Fermions -- and that includes leptons and neutrinos -- all have a spin value of one-half. This is also true for every quark.
Pions has zero spin.
A quantum state with zero spin in physics is called a singlet state. This means that the total angular momentum of the system is zero. This term is commonly used in the context of quantum mechanics to describe certain states of particles.
The theoretical Higgs boson would have zero spin. The neutral and charged pions also have zero spin. Two entangled particles, each with spin opposite to each other, would be a quantum state with zero net spin. Atoms may also have zero spin, if they are in what is known as S-states (e.g. the ground state of hydrogen).
A quantum state with zero spin is a state where the angular momentum of the system is zero. This means that the system has no intrinsic angular momentum or spin. In other words, it has a spin quantum number of 0.

In theoretical physics, a singlet usually refers to a one-dimensional representation (e.g. a particle with vanishing spin). It may also refer to two or more particles prepared in a correlated state, such that the total angular momentum of the state is zero.Singlets frequently occur in atomic physics as one of the two ways in which the spin of two electrons can be combined; the other being a triplet. A single electron has spin 1/2, and transforms as a doublet, that is, as the fundamental representation of the rotation group SU(2). The product of two doublet representations can be decomposed into the sum of the adjoint representation (the triplet) and the trivial representation, the singlet. More prosaically, a pair of electron spins can be combined to form a state of total spin 1 and a state of spin 0.The singlet state formed from a pair of electrons has many peculiar properties, and plays a fundamental role in the EPR paradox and quantum entanglement. In Dirac notation this EPR state is usually represented as:
Spin zero particles have no intrinsic angular momentum, meaning they do not spin on their axis. They are scalar particles, meaning they have no directionality in their properties. They are also bosons, which means they follow Bose-Einstein statistics and can occupy the same quantum state. Examples of spin zero particles include the Higgs boson.
In quantum mechanics, the zero mode represents the lowest energy state of a system. It is significant because it serves as a reference point for measuring the energy levels of other states in the system. Additionally, the zero mode plays a crucial role in understanding the behavior and properties of quantum systems.
Spin is the measure of the angle of the particle. The angle determines whether the particle is a scalar or a vector. Spin zero indicates a positive scalar; Spin 1/2 is pi/2 angle and indicates a positive vector; spin 1 is pi degrees and indicates a negative scalar; spin 3/2 indicates a negative vector.Physics Particles are Quaternions containing a scalar and vector parts, the unit quaternion is described as:cos(Angle) + v sin(Angle).Quantities in Physics are in general Quaternion, e.g. Gravitatioanl Energy W=-mu/r + cP.Bosons and Fermions represent pure scalars and Vectors with angle being multiples of pi or spin. spin is symbolic of 180 degrees spin zero is zero degrees. spin 1/2 is 90 degrees etc. When angles are not multiples of pi/2 the quantity is a Quaternion and contains a scalar (Boson) and Vector (Fermion).
Such cold temperatures - a fraction of a microkelvin! - don't exist in nature. They can only be created artificially.
BE condensate is the state of matter below solids, like plasma is above gases. It only occurs at absolute zero(0˚ Kelvin, -273.15˚ Celsius, -459.67˚ Fahrenheit) or for some elements a few billionths of a Kelvin degree above absolute zero.
You have described a photon. Fairly well, actually; good job.
Nanoparticles and quantum dots are the zero dimensional structures.
