String theory seeks to unite quantum physics with the theory of general relativity in the field of theoretical physics.
Some alternatives to string theory include loop quantum gravity, quantum field theory, and causal dynamical triangulation.
As of now, string theory has not been replaced by any other theory in the field of theoretical physics. It remains a prominent and actively researched area of study.
The regge slope is significant in theoretical physics because it helps describe the behavior of particles in high-energy collisions. It is a key concept in understanding the scattering amplitudes of particles and plays a crucial role in the study of quantum field theory and string theory.
A quantum field is a physical field defined in quantum field theory, which is a theoretical framework that combines quantum mechanics and special relativity. These fields describe the fundamental interactions between particles and can be thought of as excitations or vibrations in a field that permeates all of space.

Dr. Professor Smith is an expert in quantum physics, specializing in quantum mechanics, quantum computing, and quantum field theory. His research focuses on understanding the behavior of particles at the quantum level and developing new technologies based on quantum principles.
There are two answers here really. I'll begin by describing why it's different from Quantum Mechanics. Quantum Mechanics studies non-relativistic particles (or waves), that is particles where effects from Einstein's relativity are unnoticeable because the particle is travelling at a speed much slower than the speed of light. Additionally people study N-body problems, which means to say that we think of a system with precisely N particles. Quantum Field Theory on the other hand is a generalisation that attempts to study particles where relativistic effects can be noticeable. This has several additional problems, one of which is that it predicts that particles can be created or destroyed which means we're no longer in an N-body system. Quantum Field Theory was invented in order to deal with these problems and as such it generalises Quantum Mechanics. There are several additional complexities that Quantum Field Theory has a result of this, in particular there has always been problems that infinities show up in calculations that have caused various difficulties, though these have been solved by techniques in Physics known as renormalisation. To date Quantum Field Theory is the best theory of Physics that is experimentally verified. String Theory offers a possible improvement but it has yet (at least to my knowledge) to any experimental justification. Quantum Field Theory fully explains (nearly) everything we currently know about particle physics, including quantum effects in electromagnetism, nuclear physics and condensed matter physics. The outstanding problem in this field is to try and incorporate Einstein's theory of gravity. This is considered by many as one of the big outstanding problems in Physics today.
