Magnons reveal topology and dynamics of a skyrmion crystal

Raphael Ayache, Nilotpal Chakraborty, Manabendra Kuiri +11

Although individual skyrmions are topologically protected objects, their cooperative crystalline order is fragile, easily disrupted by thermal fluctuations or other external pertur…

Non-reciprocal Ising gauge theory

Nilotpal Chakraborty, Anton Souslov, Claudio Castelnovo

Non-reciprocity and geometric frustration enable many-body systems to avoid crystalline order and instead exhibit complex, liquid-like behavior. Here we show that their interplay i…

Entanglemons: Cross-platform protected qubits from entanglement

Nilotpal Chakraborty, Roderich Moessner, Benoit Doucot

A crucial ingredient for scalable fault-tolerant quantum computing is the construction of logical qubits with low error rates and intrinsic noise protection. We propose a cross-pla…

Fractional diffusion without disorder in two dimensions

Nilotpal Chakraborty, Markus Heyl, Roderich Moessner

We analyse how simple local constraints in two dimensions lead a defect to exhibit robust, non-transient, and tunable, subdiffusion. We uncover a rich dynamical phenomenology reali…

Entanglement smectic and stripe order

Nilotpal Chakraborty, Roderich Moessner, Benoit Doucot

Spontaneous symmetry breaking and more recently entanglement are two cornerstones of quantum matter. We introduce the notion of anisotropic entanglement ordered phases, where the s…
