Topology1,2,3 and interactions are foundational concepts in the modern understanding of quantum matter. Their nexus yields three important research directions: (1) the competition between distinct interactions, as in several intertwined phases, (2) the interplay between interactions and topology that dr...
State estimation is concerned with reconciling noisy observations of a physical system with the mathematical model believed to predict its behaviour for the purpose of inferring unmeasurable states and denoising measurable ones1,2. Traditional state-estimation techniques rely on strong assumptions about the...
Hence, substituting λ=h/mε and introducing the molecular units of volume and temperature 2 πNσ3/3 and ε/k, the expression for B* of the corresponding-states principle can be written: (3.73)B*=B2πNσ3/3=(4T*)1/4∑0∞ci(4T*)1/2+(Λσ)2(4T*)13/12∑0∞ci(1)(4T*)1...
whereJis the rotationalquantum number0, 1, 2, …. WhenBv,Dv, etc. are expressed in wavenumbers (cm−1), the right-hand side of this equation must be multiplied byhcto obtain the units of energy. Each state has a degeneracygJof 2J+ 1; i.e., there are 2J+ 1 states with the ...
Gestational weight gain (GWG) is a routinely monitored aspect of pregnancy health, yet critical gaps remain about optimal GWG in pregnant people from socially marginalized groups, or with pre-pregnancy body mass index (BMI) in the lower or upper extremes
thoughts carry almost the same weight as real life experiences and are subjected to the same cognitive biases, just in the opposite direction. For example, when someone experiences something that goes against their world view, they will tend to dismiss it by coming up with reasons why the exper...
