21st-century Danish physicists

The term "21st-century Danish physicists" refers to a group of scientists from Denmark who have made significant contributions to various fields of physics during the 21st century. While there are many notable physicists from Denmark, a few key figures stand out: 1. **Niels Bohr** (although primarily active in the early 20th century, his legacy continues to influence modern physics) - His foundational work in quantum mechanics and atomic structure laid much of the groundwork for contemporary physics.

Jan Ambjørn is a theoretical physicist known for his work in the field of quantum gravity, and in particular for his contributions to loop quantum gravity and causal set theory. His research often explores the connections between quantum mechanics and general relativity, and he has been involved in various aspects of understanding how spacetime might be represented at the quantum level.

Liv Hornekær is a name that may refer to various individuals, but there is a notable Danish artist by that name. She is known for her work in the field of visual arts, particularly painting. Her artworks often explore themes related to nature and personal experiences, often using vibrant colors and abstract forms.

Poul S. Jessen is a notable figure in the field of optics and photonics. He is known for his contributions to areas such as optical communications, quantum optics, and advanced imaging techniques. Jessen has been involved in research that often intersects with various applications of physics and engineering, and he has published numerous scholarly papers.
