–time, and never give perfectly reliable outcomes and that the outcome of one measurement only influences the outcomes of others within its future light cone.

AAPPS Bulletin, 2023 We present a microscopic many-body calculation of the nonlinear two-dimensional coherent spectroscopy (2DCS) of trion-polaritons and exciton-polaritons in charge-tunable transition-metal-dichalcogenides monolayers placed in an optical microcavity.

Thermally stable p-wave repulsive Fermi polaron without a two-body bound state
AAPPS Bulletin, 2023 We theoretically investigate the polaron physics of an impurity immersed in a two-dimensional Fermi sea, interacting via a p-wave interaction at finite temperature.

Quantum Microeconomics Theory [PDF]
SSRN Electronic Journal, 2015 The quantum macroeconomics theory is formulated for the first time, assuming that the business cycle has the discrete-time oscillations spectrum in analogy with the electronics excitations discrete-time spectrum in the Bohr’s atom model in the quantum physics.

Compatible quantum theory [PDF]
Reports on Progress in Physics, 2014 Formulations of quantum mechanics can be characterized as realistic, operationalist, or a combination of the two. In this paper a realistic theory is defined as describing a closed system entirely by means of entities and concepts pertaining to the system. An operationalist theory, on the other hand, requires in addition entities external to the system.

Quantum Embedding Theories [PDF]
Accounts of Chemical Research, 2016 In complex systems, it is often the case that the region of interest forms only one part of a much larger system. The idea of joining two different quantum simulations - a high level calculation on the active region of interest, and a low level calculation on its environment - formally defines a quantum embedding.

New Journal of Physics, 2021 We reconsider the all-optical weak homodyne-measurement based experimental schemes aimed at revealing Bell nonclassicality (‘nonlocality’) of a single photon. We focus on the schemes put forward by Tan et al (TWC, 1991) and Hardy (1994).

Weak versus Deterministic Macroscopic Realism, and Einstein–Podolsky–Rosen’s Elements of Reality
Entropy, 2023 The violation of a Leggett–Garg inequality confirms the incompatibility between quantum mechanics and the combined premises (called macro-realism) of macroscopic realism (MR) and noninvasive measurability (NIM).

Simulating Gaussian boson sampling quantum computers
AAPPS Bulletin, 2023 A growing cohort of experimental linear photonic networks implementing Gaussian boson sampling (GBS) have now claimed quantum advantage. However, many open questions remain on how to effectively verify these experimental results, as scalable methods are ...

Simplified quantum optical Stokes observables and Bell’s theorem
Scientific Reports, 2022 We discuss a simplified form of Stokes operators for quantum optical fields that involve the known concept of binning. Behind polarization analyzer photon numbers (more generally intensities) are measured.
