Quantum theory based on real numbers can be experimentally falsified. [PDF]
Nature, 2021 Although complex numbers are essential in mathematics, they are not needed to describe physical experiments, as those are expressed in terms of probabilities, hence real numbers.

Quantum theory of the nonlinear Hall effect. [PDF]
Nat Commun, 2021 The nonlinear Hall effect is an unconventional response, in which a voltage can be driven by two perpendicular currents in the Hall-bar measurement. Unprecedented in the family of the Hall effects, it can survive time-reversal symmetry but is sensitive ...

The quantum theory of light. [PDF]
Philos Trans A Math Phys Eng SciWe present a brief introduction to the quantum theory of light as it is understood in the field of quantum optics. Our aim is not to review the topic, which would require a very extensive article (or even a book of several volumes) but rather to provide ...

Theoretical framework for higher-order quantum theory. [PDF]
Proc Math Phys Eng Sci, 2019 Higher-order quantum theory is an extension of quantum theory where one introduces transformations whose input and output are transformations, thus generalizing the notion of channels and quantum operations. The generalization then goes recursively, with

Quantum theory cannot consistently describe the use of itself. [PDF]
Nat Commun, 2018 Quantum theory provides an extremely accurate description of fundamental processes in physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic, domain in which it has been tested experimentally.

Testing Real Quantum Theory in an Optical Quantum Network. [PDF]
Physical Review Letters, 2021 Quantum theory is commonly formulated in complex Hilbert spaces. However, the question of whether complex numbers need to be given a fundamental role in the theory has been debated since its pioneering days.

Ruling Out Real-Valued Standard Formalism of Quantum Theory. [PDF]
Physical Review Letters, 2021 Standard quantum theory was formulated with complex-valued Schrödinger equations, wave functions, operators, and Hilbert spaces. Previous work attempted to simulate quantum systems using only real numbers by exploiting an enlarged Hilbert space.

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.

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).
